## CMake configuration file of gflags project
##
## This CMakeLists.txt defines some gflags specific configuration variables
## using the "gflags_define" utility macro. The default values of these variables
## can be overridden either on the CMake command-line using the -D option of
## the cmake command or in a super-project which includes the gflags source
## tree by setting the GFLAGS_<varname> CMake variables before adding the
## gflags source directory via CMake's "add_subdirectory" command. Only when
## the non-cached variable GFLAGS_IS_SUBPROJECT has a value equivalent to FALSE,
## these configuration variables are added to the CMake cache so they can be
## edited in the CMake GUI. By default, GFLAGS_IS_SUBPROJECT is set to TRUE when
## the CMAKE_SOURCE_DIR is not identical to the directory of this CMakeLists.txt
## file, i.e., the top-level directory of the gflags project source tree.
##
## When this project is a subproject (GFLAGS_IS_SUBPROJECT is TRUE), the default
## settings are such that only the static single-threaded library is built without
## installation of the gflags files. The "gflags" target is in this case an ALIAS
## library target for the "gflags_nothreads_static" library target. Targets which
## depend on the gflags library should link to the "gflags" library target.
##
## Example CMakeLists.txt of user project which requires separate gflags installation:
## cmake_minimum_required(VERSION 2.8.12 FATAL_ERROR)
##
## project(Foo)
##
## find_package(gflags REQUIRED)
##
## add_executable(foo src/foo.cc)
## target_link_libraries(foo gflags)
##
## Example CMakeLists.txt of user project which requires separate single-threaded static gflags installation:
## cmake_minimum_required(VERSION 2.8.12 FATAL_ERROR)
##
## project(Foo)
##
## find_package(gflags COMPONENTS nothreads_static)
##
## add_executable(foo src/foo.cc)
## target_link_libraries(foo gflags)
##
## Example CMakeLists.txt of super-project which contains gflags source tree:
## cmake_minimum_required(VERSION 2.8.12 FATAL_ERROR)
##
## project(Foo)
##
## add_subdirectory(gflags)
##
## add_executable(foo src/foo.cc)
## target_link_libraries(foo gflags)
##
## Variables to configure the source files:
## - GFLAGS_IS_A_DLL
## - GFLAGS_NAMESPACE
## - GFLAGS_ATTRIBUTE_UNUSED
## - GFLAGS_INTTYPES_FORMAT
##
## Variables to configure the build:
## - GFLAGS_SOVERSION
## - GFLAGS_BUILD_SHARED_LIBS
## - GFLAGS_BUILD_STATIC_LIBS
## - GFLAGS_BUILD_gflags_LIB
## - GFLAGS_BUILD_gflags_nothreads_LIB
## - GFLAGS_BUILD_TESTING
## - GFLAGS_BUILD_PACKAGING
##
## Variables to configure the installation:
## - GFLAGS_INCLUDE_DIR
## - GFLAGS_LIBRARY_INSTALL_DIR or LIB_INSTALL_DIR or LIB_SUFFIX
## - GFLAGS_INSTALL_HEADERS
## - GFLAGS_INSTALL_SHARED_LIBS
## - GFLAGS_INSTALL_STATIC_LIBS

Installing a binary distribution package
========================================
No official binary distribution packages are provided by the gflags developers.
There may, however, be binary packages available for your OS. Please consult
also the package repositories of your Linux distribution.
For example on Debian/Ubuntu Linux, gflags can be installed using the
following command:
sudo apt-get install libgflags-dev
Compiling the source code with CMake
=========================
The build system of gflags is since version 2.1 based on [CMake](http://cmake.org).
The common steps to build, test, and install software are therefore:
1. Extract source files.
2. Create build directory and change to it.
3. Run CMake to configure the build tree.
4. Build the software using selected build tool.
5. Test the built software.
6. Install the built files.
On Unix-like systems with GNU Make as build tool, these build steps can be
summarized by the following sequence of commands executed in a shell,
where ```$package``` and ```$version``` are shell variables which represent
the name of this package and the obtained version of the software.
$ tar xzf gflags-$version-source.tar.gz
$ cd gflags-$version
$ mkdir build && cd build
$ ccmake ..
- Press 'c' to configure the build system and 'e' to ignore warnings.
- Set CMAKE_INSTALL_PREFIX and other CMake variables and options.
- Continue pressing 'c' until the option 'g' is available.
- Then press 'g' to generate the configuration files for GNU Make.
$ make
$ make test (optional)
$ make install (optional)
In the following, only gflags-specific CMake settings available to
configure the build and installation are documented. Note that most of these
variables are for advanced users and binary package maintainers only.
They usually do not have to be modified.
CMake Option | Description
--------------------------- | -------------------------------------------------------
CMAKE_INSTALL_PREFIX | Installation directory, e.g., "/usr/local" on Unix and "C:\Program Files\gflags" on Windows.
BUILD_SHARED_LIBS | Request build of dynamic link libraries.
BUILD_STATIC_LIBS | Request build of static link libraries. Implied if BUILD_SHARED_LIBS is OFF.
BUILD_PACKAGING | Enable binary package generation using CPack.
BUILD_TESTING | Build tests for execution by CTest.
BUILD_NC_TESTS | Request inclusion of negative compilation tests (requires Python).
BUILD_CONFIG_TESTS | Request inclusion of package configuration tests (requires Python).
BUILD_gflags_LIBS | Request build of multi-threaded gflags libraries (if threading library found).
BUILD_gflags_nothreads_LIBS | Request build of single-threaded gflags libraries.
GFLAGS_NAMESPACE | Name of the C++ namespace to be used by the gflags library. Note that the public source header files are installed in a subdirectory named after this namespace. To maintain backwards compatibility with the Google Commandline Flags, set this variable to "google". The default is "gflags".
GFLAGS_INTTYPES_FORMAT | String identifying format of built-in integer types.
GFLAGS_INCLUDE_DIR | Name of headers installation directory relative to CMAKE_INSTALL_PREFIX.
LIBRARY_INSTALL_DIR | Name of library installation directory relative to CMAKE_INSTALL_PREFIX.
INSTALL_HEADERS | Request installation of public header files.
Using gflags with [Bazel](http://bazel.io)
=========================
To use gflags in a Bazel project, map it in as an external dependency by editing
your WORKSPACE file:
git_repository(
name = "com_github_gflags_gflags",
commit = "<INSERT COMMIT SHA HERE>",
remote = "https://github.com/gflags/gflags.git",
)
bind(
name = "gflags",
actual = "@com_github_gflags_gflags//:gflags",
)
You can then add `//external:gflags` to the `deps` section of a `cc_binary` or
`cc_library` rule, and `#include <gflags/gflags.h>` to include it in your source
code.

[![Build Status](https://travis-ci.org/gflags/gflags.svg?branch=master)](https://travis-ci.org/gflags/gflags)
[![Build status](https://ci.appveyor.com/api/projects/status/4ctod566ysraus74/branch/master?svg=true)](https://ci.appveyor.com/project/schuhschuh/gflags/branch/master)
The documentation of the gflags library is available online at https://gflags.github.io/gflags/.
11 July 2017
------------
I've just released gflags 2.2.1.
This maintenance release primarily fixes build issues on Windows and
false alarms reported by static code analyzers.
Please report any further issues with this release using the GitHub issue tracker.
25 November 2016
----------------
I've finally released gflags 2.2.0.
This release adds support for use of the gflags library as external dependency
not only in projects using CMake, but also [Bazel](https://bazel.build/),
or [pkg-config](https://www.freedesktop.org/wiki/Software/pkg-config/).
One new minor feature is added in this release: when a command flag argument
contains dashes, these are implicitly converted to underscores.
This is to allow those used to separate words of the flag name by dashes
to do so, while the flag variable names are required to use underscores.
Memory leaks reported by valgrind should be resolved by this release.
This release fixes build errors with MS Visual Studio 2015.
Please report any further issues with this release using the GitHub issue tracker.
24 March 2015
-------------
I've just released gflags 2.1.2.
This release completes the namespace change fixes. In particular,
it restores binary ABI compatibility with release version 2.0.
The deprecated "google" namespace is by default still kept as
primary namespace while symbols are imported into the new "gflags" namespace.
This can be overridden using the CMake variable GFLAGS_NAMESPACE.
Other fixes of the build configuration are related to the (patched)
CMake modules FindThreads.cmake and CheckTypeSize.cmake. These have
been removed and instead the C language is enabled again even though
gflags is written in C++ only.
This release also marks the complete move of the gflags project
from Google Code to GitHub. Email addresses of original issue
reporters got lost in the process. Given the age of most issue reports,
this should be negligable.
Please report any further issues using the GitHub issue tracker.
30 March 2014
-------------
I've just released gflags 2.1.1.
This release fixes a few bugs in the configuration of gflags\_declare.h
and adds a separate GFLAGS\_INCLUDE\_DIR CMake variable to the build configuration.
Setting GFLAGS\_NAMESPACE to "google" no longer changes also the include
path of the public header files. This allows the use of the library with
other Google projects such as glog which still use the deprecated "google"
namespace for the gflags library, but include it as "gflags/gflags.h".
20 March 2014
-------------
I've just released gflags 2.1.
The major changes are the use of CMake for the build configuration instead
of the autotools and packaging support through CPack. The default namespace
of all C++ symbols is now "gflags" instead of "google". This can be
configured via the GFLAGS\_NAMESPACE variable.
This release compiles with all major compilers without warnings and passed
the unit tests on Ubuntu 12.04, Windows 7 (Visual Studio 2008 and 2010,
Cygwin, MinGW), and Mac OS X (Xcode 5.1).
The SVN repository on Google Code is now frozen and replaced by a Git
repository such that it can be used as Git submodule by projects. The main
hosting of this project remains at Google Code. Thanks to the distributed
character of Git, I can push (and pull) changes from both GitHub and Google Code
in order to keep the two public repositories in sync.
When fixing an issue for a pull request through either of these hosting
platforms, please reference the issue number as
[described here](https://code.google.com/p/support/wiki/IssueTracker#Integration_with_version_control).
For the further development, I am following the
[Git branching model](http://nvie.com/posts/a-successful-git-branching-model/)
with feature branch names prefixed by "feature/" and bugfix branch names
prefixed by "bugfix/", respectively.
Binary and source [packages](https://github.com/schuhschuh/gflags/releases) are available on GitHub.
14 January 2014
---------------
The migration of the build system to CMake is almost complete.
What remains to be done is rewriting the tests in Python such they can be
executed on non-Unix platforms and splitting them up into separate CTest tests.
Though merging these changes into the master branch yet remains to be done,
it is recommended to already start using the
[cmake-migration](https://github.com/schuhschuh/gflags/tree/cmake-migration) branch.
20 April 2013
-------------
More than a year has past since I (Andreas) took over the maintenance for
`gflags`. Only few minor changes have been made since then, much to my regret.
To get more involved and stimulate participation in the further
development of the library, I moved the project source code today to
[GitHub](https://github.com/schuhschuh/gflags).
I believe that the strengths of [Git](http://git-scm.com/) will allow for better community collaboration
as well as ease the integration of changes made by others. I encourage everyone
who would like to contribute to send me pull requests.
Git's lightweight feature branches will also provide the right tool for more
radical changes which should only be merged back into the master branch
after these are complete and implement the desired behavior.
The SVN repository remains accessible at Google Code and I will keep the
master branch of the Git repository hosted at GitHub and the trunk of the
Subversion repository synchronized. Initially, I was going to simply switch the
Google Code project to Git, but in this case the SVN repository would be
frozen and force everyone who would like the latest development changes to
use Git as well. Therefore I decided to host the public Git repository at GitHub
instead.
Please continue to report any issues with gflags on Google Code. The GitHub project will
only be used to host the Git repository.
One major change of the project structure I have in mind for the next weeks
is the migration from autotools to [CMake](http://www.cmake.org/).
Check out the (unstable!)
[cmake-migration](https://github.com/schuhschuh/gflags/tree/cmake-migration)
branch on GitHub for details.
25 January 2012
---------------
I've just released gflags 2.0.
The `google-gflags` project has been renamed to `gflags`. I
(csilvers) am stepping down as maintainer, to be replaced by Andreas
Schuh. Welcome to the team, Andreas! I've seen the energy you have
around gflags and the ideas you have for the project going forward,
and look forward to having you on the team.
I bumped the major version number up to 2 to reflect the new community
ownership of the project. All the [changes](ChangeLog.txt)
are related to the renaming. There are no functional changes from
gflags 1.7. In particular, I've kept the code in the namespace
`google`, though in a future version it should be renamed to `gflags`.
I've also kept the `/usr/local/include/google/` subdirectory as
synonym of `/usr/local/include/gflags/`, though the former name has
been obsolete for some time now.
18 January 2011
---------------
The `google-gflags` Google Code page has been renamed to
`gflags`, in preparation for the project being renamed to
`gflags`. In the coming weeks, I'll be stepping down as
maintainer for the gflags project, and as part of that Google is
relinquishing ownership of the project; it will now be entirely
community run. The name change reflects that shift.
20 December 2011
----------------
I've just released gflags 1.7. This is a minor release; the major
change is that `CommandLineFlagInfo` now exports the address in memory
where the flag is located. There has also been a bugfix involving
very long --help strings, and some other minor [changes](ChangeLog.txt).
29 July 2011
------------
I've just released gflags 1.6. The major new feature in this release
is support for setting version info, so that --version does something
useful.
One minor change has required bumping the library number:
`ReparseCommandlineFlags` now returns `void` instead of `int` (the int
return value was always meaningless). Though I doubt anyone ever used
this (meaningless) return value, technically it's a change to the ABI
that requires a version bump. A bit sad.
There's also a procedural change with this release: I've changed the
internal tools used to integrate Google-supplied patches for gflags
into the opensource release. These new tools should result in more
frequent updates with better change descriptions. They will also
result in future `ChangeLog` entries being much more verbose (for better
or for worse).
See the [ChangeLog](ChangeLog.txt) for a full list of changes for this release.
24 January 2011
---------------
I've just released gflags 1.5. This release has only minor changes
from 1.4, including some slightly better reporting in --help, and
an new memory-cleanup function that can help when running gflags-using
libraries under valgrind. The major change is to fix up the macros
(`DEFINE_bool` and the like) to work more reliably inside namespaces.
If you have not had a problem with these macros, and don't need any of
the other changes described, there is no need to upgrade. See the
[ChangeLog](ChangeLog.txt) for a full list of changes for this release.
11 October 2010
---------------
I've just released gflags 1.4. This release has only minor changes
from 1.3, including some documentation tweaks and some work to make
the library smaller. If 1.3 is working well for you, there's no
particular reason to upgrade.
4 January 2010
--------------
I've just released gflags 1.3. gflags now compiles under MSVC, and
all tests pass. I **really** never thought non-unix-y Windows folks
would want gflags, but at least some of them do.
The major news, though, is that I've separated out the python package
into its own library, [python-gflags](http://code.google.com/p/python-gflags).
If you're interested in the Python version of gflags, that's the place to
get it now.
10 September 2009
-----------------
I've just released gflags 1.2. The major change from gflags 1.1 is it
now compiles under MinGW (as well as cygwin), and all tests pass. I
never thought Windows folks would want unix-style command-line flags,
since they're so different from the Windows style, but I guess I was
wrong!
The other changes are minor, such as support for --htmlxml in the
python version of gflags.
15 April 2009
-------------
I've just released gflags 1.1. It has only minor changes fdrom gflags
1.0 (see the [ChangeLog](ChangeLog.txt) for details).
The major change is that I moved to a new system for creating .deb and .rpm files.
This allows me to create x86\_64 deb and rpm files.
In the process of moving to this new system, I noticed an
inconsistency: the tar.gz and .rpm files created libraries named
libgflags.so, but the deb file created libgoogle-gflags.so. I have
fixed the deb file to create libraries like the others. I'm no expert
in debian packaging, but I believe this has caused the package name to
change as well. Please let me know (at
[[mailto:google-gflags@googlegroups.com](mailto:google-gflags@googlegroups.com)
google-gflags@googlegroups.com]) if this causes problems for you --
especially if you know of a fix! I would be happy to change the deb
packages to add symlinks from the old library name to the new
(libgoogle-gflags.so -> libgflags.so), but that is beyond my knowledge
of how to make .debs.
If you've tried to install a .rpm or .deb and it doesn't work for you,
let me know. I'm excited to finally have 64-bit package files, but
there may still be some wrinkles in the new system to iron out.
1 October 2008
--------------
gflags 1.0rc2 was out for a few weeks without any issues, so gflags
1.0 is now released. This is much like gflags 0.9. The major change
is that the .h files have been moved from `/usr/include/google` to
`/usr/include/gflags`. While I have backwards-compatibility
forwarding headeds in place, please rewrite existing code to say
```
#include <gflags/gflags.h>
```
instead of
```
#include <google/gflags.h>
```
I've kept the default namespace to google. You can still change with
with the appropriate flag to the configure script (`./configure
--help` to see the flags). If you have feedback as to whether the
default namespace should change to gflags, which would be a
non-backwards-compatible change, send mail to
`google-gflags@googlegroups.com`!
Version 1.0 also has some neat new features, like support for bash
commandline-completion of help flags. See the [ChangeLog](ChangeLog.txt)
for more details.
If I don't hear any bad news for a few weeks, I'll release 1.0-final.

<h2> <A NAME=intro>Introduction, and Comparison to Other Commandline
Flags Libraries</A> </h2>
<p><b>Commandline flags</b> are flags that users specify on the
command line when they run an executable. In the command</p>
<pre>
fgrep -l -f /var/tmp/foo johannes brahms
</pre>
<p><code>-l</code> and <code>-f /var/tmp/foo</code> are the two
commandline flags. (<code>johannes</code> and <code>brahms</code>,
which don't start with a dash, are <b>commandline arguments</b>.)</p>
<p>Typically, an application lists what flags the user is allowed to
pass in, and what arguments they take -- in this example,
<code>-l</code> takes no argument, and <code>-f</code> takes a
string (in particular, a filename) as an argument. Users can use a
library to help parse the commandline and store the flags in some data
structure.</p>
<p>Gflags, the commandline flags library used within Google,
differs from other libraries,
such as <code>getopt()</code>, in that flag definitions can be
scattered around the source code, and not just listed in one place
such as <code>main()</code>. In practice, this means that a single
source-code file will define and use flags that are meaningful to that
file. Any application that links in that file will get the flags, and
the gflags library will automatically handle that
flag appropriately.</p>
<p>There's significant gain in flexibility, and ease of code reuse,
due to this technique. However, there is a danger that two files will
define the same flag, and then give an error when they're linked
together.</p>
<p>The rest of this document describes how to use the commandlineflag
library. It's a C++ library, so examples are in C++. However, there
is a Python port with the same functionality, and this discussion
translates directly to Python.</p>
<h2> <A NAME=download>Download and Installation</A> </h2>
<p>The gflags library can be downloaded from <A href="https://github.com/gflags/gflags">GitHub</A>.
You can clone the project using the command:</p>
<pre>
git clone https://github.com/gflags/gflags.git
</pre>
<p>Build and installation instructions are provided in the
<A href="https://github.com/gflags/gflags/blob/master/INSTALL.md">INSTALL</A> file.
The installation of the gflags package includes configuration files for popular build systems
such as <A href="https://www.freedesktop.org/wiki/Software/pkg-config/">pkg-config</A>,
<A href="#cmake">CMake</A>, and <A href="#bazel">Bazel</A>.</p>
<h2> <A name=cmake>Declare dependency on gflags with CMake</A></h2>
<p>Using gflags within a project which uses <A href="http://www.cmake.org">CMake</A> for its build system is easy.
You can either require an external installation of the gflags package and find it using CMake's find_package
command, or include the gflags project as subtree or submodule within your project's source tree and add the directory
using CMake's add_subdirectory command.
<p>To use an external gflags installation, add the following CMake code to your <code>CMakeLists.txt</code> file.</p>
<p>Find gflags installation. The <code>gflags_DIR</code> variable must be set to the &lt;prefix&gt;/lib/cmake/gflags directory
containing the gflags-config.cmake file if &lt;prefix&gt; is a non-standard location. Otherwise, CMake should find
the gflags installation automatically.</p>
<pre>
find_package(gflags REQUIRED)
</pre>
<p>To request a particular imported gflags library target to link against, use the <code>COMPONENTS</code> option of
the find_package command. For example, to force the use of the single-threaded static library, use the command</p>
<pre>
find_package(gflags COMPONENTS nothreads_static)
</pre>
<p>Note that this will raise a fatal error when the installed gflags package does not contain the requested library.
It is therefore recommended to only specify the particular component to look for if a specific library must be used.
Otherwise, the gflags-config.cmake module will choose a suitable and available library for you. By default, the
multi-threaded gflags library with shared linkage is chosen if available.</p>
<p>When the source tree of the gflags project is included as subtree or submodule in the "gflags" directory of your project,
replace the above find_package command by <code>add_subdirectory(gflags)</code>. See the top of the <code>gflags/CMakeLists.txt</code>
file for a listing of available CMake variables that can be set before this command to configure the build of the
gflags library. The default build settings are the build of a single-threaded static library which does not require
any installation of the gflags subproject products.</p>
<p>Finally, add your executable build target which uses gflags to parse the command arguments with dependency on the
imported gflags library target:</p>
<pre>
add_executable(foo main.cc)
target_link_libraries(foo gflags)
</pre>
<h2> <A name=bazel>Declare dependency on gflags with Bazel</A></h2>
<p>To use gflags within a project which uses <A href="https://bazel.build/">Bazel</A> as build tool,
add the following lines to your <code>WORKSPACE</code> file
(see also Bazel documentation of <A href="https://www.bazel.io/versions/master/docs/be/workspace.html#git_repository">git_repository</A>):
<pre>
git_repository(
name = "com_github_gflags_gflags",
commit = "&lt;INSERT COMMIT SHA HERE&gt;",
remote = "https://github.com/gflags/gflags.git",
)
bind(
name = "gflags",
actual = "@com_github_gflags_gflags//:gflags",
)
bind(
name = "gflags_nothreads",
actual = "@com_github_gflags_gflags//:gflags_nothreads",
)
</pre>
<p>You can then add <code>//external:gflags</code> to the <code>deps</code> section of a <code>cc_binary</code>
or <code>cc_library</code> rule, and <code>#include "gflags/gflags.h"</code> to include it in your source code.
This use the shared gflags library with multi-threading enabled. In order to use the single-threaded shared
gflags library, use the external dependency <code>//external:gflags_nothreads</code> instead.</p>
<p>For example, see the following <code>BUILD</code> rule of the gflags/example project:</p>
<pre>
cc_binary(
name = "foo",
srcs = ["main.cc"],
deps = ["//external:gflags"],
)
</pre>
<h2> <A name=define>DEFINE: Defining Flags In Program</A> </h2>
<p> Defining a flag is easy: just use the appropriate macro for the
type you want the flag to be, as defined at the bottom of
<code>gflags/gflags.h</code>. Here's an example file,
<code>foo.cc</code>:</p>
<pre>
#include &lt;gflags/gflags.h&gt;
DEFINE_bool(big_menu, true, "Include 'advanced' options in the menu listing");
DEFINE_string(languages, "english,french,german",
"comma-separated list of languages to offer in the 'lang' menu");
</pre>
<p><code>DEFINE_bool</code> defines a boolean flag. Here are the
types supported:</p>
<ul>
<li> <code>DEFINE_bool</code>: boolean
<li> <code>DEFINE_int32</code>: 32-bit integer
<li> <code>DEFINE_int64</code>: 64-bit integer
<li> <code>DEFINE_uint64</code>: unsigned 64-bit integer
<li> <code>DEFINE_double</code>: double
<li> <code>DEFINE_string</code>: C++ string
</ul>
<p>Note that there are no 'complex' types like lists: the "languages"
flag in our example is a list of strings, but is defined of type
"string", not "list_of_string" or similar. This is by design. We'd
rather use only simple types for the flags, and allow for complex,
arbitrary parsing routines to parse them, than to try to put the logic
inside the flags library proper.</p>
<p>All DEFINE macros take the same three arguments: the name of the
flag, its default value, and a 'help' string that describes its use.
The 'help' string is displayed when the user runs the application with
the <A HREF="#special"><code>--help</code> flag</A>.</p>
<p>You can define a flag in any source-code file in your executable.
Only define a flag once! If you want to access a flag in more than
one source file, DEFINE it in one file, and <A
HREF="#declare">DECLARE</A> it in the others. Even better, DEFINE it
in <code>foo.cc</code> and DECLARE it in <code>foo.h</code>; then
everyone who <code>#includes foo.h</code> can use the flag.</p>
<p>
Defining flags in libraries rather than in main() is powerful, but
does have some costs. One is that a library might not have a good
default value for its flags, for example if the flag holds a
filename that might not exist in some environments. To mitigate such problems,
you can use <a href="#validate">flag validators</a> to ensure prompt
notification (in the form of a crash) of an invalid flag value.
</p>
<p>Note that while most functions in this library are defined in the
<code>google</code> namespace, <code>DEFINE_foo</code> (and
<code>DECLARE_foo</code>, <A HREF="#declare">below</A>), should always
be in the global namespace.</p>
<h2> <A name=using>Accessing the Flag</A> </h2>
<p>All defined flags are available to the program as just a normal
variable, with the prefix <code>FLAGS_</code> prepended. In the above
example, the macros define two variables, <code>FLAGS_big_menu</code>
(a bool), and <code>FLAGS_languages</code> (a C++ string).</p>
<p>You can read and write to the flag just like any other
variable:</p>
<pre>
if (FLAGS_consider_made_up_languages)
FLAGS_languages += ",klingon"; // implied by --consider_made_up_languages
if (FLAGS_languages.find("finnish") != string::npos)
HandleFinnish();
</pre>
<p>You can also get and set flag values via special functions in
<code>gflags.h</code>. That's a rarer use case, though.</p>
<h2> <A name=declare>DECLARE: Using the Flag in a Different File</A> </h2>
<p>Accessing a flag in the manner of the previous section only works
if the flag was <code>DEFINE</code>-ed at the top of the file. If it
wasn't, you'll get an 'unknown variable' error.</p>
<p>The <code>DECLARE_type</code> macro is available when you want to
use a flag that's defined in another file. For instance, if I were
writing <code>bar.cc</code> but wanted to access the big_menu, flag, I
would put this near the top of <code>bar.cc</code>:</p>
<pre>
DECLARE_bool(big_menu);
</pre>
<p>This is functionally equivalent to saying <code>extern
FLAGS_big_menu</code>.</p>
<p>Note that such an extern declaration introduces a dependency
between your file and the file that defines the <code>big_menu</code>
flag: <code>foo.cc</code>, in this case. Such implicit dependencies
can be difficult to manage in large projects. For that reason we
recommend the following guideline:</p>
<blockquote>
If you DEFINE a flag in <code>foo.cc</code>, either don't DECLARE it
at all, only DECLARE it in tightly related tests, or only DECLARE
it in <code>foo.h</code>.
</blockquote>
<p>You should go the do-not-DECLARE route when the flag is only needed
by <code>foo.cc</code>, and not in any other file. If you want to
modify the value of the flag in the related test file to see if it is
functioning as expected, DECLARE it in the <code>foo_test.cc</code>
file.
<p>If the flag does span multiple files, DECLARE it in the associated
<code>.h</code> file, and make others <code>#include</code> that
<code>.h</code> file if they want to access the flag. The
<code>#include</code> will make explicit the dependency between the
two files. This causes the flag to be a global variable.</p>
<h2> <A name=validate>RegisterFlagValidator: Sanity-checking Flag Values</A> </h2>
<p>After DEFINE-ing a flag, you may optionally register a validator
function with the flag. If you do this, after the flag is parsed from
the commandline, and whenever its value is changed via a call to
<code>SetCommandLineOption()</code>, the validator function is called
with the new value as an argument. The validator function should
return 'true' if the flag value is valid, and false otherwise.
If the function returns false for the new setting of the
flag, the flag will retain its current value. If it returns false for the
default value, ParseCommandLineFlags will die.
<p>Here is an example use of this functionality:</p>
<pre>
static bool ValidatePort(const char* flagname, int32 value) {
if (value > 0 && value < 32768) // value is ok
return true;
printf("Invalid value for --%s: %d\n", flagname, (int)value);
return false;
}
DEFINE_int32(port, 0, "What port to listen on");
DEFINE_validator(port, &ValidatePort);
</pre>
<p>By doing the registration at global initialization time (right
after the DEFINE_int32), we ensure that the registration happens before
the commandline is parsed at the beginning of <code>main()</code>.</p>
<p>The above used <code>DEFINE_validator</code> macro calls the
<code>RegisterFlagValidator()</code> function which returns true if the
registration is successful. It returns false if the registration fails
because a) the first argument does not refer to a commandline flag, or
b) a different validator has already been registered for this flag.
The return value is available as global static boolean variable named
<code>&lt;flag&gt;_validator_registered</code>.</p>
<h2> <A name=together>Putting It Together: How to Set Up Flags</A> </h2>
<p>The final piece is the one that tells the executable to process the
commandline flags, and set the <code>FLAGS_*</code> variables to the
appropriate, non-default value based on what is seen on the
commandline. This is equivalent to the <code>getopt()</code> call in
the getopt library, but has much less overhead to use. In fact, it's
just a single function call:</p>
<pre>
gflags::ParseCommandLineFlags(&argc, &argv, true);
</pre>
<p>Usually, this code is at the beginning of <code>main()</code>.
<code>argc</code> and <code>argv</code> are exactly as passed in to
<code>main()</code>. This routine might modify them, which is why
pointers to them are passed in.</p>
<p>The last argument is called "remove_flags". If true, then
<code>ParseCommandLineFlags</code> removes the flags and their
arguments from <code>argv</code>, and modifies <code>argc</code>
appropriately. In this case, after the function call,
<code>argv</code> will hold only commandline arguments, and not
commandline flags.</p>
<p>If, on the other hand, <code>remove_flags</code> is false, then
<code>ParseCommandLineFlags</code> will leave argc unchanged, but will
rearrange the arguments in argv so that the flags are all at the
beginning. For example, if the input is <code>"/bin/foo" "arg1" "-q"
"arg2"</code> (which is legal but weird), the function will rearrange
<code>argv</code> so it reads <code>"/bin/foo", "-q", "arg1",
"arg2"</code>. In this case, <code>ParseCommandLineFlags</code>
returns the index into argv that holds the first commandline argument:
that is, the index past the last flag. (In this example, it would
return 2, since <code>argv[2]</code> points to <code>arg1</code>.)</p>
<p>In either case, the <code>FLAGS_*</code> variables are modified
based on what was <A HREF="#commandline">passed in on the
commandline</A>.</p>
<h2> <A name=commandline>Setting Flags on the Command Line</A> </h2>
<p>The reason you make something a flag instead of a compile-time
constant, is so users can specify a non-default value on the
commandline. Here's how they might do it for an application that
links in <code>foo.cc</code>:</p>
<pre>
app_containing_foo --nobig_menu -languages="chinese,japanese,korean" ...
</pre>
<p>This sets <code>FLAGS_big_menu = false;</code> and
<code>FLAGS_languages = "chinese,japanese,korean"</code>, when
<code>ParseCommandLineFlags</code> is run.</p>
<p>Note the atypical syntax for setting a boolean flag to false:
putting "no" in front of its name. There's a fair bit of flexibility
to how flags may be specified. Here's an example of all the ways to
specify the "languages" flag:</p>
<ul>
<li> <code>app_containing_foo --languages="chinese,japanese,korean"</code>
<li> <code>app_containing_foo -languages="chinese,japanese,korean"</code>
<li> <code>app_containing_foo --languages "chinese,japanese,korean"</code>
<li> <code>app_containing_foo -languages "chinese,japanese,korean"</code>
</ul>
<p>For boolean flags, the possibilities are slightly different:</p>
<ul>
<li> <code>app_containing_foo --big_menu</code>
<li> <code>app_containing_foo --nobig_menu</code>
<li> <code>app_containing_foo --big_menu=true</code>
<li> <code>app_containing_foo --big_menu=false</code>
</ul>
<p>(as well as the single-dash variant on all of these).</p>
<p>Despite this flexibility, we recommend using only a single form:
<code>--variable=value</code> for non-boolean flags, and
<code>--variable/--novariable</code> for boolean flags. This
consistency will make your code more readable, and is also the format
required for certain special-use cases like <A
HREF="#flagfiles">flagfiles</A>.</p>
<p>It is a fatal error to specify a flag on the commandline that has
not been DEFINED somewhere in the executable. If you need that
functionality for some reason -- say you want to use the same set of
flags for several executables, but not all of them DEFINE every flag
in your list -- you can specify <A
HREF="#special"><code>--undefok</code></A> to suppress the error.</p>
<p>As in getopt(), <code>--</code> by itself will terminate flags
processing. So in <code>foo -f1 1 -- -f2 2</code>, <code>f1</code> is
considered a flag, but <code>-f2</code> is not.</p>
<p>If a flag is specified more than once, only the last specification
is used; the others are ignored.</p>
<p>Note that flags do not have single-letter synonyms, like they do in
the getopt library, nor do we allow "combining" flags behind a
single dash, as in <code>ls -la</code>.</p>
<h2> <A name=default>Changing the Default Flag Value</A> </h2>
<p>Sometimes a flag is defined in a library, and you want to change
its default value in one application but not others. It's simple to
do this: just assign a new value to the flag in <code>main()</code>,
before calling <code>ParseCommandLineFlags()</code>:</p>
<pre>
DECLARE_bool(lib_verbose); // mylib has a lib_verbose flag, default is false
int main(int argc, char** argv) {
FLAGS_lib_verbose = true; // in my app, I want a verbose lib by default
ParseCommandLineFlags(...);
}
</pre>
<p>For this application, users can still set the flag value on the
commandline, but if they do not, the flag's value will default to
true.</p>
<h2> <A name="special">Special Flags</a> </h2>
<p>There are a few flags defined by the commandlineflags module
itself, and are available to all applications that use
commandlineflags. These fall into
three categories. First are the 'reporting' flags that, when found, cause
the application to print some information about itself and exit.</p>
<table><tr valign=top>
<td><code>--help</code></td>
<td>shows all flags from all files, sorted by file and then by name;
shows the flagname, its default value, and its help string</td>
</tr><tr valign=top>
<td><code>--helpfull</code></td>
<td>same as -help, but unambiguously asks for all flags
(in case -help changes in the future)</td>
</tr><tr valign=top>
<td><code>--helpshort</code></td>
<td>shows only flags for the file with the same name as the executable
(usually the one containing <code>main()</code>)</td>
</tr><tr valign=top>
<td><code>--helpxml</code></td>
<td>like --help, but output is in xml for easier parsing</td>
</tr><tr valign=top>
<td><code>--helpon=FILE &nbsp;</code></td>
<td>shows only flags defined in FILE.*</td>
</tr><tr valign=top>
<td><code>--helpmatch=S</code></td>
<td>shows only flags defined in *S*.*</td>
</tr><tr valign=top>
<td><code>--helppackage</code></td>
<td>shows flags defined in files in same directory as <code>main()</code></td>
</tr><tr valign=top>
<td><code>--version</code></td>
<td>prints version info for the executable</td>
</tr></table>
<p>Second are the flags that affect how other flags are parsed.</p>
<table><tr valign=top>
<td><code>--undefok=flagname,flagname,...</code></td>
<td>for those names listed as the argument to <code>--undefok</code>,
suppress the normal error-exit that occurs when
<code>--name</code> is seen on the commandline, but
<code>name</code> has not been DEFINED anywhere in the
application
</table>
<p>Third are the 'recursive' flags, that cause other flag values to be
set: <code>--fromenv</code>, <code>--tryfromenv</code>,
<code>--flagfile</code>. These are described below in more
detail.</p>
<h3> <code>--fromenv</code> </h3>
<p><code>--fromenv=foo,bar</code> says to read the values for the
<code>foo</code> and <code>bar</code> flags from the environment.
In concert with this flag, you must actually set the values in the
environment, via a line like one of the two below:</p>
<pre>
export FLAGS_foo=xxx; export FLAGS_bar=yyy # sh
setenv FLAGS_foo xxx; setenv FLAGS_bar yyy # tcsh
</pre>
<p>This is equivalent to specifying <code>--foo=xxx</code>,
<code>--bar=yyy</code> on the commandline.</p>
<p>Note it is a fatal error to say <code>--fromenv=foo</code> if
<code>foo</code> is not DEFINED somewhere in the application. (Though
you can suppress this error via <code>--undefok=foo</code>, just like
for any other flag.)</p>
<p>It is also a fatal error to say <code>--fromenv=foo</code> if
<code>FLAGS_foo</code> is not actually defined in the environment.</p>
<h3> <code>--tryfromenv</code> </h3>
<p><code>--tryfromenv</code> is exactly like <code>--fromenv</code>,
except it is <b>not</b> a fatal error to say
<code>--tryfromenv=foo</code> if <code>FLAGS_foo</code> is not
actually defined in the environment. Instead, in such cases,
<code>FLAGS_foo</code> just keeps its default value as specified in
the application.</p>
<p>Note it is still an error to say <code>--tryfromenv=foo</code> if
<code>foo</code> is not DEFINED somewhere in the application.</p>
<h3> <code>--flagfile</code> </h3>
<p><code>--flagfile=f</code> tells the commandlineflags module to read
the file <code>f</code>, and to run all the flag-assignments found in
that file as if these flags had been specified on the commandline.</p>
<p>In its simplest form, <code>f</code> should just be a list of flag
assignments, one per line. Unlike on the commandline, the equals sign
separating a flagname from its argument is <i>required</i> for
flagfiles. An example flagfile, <code>/tmp/myflags</code>:</p>
<pre>
--nobig_menus
--languages=english,french
</pre>
<p>With this flagfile, the following two lines are equivalent:<p>
<pre>
./myapp --foo --nobig_menus --languages=english,french --bar
./myapp --foo --flagfile=/tmp/myflags --bar
</pre>
<p>Note that many errors are silently suppressed in flagfiles. In
particular, unrecognized flagnames are silently ignored, as are flags
that are missing a required value (e.g., a flagfile that just says
<code>--languages</code>).</p>
<p>The general format of a flagfile is a bit more complicated than the
simple, common case above. It is: a sequence of filenames, one per
line, followed by a sequence of flags, one per line, repeated as many
times as desired. Filenames in a flagfile can use wildcards
(<code>*</code> and <code>?</code>), and the sequence of flags located
after a sequence of filenames is processed only if the current
executable's name matches one of the filenames. It is possible to
start the flagfile with a sequence of flags instead of a sequence of
filenames; if such a sequence of flags is present, these flags are
applied to the current executable no matter what it is.</p>
<p>Lines that start with a <code>#</code> are ignored as comments.
Leading whitespace is also ignored in flagfiles, as are blank
lines.</p>
<p>It is possible for a flagfile to use the <code>--flagfile</code>
flag to include another flagfile.</p>
<p>Flags are always processed in the expected order. That is,
processing begins by examining the flags specified directly on the
command line. If a flagfile is specified, its contents are processed,
and then processing continues with remaining flags from the command
line.</p>
<h2> <A name="api">The API</a> </h2>
<p>In addition to accessing <code>FLAGS_foo</code> directly, it is
possible to access the flags programmatically, through an API. It is
also possible to access information about a flag, such as its default
value and help-string. A <code>FlagSaver</code> makes it easy to
modify flags and then automatically undo the modifications later.
Finally, there are somewhat unrelated, but useful, routines to easily
access parts of <code>argv</code> outside main, including the program
name (<code>argv[0]</code>).</p>
<p>For more information about these routines, and other useful helper
methods such as <code>gflags::SetUsageMessage()</code> and
<code>gflags::SetVersionString</code>, see <code>gflags.h</code>.</p>
<h2> <A name="misc">Miscellaneous Notes</code> </h2>
<p>If your application has code like this:</p>
<pre>
#define STRIP_FLAG_HELP 1 // this must go before the #include!
#include &lt;gflags/gflags.h&gt;
</pre>
<p>we will remove the help messages from the compiled source. This can
reduce the size of the resulting binary somewhat, and may also be
useful for security reasons.</p>
<h2> <A name="issues">Issues and Feature Requests</code> </h2>
<p>Please report any issues or ideas for additional features on <A href="https://github.com/gflags/gflags/issues">GitHub</A>.
We would also like to encourage <A href="https://github.com/gflags/gflags/pulls">pull requests</A> for bug fixes and implementations of new features.</p>

// Now come the command line flag declaration/definition macros that
// will actually be used. They're kind of hairy. A major reason
// for this is initialization: we want people to be able to access
// variables in global constructors and have that not crash, even if
// their global constructor runs before the global constructor here.
// (Obviously, we can't guarantee the flags will have the correct
// default value in that case, but at least accessing them is safe.)
// The only way to do that is have flags point to a static buffer.
// So we make one, using a union to ensure proper alignment, and
// then use placement-new to actually set up the flag with the
// correct default value. In the same vein, we have to worry about
// flag access in global destructors, so FlagRegisterer has to be
// careful never to destroy the flag-values it constructs.
//
// Note that when we define a flag variable FLAGS_<name>, we also
// preemptively define a junk variable, FLAGS_no<name>. This is to
// cause a link-time error if someone tries to define 2 flags with
// names like "logging" and "nologging". We do this because a bool
// flag FLAG can be set from the command line to true with a "-FLAG"
// argument, and to false with a "-noFLAG" argument, and so this can
// potentially avert confusion.
//
// We also put flags into their own namespace. It is purposefully
// named in an opaque way that people should have trouble typing
// directly. The idea is that DEFINE puts the flag in the weird
// namespace, and DECLARE imports the flag from there into the current
// namespace. The net result is to force people to use DECLARE to get
// access to a flag, rather than saying "extern GFLAGS_DLL_DECL bool FLAGS_whatever;"
// or some such instead. We want this so we can put extra
// functionality (like sanity-checking) in DECLARE if we want, and
// make sure it is picked up everywhere.
//
// We also put the type of the variable in the namespace, so that
// people can't DECLARE_int32 something that they DEFINE_bool'd
// elsewhere.

// Bash-style command line flag completion for C++ binaries
//
// This module implements bash-style completions. It achieves this
// goal in the following broad chunks:
//
// 1) Take a to-be-completed word, and examine it for search hints
// 2) Identify all potentially matching flags
// 2a) If there are no matching flags, do nothing.
// 2b) If all matching flags share a common prefix longer than the
// completion word, output just that matching prefix
// 3) Categorize those flags to produce a rough ordering of relevence.
// 4) Potentially trim the set of flags returned to a smaller number
// that bash is happier with
// 5) Output the matching flags in groups ordered by relevence.
// 5a) Force bash to place most-relevent groups at the top of the list
// 5b) Trim most flag's descriptions to fit on a single terminal line

//
// Implement helpful bash-style command line flag completions
//
// ** Functional API:
// HandleCommandLineCompletions() should be called early during
// program startup, but after command line flag code has been
// initialized, such as the beginning of HandleCommandLineHelpFlags().
// It checks the value of the flag --tab_completion_word. If this
// flag is empty, nothing happens here. If it contains a string,
// however, then HandleCommandLineCompletions() will hijack the
// process, attempting to identify the intention behind this
// completion. Regardless of the outcome of this deduction, the
// process will be terminated, similar to --helpshort flag
// handling.
//
// ** Overview of Bash completions:
// Bash can be told to programatically determine completions for the
// current 'cursor word'. It does this by (in this case) invoking a
// command with some additional arguments identifying the command
// being executed, the word being completed, and the previous word
// (if any). Bash then expects a sequence of output lines to be
// printed to stdout. If these lines all contain a common prefix
// longer than the cursor word, bash will replace the cursor word
// with that common prefix, and display nothing. If there isn't such
// a common prefix, bash will display the lines in pages using 'more'.
//
// ** Strategy taken for command line completions:
// If we can deduce either the exact flag intended, or a common flag
// prefix, we'll output exactly that. Otherwise, if information
// must be displayed to the user, we'll take the opportunity to add
// some helpful information beyond just the flag name (specifically,
// we'll include the default flag value and as much of the flag's
// description as can fit on a single terminal line width, as specified
// by the flag --tab_completion_columns). Furthermore, we'll try to
// make bash order the output such that the most useful or relevent
// flags are the most likely to be shown at the top.
//
// ** Additional features:
// To assist in finding that one really useful flag, substring matching
// was implemented. Before pressing a <TAB> to get completion for the
// current word, you can append one or more '?' to the flag to do
// substring matching. Here's the semantics:
// --foo<TAB> Show me all flags with names prefixed by 'foo'
// --foo?<TAB> Show me all flags with 'foo' somewhere in the name
// --foo??<TAB> Same as prior case, but also search in module
// definition path for 'foo'
// --foo???<TAB> Same as prior case, but also search in flag
// descriptions for 'foo'
// Finally, we'll trim the output to a relatively small number of
// flags to keep bash quiet about the verbosity of output. If one
// really wanted to see all possible matches, appending a '+' to the
// search word will force the exhaustive list of matches to be printed.
//
// ** How to have bash accept completions from a binary:
// Bash requires that it be informed about each command that programmatic
// completion should be enabled for. Example addition to a .bashrc
// file would be (your path to gflags_completions.sh file may differ):
/*
$ complete -o bashdefault -o default -o nospace -C \
'/home/build/eng/bash/bash_completions.sh --tab_completion_columns $COLUMNS' \
time env binary_name another_binary [...]
*/
// This would allow the following to work:
// $ /path/to/binary_name --vmodule<TAB>
// Or:
// $ ./bin/path/another_binary --gfs_u<TAB>
// (etc)
//
// Sadly, it appears that bash gives no easy way to force this behavior for
// all commands. That's where the "time" in the above example comes in.
// If you haven't specifically added a command to the list of completion
// supported commands, you can still get completions by prefixing the
// entire command with "env".
// $ env /some/brand/new/binary --vmod<TAB>
// Assuming that "binary" is a newly compiled binary, this should still
// produce the expected completion output.

# This script is invoked by bash in response to a matching compspec. When
# this happens, bash calls this script using the command shown in the -C
# block of the complete entry, but also appends 3 arguments. They are:
# - The command being used for completion
# - The word being completed
# - The word preceding the completion word.
#
# Here's an example of how you might use this script:
# $ complete -o bashdefault -o default -o nospace -C \
# '/usr/local/bin/gflags_completions.sh --tab_completion_columns $COLUMNS' \
# time env binary_name another_binary [...]
# completion_word_index gets the index of the (N-1)th argument for
# this command line. completion_word gets the actual argument from
# this command line at the (N-1)th position
completion_word_index="$(($# - 1))"
completion_word="${!completion_word_index}"
# TODO(user): Replace this once gflags_completions.cc has
# a bool parameter indicating unambiguously to hijack the process for
# completion purposes.
if [ -z "$completion_word" ]; then
# Until an empty value for the completion word stops being misunderstood
# by binaries, don't actually execute the binary or the process
# won't be hijacked!
exit 0
fi
# binary_index gets the index of the command being completed (which bash
# places in the (N-2)nd position. binary gets the actual command from
# this command line at that (N-2)nd position
binary_index="$(($# - 2))"
binary="${!binary_index}"
# For completions to be universal, we may have setup the compspec to
# trigger on 'harmless pass-through' commands, like 'time' or 'env'.
# If the command being completed is one of those two, we'll need to
# identify the actual command being executed. To do this, we need
# the actual command line that the <TAB> was pressed on. Bash helpfully
# places this in the $COMP_LINE variable.
if [ "$binary" == "time" ] || [ "$binary" == "env" ]; then
# we'll assume that the first 'argument' is actually the
# binary
# TODO(user): This is not perfect - the 'env' command, for instance,
# is allowed to have options between the 'env' and 'the command to
# be executed'. For example, consider:
# $ env FOO="bar" bin/do_something --help<TAB>
# In this case, we'll mistake the FOO="bar" portion as the binary.
# Perhaps we should continuing consuming leading words until we
# either run out of words, or find a word that is a valid file
# marked as executable. I can't think of any reason this wouldn't
# work.
# Break up the 'original command line' (not this script's command line,
# rather the one the <TAB> was pressed on) and find the second word.

//
// A simple mutex wrapper, supporting locks and read-write locks.
// You should assume the locks are *not* re-entrant.
//
// This class is meant to be internal-only and should be wrapped by an
// internal namespace. Before you use this module, please give the
// name of your internal namespace for this module. Or, if you want
// to expose it, you'll want to move it to the Google namespace. We
// cannot put this class in global namespace because there can be some
// problems when we have multiple versions of Mutex in each shared object.
//
// NOTE: by default, we have #ifdef'ed out the TryLock() method.
// This is for two reasons:
// 1) TryLock() under Windows is a bit annoying (it requires a
// #define to be defined very early).
// 2) TryLock() is broken for NO_THREADS mode, at least in NDEBUG
// mode.
// If you need TryLock(), and either these two caveats are not a
// problem for you, or you're willing to work around them, then
// feel free to #define GMUTEX_TRYLOCK, or to remove the #ifdefs
// in the code below.
//
// CYGWIN NOTE: Cygwin support for rwlock seems to be buggy:
// http://www.cygwin.com/ml/cygwin/2008-12/msg00017.html
// Because of that, we might as well use windows locks for
// cygwin. They seem to be more reliable than the cygwin pthreads layer.
//
// TRICKY IMPLEMENTATION NOTE:
// This class is designed to be safe to use during
// dynamic-initialization -- that is, by global constructors that are
// run before main() starts. The issue in this case is that
// dynamic-initialization happens in an unpredictable order, and it
// could be that someone else's dynamic initializer could call a
// function that tries to acquire this mutex -- but that all happens
// before this mutex's constructor has run. (This can happen even if
// the mutex and the function that uses the mutex are in the same .cc
// file.) Basically, because Mutex does non-trivial work in its
// constructor, it's not, in the naive implementation, safe to use
// before dynamic initialization has run on it.
//
// The solution used here is to pair the actual mutex primitive with a
// bool that is set to true when the mutex is dynamically initialized.
// (Before that it's false.) Then we modify all mutex routines to
// look at the bool, and not try to lock/unlock until the bool makes
// it to true (which happens after the Mutex constructor has run.)
//
// This works because before main() starts -- particularly, during
// dynamic initialization -- there are no threads, so a) it's ok that
// the mutex operations are a no-op, since we don't need locking then
// anyway; and b) we can be quite confident our bool won't change
// state between a call to Lock() and a call to Unlock() (that would
// require a global constructor in one translation unit to call Lock()
// and another global constructor in another translation unit to call
// Unlock() later, which is pretty perverse).
//
// That said, it's tricky, and can conceivably fail; it's safest to
// avoid trying to acquire a mutex in a global constructor, if you
// can. One way it can fail is that a really smart compiler might
// initialize the bool to true at static-initialization time (too
// early) rather than at dynamic-initialization time. To discourage
// that, we set is_safe_ to true in code (not the constructor
// colon-initializer) and set it to true via a function that always
// evaluates to true, but that the compiler can't know always
// evaluates to true. This should be good enough.
//
// A related issue is code that could try to access the mutex
// after it's been destroyed in the global destructors (because
// the Mutex global destructor runs before some other global
// destructor, that tries to acquire the mutex). The way we
// deal with this is by taking a constructor arg that global
// mutexes should pass in, that causes the destructor to do no
// work. We still depend on the compiler not doing anything
// weird to a Mutex's memory after it is destroyed, but for a
// static global variable, that's pretty safe.

# Google Test #
[![Build Status](https://travis-ci.org/google/googletest.svg?branch=master)](https://travis-ci.org/google/googletest)
[![Build status](https://ci.appveyor.com/api/projects/status/4o38plt0xbo1ubc8/branch/master?svg=true)](https://ci.appveyor.com/project/GoogleTestAppVeyor/googletest/branch/master)
Welcome to **Google Test**, Google's C++ test framework!
This repository is a merger of the formerly separate GoogleTest and
GoogleMock projects. These were so closely related that it makes sense to
maintain and release them together.
Please see the project page above for more information as well as the
mailing list for questions, discussions, and development. There is
also an IRC channel on [OFTC](https://webchat.oftc.net/) (irc.oftc.net) #gtest available. Please
join us!
Getting started information for **Google Test** is available in the
[Google Test Primer](googletest/docs/Primer.md) documentation.
**Google Mock** is an extension to Google Test for writing and using C++ mock
classes. See the separate [Google Mock documentation](googlemock/README.md).
More detailed documentation for googletest (including build instructions) are
in its interior [googletest/README.md](googletest/README.md) file.
## Features ##
* An [xUnit](https://en.wikipedia.org/wiki/XUnit) test framework.
* Test discovery.
* A rich set of assertions.
* User-defined assertions.
* Death tests.
* Fatal and non-fatal failures.
* Value-parameterized tests.
* Type-parameterized tests.
* Various options for running the tests.
* XML test report generation.
## Platforms ##
Google test has been used on a variety of platforms:
* Linux
* Mac OS X
* Windows
* Cygwin
* MinGW
* Windows Mobile
* Symbian
## Who Is Using Google Test? ##
In addition to many internal projects at Google, Google Test is also used by
the following notable projects:
* The [Chromium projects](http://www.chromium.org/) (behind the Chrome
browser and Chrome OS).
* The [LLVM](http://llvm.org/) compiler.
* [Protocol Buffers](https://github.com/google/protobuf), Google's data
interchange format.
* The [OpenCV](http://opencv.org/) computer vision library.
* [tiny-dnn](https://github.com/tiny-dnn/tiny-dnn): header only, dependency-free deep learning framework in C++11.
## Related Open Source Projects ##
[GTest Runner](https://github.com/nholthaus/gtest-runner) is a Qt5 based automated test-runner and Graphical User Interface with powerful features for Windows and Linux platforms.
[Google Test UI](https://github.com/ospector/gtest-gbar) is test runner that runs
your test binary, allows you to track its progress via a progress bar, and
displays a list of test failures. Clicking on one shows failure text. Google
Test UI is written in C#.
[GTest TAP Listener](https://github.com/kinow/gtest-tap-listener) is an event
listener for Google Test that implements the
[TAP protocol](https://en.wikipedia.org/wiki/Test_Anything_Protocol) for test
result output. If your test runner understands TAP, you may find it useful.
[gtest-parallel](https://github.com/google/gtest-parallel) is a test runner that
runs tests from your binary in parallel to provide significant speed-up.
## Requirements ##
Google Test is designed to have fairly minimal requirements to build
and use with your projects, but there are some. Currently, we support
Linux, Windows, Mac OS X, and Cygwin. We will also make our best
effort to support other platforms (e.g. Solaris, AIX, and z/OS).
However, since core members of the Google Test project have no access
to these platforms, Google Test may have outstanding issues there. If
you notice any problems on your platform, please notify
[googletestframework@googlegroups.com](https://groups.google.com/forum/#!forum/googletestframework). Patches for fixing them are
even more welcome!
### Linux Requirements ###
These are the base requirements to build and use Google Test from a source
package (as described below):
* GNU-compatible Make or gmake
* POSIX-standard shell
* POSIX(-2) Regular Expressions (regex.h)
* A C++98-standard-compliant compiler
### Windows Requirements ###
* Microsoft Visual C++ 2010 or newer
### Cygwin Requirements ###
* Cygwin v1.5.25-14 or newer
### Mac OS X Requirements ###
* Mac OS X v10.4 Tiger or newer
* Xcode Developer Tools
### Requirements for Contributors ###
We welcome patches. If you plan to contribute a patch, you need to
build Google Test and its own tests from a git checkout (described
below), which has further requirements:
* [Python](https://www.python.org/) v2.3 or newer (for running some of
the tests and re-generating certain source files from templates)
* [CMake](https://cmake.org/) v2.6.4 or newer
## Regenerating Source Files ##
Some of Google Test's source files are generated from templates (not
in the C++ sense) using a script.
For example, the
file include/gtest/internal/gtest-type-util.h.pump is used to generate
gtest-type-util.h in the same directory.
You don't need to worry about regenerating the source files
unless you need to modify them. You would then modify the
corresponding `.pump` files and run the '[pump.py](googletest/scripts/pump.py)'
generator script. See the [Pump Manual](googletest/docs/PumpManual.md).
### Contributing Code ###
We welcome patches. Please read the
[Developer's Guide](googletest/docs/DevGuide.md)
for how you can contribute. In particular, make sure you have signed
the Contributor License Agreement, or we won't be able to accept the
patch.
Happy testing!

Changes for 1.7.0:
* All new improvements in Google Test 1.7.0.
* New feature: matchers DoubleNear(), FloatNear(),
NanSensitiveDoubleNear(), NanSensitiveFloatNear(),
UnorderedElementsAre(), UnorderedElementsAreArray(), WhenSorted(),
WhenSortedBy(), IsEmpty(), and SizeIs().
* Improvement: Google Mock can now be built as a DLL.
* Improvement: when compiled by a C++11 compiler, matchers AllOf()
and AnyOf() can accept an arbitrary number of matchers.
* Improvement: when compiled by a C++11 compiler, matchers
ElementsAreArray() can accept an initializer list.
* Improvement: when exceptions are enabled, a mock method with no
default action now throws instead crashing the test.
* Improvement: added class testing::StringMatchResultListener to aid
definition of composite matchers.
* Improvement: function return types used in MOCK_METHOD*() macros can
now contain unprotected commas.
* Improvement (potentially breaking): EXPECT_THAT() and ASSERT_THAT()
are now more strict in ensuring that the value type and the matcher
type are compatible, catching potential bugs in tests.
* Improvement: Pointee() now works on an optional<T>.
* Improvement: the ElementsAreArray() matcher can now take a vector or
iterator range as input, and makes a copy of its input elements
before the conversion to a Matcher.
* Improvement: the Google Mock Generator can now generate mocks for
some class templates.
* Bug fix: mock object destruction triggerred by another mock object's
destruction no longer hangs.
* Improvement: Google Mock Doctor works better with newer Clang and
GCC now.
* Compatibility fixes.
* Bug/warning fixes.
Changes for 1.6.0:
* Compilation is much faster and uses much less memory, especially
when the constructor and destructor of a mock class are moved out of
the class body.
* New matchers: Pointwise(), Each().
* New actions: ReturnPointee() and ReturnRefOfCopy().
* CMake support.
* Project files for Visual Studio 2010.
* AllOf() and AnyOf() can handle up-to 10 arguments now.
* Google Mock doctor understands Clang error messages now.
* SetArgPointee<> now accepts string literals.
* gmock_gen.py handles storage specifier macros and template return
types now.
* Compatibility fixes.
* Bug fixes and implementation clean-ups.
* Potentially incompatible changes: disables the harmful 'make install'
command in autotools.
Potentially breaking changes:
* The description string for MATCHER*() changes from Python-style
interpolation to an ordinary C++ string expression.
* SetArgumentPointee is deprecated in favor of SetArgPointee.
* Some non-essential project files for Visual Studio 2005 are removed.
Changes for 1.5.0:
* New feature: Google Mock can be safely used in multi-threaded tests
on platforms having pthreads.
* New feature: function for printing a value of arbitrary type.
* New feature: function ExplainMatchResult() for easy definition of
composite matchers.
* The new matcher API lets user-defined matchers generate custom
explanations more directly and efficiently.
* Better failure messages all around.
* NotNull() and IsNull() now work with smart pointers.
* Field() and Property() now work when the matcher argument is a pointer
passed by reference.
* Regular expression matchers on all platforms.
* Added GCC 4.0 support for Google Mock Doctor.
* Added gmock_all_test.cc for compiling most Google Mock tests
in a single file.
* Significantly cleaned up compiler warnings.
* Bug fixes, better test coverage, and implementation clean-ups.
Potentially breaking changes:
* Custom matchers defined using MatcherInterface or MakePolymorphicMatcher()
need to be updated after upgrading to Google Mock 1.5.0; matchers defined
using MATCHER or MATCHER_P* aren't affected.
* Dropped support for 'make install'.
Changes for 1.4.0 (we skipped 1.2.* and 1.3.* to match the version of
Google Test):
* Works in more environments: Symbian and minGW, Visual C++ 7.1.
* Lighter weight: comes with our own implementation of TR1 tuple (no
more dependency on Boost!).
* New feature: --gmock_catch_leaked_mocks for detecting leaked mocks.
* New feature: ACTION_TEMPLATE for defining templatized actions.
* New feature: the .After() clause for specifying expectation order.
* New feature: the .With() clause for specifying inter-argument
constraints.
* New feature: actions ReturnArg<k>(), ReturnNew<T>(...), and
DeleteArg<k>().
* New feature: matchers Key(), Pair(), Args<...>(), AllArgs(), IsNull(),
and Contains().
* New feature: utility class MockFunction<F>, useful for checkpoints, etc.
* New feature: functions Value(x, m) and SafeMatcherCast<T>(m).
* New feature: copying a mock object is rejected at compile time.
* New feature: a script for fusing all Google Mock and Google Test
source files for easy deployment.
* Improved the Google Mock doctor to diagnose more diseases.
* Improved the Google Mock generator script.
* Compatibility fixes for Mac OS X and gcc.
* Bug fixes and implementation clean-ups.

## Google Mock ##
The Google C++ mocking framework.
### Overview ###
Google's framework for writing and using C++ mock classes.
It can help you derive better designs of your system and write better tests.
It is inspired by:
* [jMock](http://www.jmock.org/),
* [EasyMock](http://www.easymock.org/), and
* [Hamcrest](http://code.google.com/p/hamcrest/),
and designed with C++'s specifics in mind.
Google mock:
* lets you create mock classes trivially using simple macros.
* supports a rich set of matchers and actions.
* handles unordered, partially ordered, or completely ordered expectations.
* is extensible by users.
We hope you find it useful!
### Features ###
* Provides a declarative syntax for defining mocks.
* Can easily define partial (hybrid) mocks, which are a cross of real
and mock objects.
* Handles functions of arbitrary types and overloaded functions.
* Comes with a rich set of matchers for validating function arguments.
* Uses an intuitive syntax for controlling the behavior of a mock.
* Does automatic verification of expectations (no record-and-replay needed).
* Allows arbitrary (partial) ordering constraints on
function calls to be expressed,.
* Lets an user extend it by defining new matchers and actions.
* Does not use exceptions.
* Is easy to learn and use.
Please see the project page above for more information as well as the
mailing list for questions, discussions, and development. There is
also an IRC channel on OFTC (irc.oftc.net) #gtest available. Please
join us!
Please note that code under [scripts/generator](scripts/generator/) is
from [cppclean](http://code.google.com/p/cppclean/) and released under
the Apache License, which is different from Google Mock's license.
## Getting Started ##
If you are new to the project, we suggest that you read the user
documentation in the following order:
* Learn the [basics](../../master/googletest/docs/Primer.md) of
Google Test, if you choose to use Google Mock with it (recommended).
* Read [Google Mock for Dummies](../../master/googlemock/docs/ForDummies.md).
* Read the instructions below on how to build Google Mock.
You can also watch Zhanyong's [talk](http://www.youtube.com/watch?v=sYpCyLI47rM) on Google Mock's usage and implementation.
Once you understand the basics, check out the rest of the docs:
* [CheatSheet](../../master/googlemock/docs/CheatSheet.md) - all the commonly used stuff
at a glance.
* [CookBook](../../master/googlemock/docs/CookBook.md) - recipes for getting things done,
including advanced techniques.
If you need help, please check the
[KnownIssues](docs/KnownIssues.md) and
[FrequentlyAskedQuestions](docs/FrequentlyAskedQuestions.md) before
posting a question on the
[discussion group](http://groups.google.com/group/googlemock).
### Using Google Mock Without Google Test ###
Google Mock is not a testing framework itself. Instead, it needs a
testing framework for writing tests. Google Mock works seamlessly
with [Google Test](http://code.google.com/p/googletest/), but
you can also use it with [any C++ testing framework](../../master/googlemock/docs/ForDummies.md#using-google-mock-with-any-testing-framework).
### Requirements for End Users ###
Google Mock is implemented on top of [Google Test](
http://github.com/google/googletest/), and depends on it.
You must use the bundled version of Google Test when using Google Mock.
You can also easily configure Google Mock to work with another testing
framework, although it will still need Google Test. Please read
["Using_Google_Mock_with_Any_Testing_Framework"](
../../master/googlemock/docs/ForDummies.md#using-google-mock-with-any-testing-framework)
for instructions.
Google Mock depends on advanced C++ features and thus requires a more
modern compiler. The following are needed to use Google Mock:
#### Linux Requirements ####
* GNU-compatible Make or "gmake"
* POSIX-standard shell
* POSIX(-2) Regular Expressions (regex.h)
* C++98-standard-compliant compiler (e.g. GCC 3.4 or newer)
#### Windows Requirements ####
* Microsoft Visual C++ 8.0 SP1 or newer
#### Mac OS X Requirements ####
* Mac OS X 10.4 Tiger or newer
* Developer Tools Installed
### Requirements for Contributors ###
We welcome patches. If you plan to contribute a patch, you need to
build Google Mock and its tests, which has further requirements:
* Automake version 1.9 or newer
* Autoconf version 2.59 or newer
* Libtool / Libtoolize
* Python version 2.3 or newer (for running some of the tests and
re-generating certain source files from templates)
### Building Google Mock ###
#### Using CMake ####
If you have CMake available, it is recommended that you follow the
[build instructions][gtest_cmakebuild]
as described for Google Test.
If are using Google Mock with an
existing CMake project, the section
[Incorporating Into An Existing CMake Project][gtest_incorpcmake]
may be of particular interest.
To make it work for Google Mock you will need to change
target_link_libraries(example gtest_main)
to
target_link_libraries(example gmock_main)
This works because `gmock_main` library is compiled with Google Test.
However, it does not automatically add Google Test includes.
Therefore you will also have to change
if (CMAKE_VERSION VERSION_LESS 2.8.11)
include_directories("${gtest_SOURCE_DIR}/include")
endif()
to
if (CMAKE_VERSION VERSION_LESS 2.8.11)
include_directories(BEFORE SYSTEM
"${gtest_SOURCE_DIR}/include" "${gmock_SOURCE_DIR}/include")
else()
target_include_directories(gmock_main SYSTEM BEFORE INTERFACE
"${gtest_SOURCE_DIR}/include" "${gmock_SOURCE_DIR}/include")
endif()
This will addtionally mark Google Mock includes as system, which will
silence compiler warnings when compiling your tests using clang with
`-Wpedantic -Wall -Wextra -Wconversion`.
#### Preparing to Build (Unix only) ####
If you are using a Unix system and plan to use the GNU Autotools build
system to build Google Mock (described below), you'll need to
configure it now.
To prepare the Autotools build system:
cd googlemock
autoreconf -fvi
To build Google Mock and your tests that use it, you need to tell your
build system where to find its headers and source files. The exact
way to do it depends on which build system you use, and is usually
straightforward.
This section shows how you can integrate Google Mock into your
existing build system.
Suppose you put Google Mock in directory `${GMOCK_DIR}` and Google Test
in `${GTEST_DIR}` (the latter is `${GMOCK_DIR}/gtest` by default). To
build Google Mock, create a library build target (or a project as
called by Visual Studio and Xcode) to compile
${GTEST_DIR}/src/gtest-all.cc and ${GMOCK_DIR}/src/gmock-all.cc
with
${GTEST_DIR}/include and ${GMOCK_DIR}/include
in the system header search path, and
${GTEST_DIR} and ${GMOCK_DIR}
in the normal header search path. Assuming a Linux-like system and gcc,
something like the following will do:
g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \
-isystem ${GMOCK_DIR}/include -I${GMOCK_DIR} \
-pthread -c ${GTEST_DIR}/src/gtest-all.cc
g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \
-isystem ${GMOCK_DIR}/include -I${GMOCK_DIR} \
-pthread -c ${GMOCK_DIR}/src/gmock-all.cc
ar -rv libgmock.a gtest-all.o gmock-all.o
(We need -pthread as Google Test and Google Mock use threads.)
Next, you should compile your test source file with
${GTEST\_DIR}/include and ${GMOCK\_DIR}/include in the header search
path, and link it with gmock and any other necessary libraries:
g++ -isystem ${GTEST_DIR}/include -isystem ${GMOCK_DIR}/include \
-pthread path/to/your_test.cc libgmock.a -o your_test
As an example, the make/ directory contains a Makefile that you can
use to build Google Mock on systems where GNU make is available
(e.g. Linux, Mac OS X, and Cygwin). It doesn't try to build Google
Mock's own tests. Instead, it just builds the Google Mock library and
a sample test. You can use it as a starting point for your own build
script.
If the default settings are correct for your environment, the
following commands should succeed:
cd ${GMOCK_DIR}/make
make
./gmock_test
If you see errors, try to tweak the contents of
[make/Makefile](make/Makefile) to make them go away.
### Windows ###
The msvc/2005 directory contains VC++ 2005 projects and the msvc/2010
directory contains VC++ 2010 projects for building Google Mock and
selected tests.
Change to the appropriate directory and run "msbuild gmock.sln" to
build the library and tests (or open the gmock.sln in the MSVC IDE).
If you want to create your own project to use with Google Mock, you'll
have to configure it to use the `gmock_config` propety sheet. For that:
* Open the Property Manager window (View | Other Windows | Property Manager)
* Right-click on your project and select "Add Existing Property Sheet..."
* Navigate to `gmock_config.vsprops` or `gmock_config.props` and select it.
* In Project Properties | Configuration Properties | General | Additional
Include Directories, type <path to Google Mock>/include.
### Tweaking Google Mock ###
Google Mock can be used in diverse environments. The default
configuration may not work (or may not work well) out of the box in
some environments. However, you can easily tweak Google Mock by
defining control macros on the compiler command line. Generally,
these macros are named like `GTEST_XYZ` and you define them to either 1
or 0 to enable or disable a certain feature.
We list the most frequently used macros below. For a complete list,
see file [${GTEST\_DIR}/include/gtest/internal/gtest-port.h](
../googletest/include/gtest/internal/gtest-port.h).
### Choosing a TR1 Tuple Library ###
Google Mock uses the C++ Technical Report 1 (TR1) tuple library
heavily. Unfortunately TR1 tuple is not yet widely available with all
compilers. The good news is that Google Test 1.4.0+ implements a
subset of TR1 tuple that's enough for Google Mock's need. Google Mock
will automatically use that implementation when the compiler doesn't
provide TR1 tuple.
Usually you don't need to care about which tuple library Google Test
and Google Mock use. However, if your project already uses TR1 tuple,
you need to tell Google Test and Google Mock to use the same TR1 tuple
library the rest of your project uses, or the two tuple
implementations will clash. To do that, add
-DGTEST_USE_OWN_TR1_TUPLE=0
to the compiler flags while compiling Google Test, Google Mock, and
your tests. If you want to force Google Test and Google Mock to use
their own tuple library, just add
-DGTEST_USE_OWN_TR1_TUPLE=1
to the compiler flags instead.
If you want to use Boost's TR1 tuple library with Google Mock, please
refer to the Boost website (http://www.boost.org/) for how to obtain
it and set it up.
### As a Shared Library (DLL) ###
Google Mock is compact, so most users can build and link it as a static
library for the simplicity. Google Mock can be used as a DLL, but the
same DLL must contain Google Test as well. See
[Google Test's README][gtest_readme]
for instructions on how to set up necessary compiler settings.
### Tweaking Google Mock ###
Most of Google Test's control macros apply to Google Mock as well.
Please see [Google Test's README][gtest_readme] for how to tweak them.
### Upgrading from an Earlier Version ###
We strive to keep Google Mock releases backward compatible.
Sometimes, though, we have to make some breaking changes for the
users' long-term benefits. This section describes what you'll need to
do if you are upgrading from an earlier version of Google Mock.
#### Upgrading from 1.1.0 or Earlier ####
You may need to explicitly enable or disable Google Test's own TR1
tuple library. See the instructions in section "[Choosing a TR1 Tuple
Library](../googletest/#choosing-a-tr1-tuple-library)".
#### Upgrading from 1.4.0 or Earlier ####
On platforms where the pthread library is available, Google Test and
Google Mock use it in order to be thread-safe. For this to work, you
may need to tweak your compiler and/or linker flags. Please see the
"[Multi-threaded Tests](../googletest#multi-threaded-tests
)" section in file Google Test's README for what you may need to do.
If you have custom matchers defined using `MatcherInterface` or
`MakePolymorphicMatcher()`, you'll need to update their definitions to
use the new matcher API (
[monomorphic](http://code.google.com/p/googlemock/wiki/CookBook#Writing_New_Monomorphic_Matchers),
[polymorphic](http://code.google.com/p/googlemock/wiki/CookBook#Writing_New_Polymorphic_Matchers)).
Matchers defined using `MATCHER()` or `MATCHER_P*()` aren't affected.
### Developing Google Mock ###
This section discusses how to make your own changes to Google Mock.
#### Testing Google Mock Itself ####
To make sure your changes work as intended and don't break existing
functionality, you'll want to compile and run Google Test's own tests.
For that you'll need Autotools. First, make sure you have followed
the instructions above to configure Google Mock.
Then, create a build output directory and enter it. Next,
${GMOCK_DIR}/configure # try --help for more info
Once you have successfully configured Google Mock, the build steps are
standard for GNU-style OSS packages.
make # Standard makefile following GNU conventions
make check # Builds and runs all tests - all should pass.
Note that when building your project against Google Mock, you are building
against Google Test as well. There is no need to configure Google Test
separately.

# Defining a Mock Class #
## Mocking a Normal Class ##
Given
```
class Foo {
...
virtual ~Foo();
virtual int GetSize() const = 0;
virtual string Describe(const char* name) = 0;
virtual string Describe(int type) = 0;
virtual bool Process(Bar elem, int count) = 0;
};
```
(note that `~Foo()` **must** be virtual) we can define its mock as
```
#include "gmock/gmock.h"
class MockFoo : public Foo {
MOCK_CONST_METHOD0(GetSize, int());
MOCK_METHOD1(Describe, string(const char* name));
MOCK_METHOD1(Describe, string(int type));
MOCK_METHOD2(Process, bool(Bar elem, int count));
};
```
To create a "nice" mock object which ignores all uninteresting calls,
or a "strict" mock object, which treats them as failures:
```
NiceMock<MockFoo> nice_foo; // The type is a subclass of MockFoo.
StrictMock<MockFoo> strict_foo; // The type is a subclass of MockFoo.
```
## Mocking a Class Template ##
To mock
```
template <typename Elem>
class StackInterface {
public:
...
virtual ~StackInterface();
virtual int GetSize() const = 0;
virtual void Push(const Elem& x) = 0;
};
```
(note that `~StackInterface()` **must** be virtual) just append `_T` to the `MOCK_*` macros:
```
template <typename Elem>
class MockStack : public StackInterface<Elem> {
public:
...
MOCK_CONST_METHOD0_T(GetSize, int());
MOCK_METHOD1_T(Push, void(const Elem& x));
};
```
## Specifying Calling Conventions for Mock Functions ##
If your mock function doesn't use the default calling convention, you
can specify it by appending `_WITH_CALLTYPE` to any of the macros
described in the previous two sections and supplying the calling
convention as the first argument to the macro. For example,
```
MOCK_METHOD_1_WITH_CALLTYPE(STDMETHODCALLTYPE, Foo, bool(int n));
MOCK_CONST_METHOD2_WITH_CALLTYPE(STDMETHODCALLTYPE, Bar, int(double x, double y));
```
where `STDMETHODCALLTYPE` is defined by `<objbase.h>` on Windows.
# Using Mocks in Tests #
The typical flow is:
1. Import the Google Mock names you need to use. All Google Mock names are in the `testing` namespace unless they are macros or otherwise noted.
1. Create the mock objects.
1. Optionally, set the default actions of the mock objects.
1. Set your expectations on the mock objects (How will they be called? What wil they do?).
1. Exercise code that uses the mock objects; if necessary, check the result using [Google Test](../../googletest/) assertions.
1. When a mock objects is destructed, Google Mock automatically verifies that all expectations on it have been satisfied.
Here is an example:
```
using ::testing::Return; // #1
TEST(BarTest, DoesThis) {
MockFoo foo; // #2
ON_CALL(foo, GetSize()) // #3
.WillByDefault(Return(1));
// ... other default actions ...
EXPECT_CALL(foo, Describe(5)) // #4
.Times(3)
.WillRepeatedly(Return("Category 5"));
// ... other expectations ...
EXPECT_EQ("good", MyProductionFunction(&foo)); // #5
} // #6
```
# Setting Default Actions #
Google Mock has a **built-in default action** for any function that
returns `void`, `bool`, a numeric value, or a pointer.
To customize the default action for functions with return type `T` globally:
```
using ::testing::DefaultValue;
// Sets the default value to be returned. T must be CopyConstructible.
DefaultValue<T>::Set(value);
// Sets a factory. Will be invoked on demand. T must be MoveConstructible.
// T MakeT();
DefaultValue<T>::SetFactory(&MakeT);
// ... use the mocks ...
// Resets the default value.
DefaultValue<T>::Clear();
```
To customize the default action for a particular method, use `ON_CALL()`:
```
ON_CALL(mock_object, method(matchers))
.With(multi_argument_matcher) ?
.WillByDefault(action);
```
# Setting Expectations #
`EXPECT_CALL()` sets **expectations** on a mock method (How will it be
called? What will it do?):
```
EXPECT_CALL(mock_object, method(matchers))
.With(multi_argument_matcher) ?
.Times(cardinality) ?
.InSequence(sequences) *
.After(expectations) *
.WillOnce(action) *
.WillRepeatedly(action) ?
.RetiresOnSaturation(); ?
```
If `Times()` is omitted, the cardinality is assumed to be:
* `Times(1)` when there is neither `WillOnce()` nor `WillRepeatedly()`;
* `Times(n)` when there are `n WillOnce()`s but no `WillRepeatedly()`, where `n` >= 1; or
* `Times(AtLeast(n))` when there are `n WillOnce()`s and a `WillRepeatedly()`, where `n` >= 0.
A method with no `EXPECT_CALL()` is free to be invoked _any number of times_, and the default action will be taken each time.
# Matchers #
A **matcher** matches a _single_ argument. You can use it inside
`ON_CALL()` or `EXPECT_CALL()`, or use it to validate a value
directly:
| `EXPECT_THAT(value, matcher)` | Asserts that `value` matches `matcher`. |
|:------------------------------|:----------------------------------------|
| `ASSERT_THAT(value, matcher)` | The same as `EXPECT_THAT(value, matcher)`, except that it generates a **fatal** failure. |
Built-in matchers (where `argument` is the function argument) are
divided into several categories:
## Wildcard ##
|`_`|`argument` can be any value of the correct type.|
|:--|:-----------------------------------------------|
|`A<type>()` or `An<type>()`|`argument` can be any value of type `type`. |
## Generic Comparison ##
|`Eq(value)` or `value`|`argument == value`|
|:---------------------|:------------------|
|`Ge(value)` |`argument >= value`|
|`Gt(value)` |`argument > value` |
|`Le(value)` |`argument <= value`|
|`Lt(value)` |`argument < value` |
|`Ne(value)` |`argument != value`|
|`IsNull()` |`argument` is a `NULL` pointer (raw or smart).|
|`NotNull()` |`argument` is a non-null pointer (raw or smart).|
|`Ref(variable)` |`argument` is a reference to `variable`.|
|`TypedEq<type>(value)`|`argument` has type `type` and is equal to `value`. You may need to use this instead of `Eq(value)` when the mock function is overloaded.|
Except `Ref()`, these matchers make a _copy_ of `value` in case it's
modified or destructed later. If the compiler complains that `value`
doesn't have a public copy constructor, try wrap it in `ByRef()`,
e.g. `Eq(ByRef(non_copyable_value))`. If you do that, make sure
`non_copyable_value` is not changed afterwards, or the meaning of your
matcher will be changed.
## Floating-Point Matchers ##
|`DoubleEq(a_double)`|`argument` is a `double` value approximately equal to `a_double`, treating two NaNs as unequal.|
|:-------------------|:----------------------------------------------------------------------------------------------|
|`FloatEq(a_float)` |`argument` is a `float` value approximately equal to `a_float`, treating two NaNs as unequal. |
|`NanSensitiveDoubleEq(a_double)`|`argument` is a `double` value approximately equal to `a_double`, treating two NaNs as equal. |
|`NanSensitiveFloatEq(a_float)`|`argument` is a `float` value approximately equal to `a_float`, treating two NaNs as equal. |
The above matchers use ULP-based comparison (the same as used in
[Google Test](../../googletest/)). They
automatically pick a reasonable error bound based on the absolute
value of the expected value. `DoubleEq()` and `FloatEq()` conform to
the IEEE standard, which requires comparing two NaNs for equality to
return false. The `NanSensitive*` version instead treats two NaNs as
equal, which is often what a user wants.
|`DoubleNear(a_double, max_abs_error)`|`argument` is a `double` value close to `a_double` (absolute error <= `max_abs_error`), treating two NaNs as unequal.|
|:------------------------------------|:--------------------------------------------------------------------------------------------------------------------|
|`FloatNear(a_float, max_abs_error)` |`argument` is a `float` value close to `a_float` (absolute error <= `max_abs_error`), treating two NaNs as unequal. |
|`NanSensitiveDoubleNear(a_double, max_abs_error)`|`argument` is a `double` value close to `a_double` (absolute error <= `max_abs_error`), treating two NaNs as equal. |
|`NanSensitiveFloatNear(a_float, max_abs_error)`|`argument` is a `float` value close to `a_float` (absolute error <= `max_abs_error`), treating two NaNs as equal. |
## String Matchers ##
The `argument` can be either a C string or a C++ string object:
|`ContainsRegex(string)`|`argument` matches the given regular expression.|
|:----------------------|:-----------------------------------------------|
|`EndsWith(suffix)` |`argument` ends with string `suffix`. |
|`HasSubstr(string)` |`argument` contains `string` as a sub-string. |
|`MatchesRegex(string)` |`argument` matches the given regular expression with the match starting at the first character and ending at the last character.|
|`StartsWith(prefix)` |`argument` starts with string `prefix`. |
|`StrCaseEq(string)` |`argument` is equal to `string`, ignoring case. |
|`StrCaseNe(string)` |`argument` is not equal to `string`, ignoring case.|
|`StrEq(string)` |`argument` is equal to `string`. |
|`StrNe(string)` |`argument` is not equal to `string`. |
`ContainsRegex()` and `MatchesRegex()` use the regular expression
syntax defined
[here](../../googletest/docs/AdvancedGuide.md#regular-expression-syntax).
`StrCaseEq()`, `StrCaseNe()`, `StrEq()`, and `StrNe()` work for wide
strings as well.
## Container Matchers ##
Most STL-style containers support `==`, so you can use
`Eq(expected_container)` or simply `expected_container` to match a
container exactly. If you want to write the elements in-line,
match them more flexibly, or get more informative messages, you can use:
| `ContainerEq(container)` | The same as `Eq(container)` except that the failure message also includes which elements are in one container but not the other. |
|:-------------------------|:---------------------------------------------------------------------------------------------------------------------------------|
| `Contains(e)` | `argument` contains an element that matches `e`, which can be either a value or a matcher. |
| `Each(e)` | `argument` is a container where _every_ element matches `e`, which can be either a value or a matcher. |
| `ElementsAre(e0, e1, ..., en)` | `argument` has `n + 1` elements, where the i-th element matches `ei`, which can be a value or a matcher. 0 to 10 arguments are allowed. |
| `ElementsAreArray({ e0, e1, ..., en })`, `ElementsAreArray(array)`, or `ElementsAreArray(array, count)` | The same as `ElementsAre()` except that the expected element values/matchers come from an initializer list, STL-style container, or C-style array. |
| `IsEmpty()` | `argument` is an empty container (`container.empty()`). |
| `Pointwise(m, container)` | `argument` contains the same number of elements as in `container`, and for all i, (the i-th element in `argument`, the i-th element in `container`) match `m`, which is a matcher on 2-tuples. E.g. `Pointwise(Le(), upper_bounds)` verifies that each element in `argument` doesn't exceed the corresponding element in `upper_bounds`. See more detail below. |
| `SizeIs(m)` | `argument` is a container whose size matches `m`. E.g. `SizeIs(2)` or `SizeIs(Lt(2))`. |
| `UnorderedElementsAre(e0, e1, ..., en)` | `argument` has `n + 1` elements, and under some permutation each element matches an `ei` (for a different `i`), which can be a value or a matcher. 0 to 10 arguments are allowed. |
| `UnorderedElementsAreArray({ e0, e1, ..., en })`, `UnorderedElementsAreArray(array)`, or `UnorderedElementsAreArray(array, count)` | The same as `UnorderedElementsAre()` except that the expected element values/matchers come from an initializer list, STL-style container, or C-style array. |
| `WhenSorted(m)` | When `argument` is sorted using the `<` operator, it matches container matcher `m`. E.g. `WhenSorted(UnorderedElementsAre(1, 2, 3))` verifies that `argument` contains elements `1`, `2`, and `3`, ignoring order. |
| `WhenSortedBy(comparator, m)` | The same as `WhenSorted(m)`, except that the given comparator instead of `<` is used to sort `argument`. E.g. `WhenSortedBy(std::greater<int>(), ElementsAre(3, 2, 1))`. |
Notes:
* These matchers can also match:
1. a native array passed by reference (e.g. in `Foo(const int (&a)[5])`), and
1. an array passed as a pointer and a count (e.g. in `Bar(const T* buffer, int len)` -- see [Multi-argument Matchers](#Multiargument_Matchers.md)).
* The array being matched may be multi-dimensional (i.e. its elements can be arrays).
* `m` in `Pointwise(m, ...)` should be a matcher for `::testing::tuple<T, U>` where `T` and `U` are the element type of the actual container and the expected container, respectively. For example, to compare two `Foo` containers where `Foo` doesn't support `operator==` but has an `Equals()` method, one might write:
```
using ::testing::get;
MATCHER(FooEq, "") {
return get<0>(arg).Equals(get<1>(arg));
}
...
EXPECT_THAT(actual_foos, Pointwise(FooEq(), expected_foos));
```
## Member Matchers ##
|`Field(&class::field, m)`|`argument.field` (or `argument->field` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_.|
|:------------------------|:---------------------------------------------------------------------------------------------------------------------------------------------|
|`Key(e)` |`argument.first` matches `e`, which can be either a value or a matcher. E.g. `Contains(Key(Le(5)))` can verify that a `map` contains a key `<= 5`.|
|`Pair(m1, m2)` |`argument` is an `std::pair` whose `first` field matches `m1` and `second` field matches `m2`. |
|`Property(&class::property, m)`|`argument.property()` (or `argument->property()` when `argument` is a plain pointer) matches matcher `m`, where `argument` is an object of type _class_.|
## Matching the Result of a Function or Functor ##
|`ResultOf(f, m)`|`f(argument)` matches matcher `m`, where `f` is a function or functor.|
|:---------------|:---------------------------------------------------------------------|
## Pointer Matchers ##
|`Pointee(m)`|`argument` (either a smart pointer or a raw pointer) points to a value that matches matcher `m`.|
|:-----------|:-----------------------------------------------------------------------------------------------|
|`WhenDynamicCastTo<T>(m)`| when `argument` is passed through `dynamic_cast<T>()`, it matches matcher `m`. |
## Multiargument Matchers ##
Technically, all matchers match a _single_ value. A "multi-argument"
matcher is just one that matches a _tuple_. The following matchers can
be used to match a tuple `(x, y)`:
|`Eq()`|`x == y`|
|:-----|:-------|
|`Ge()`|`x >= y`|
|`Gt()`|`x > y` |
|`Le()`|`x <= y`|
|`Lt()`|`x < y` |
|`Ne()`|`x != y`|
You can use the following selectors to pick a subset of the arguments
(or reorder them) to participate in the matching:
|`AllArgs(m)`|Equivalent to `m`. Useful as syntactic sugar in `.With(AllArgs(m))`.|
|:-----------|:-------------------------------------------------------------------|
|`Args<N1, N2, ..., Nk>(m)`|The tuple of the `k` selected (using 0-based indices) arguments matches `m`, e.g. `Args<1, 2>(Eq())`.|
## Composite Matchers ##
You can make a matcher from one or more other matchers:
|`AllOf(m1, m2, ..., mn)`|`argument` matches all of the matchers `m1` to `mn`.|
|:-----------------------|:---------------------------------------------------|
|`AnyOf(m1, m2, ..., mn)`|`argument` matches at least one of the matchers `m1` to `mn`.|
|`Not(m)` |`argument` doesn't match matcher `m`. |
## Adapters for Matchers ##
|`MatcherCast<T>(m)`|casts matcher `m` to type `Matcher<T>`.|
|:------------------|:--------------------------------------|
|`SafeMatcherCast<T>(m)`| [safely casts](CookBook.md#casting-matchers) matcher `m` to type `Matcher<T>`. |
|`Truly(predicate)` |`predicate(argument)` returns something considered by C++ to be true, where `predicate` is a function or functor.|
## Matchers as Predicates ##
|`Matches(m)(value)`|evaluates to `true` if `value` matches `m`. You can use `Matches(m)` alone as a unary functor.|
|:------------------|:---------------------------------------------------------------------------------------------|
|`ExplainMatchResult(m, value, result_listener)`|evaluates to `true` if `value` matches `m`, explaining the result to `result_listener`. |
|`Value(value, m)` |evaluates to `true` if `value` matches `m`. |
## Defining Matchers ##
| `MATCHER(IsEven, "") { return (arg % 2) == 0; }` | Defines a matcher `IsEven()` to match an even number. |
|:-------------------------------------------------|:------------------------------------------------------|
| `MATCHER_P(IsDivisibleBy, n, "") { *result_listener << "where the remainder is " << (arg % n); return (arg % n) == 0; }` | Defines a macher `IsDivisibleBy(n)` to match a number divisible by `n`. |
| `MATCHER_P2(IsBetween, a, b, std::string(negation ? "isn't" : "is") + " between " + PrintToString(a) + " and " + PrintToString(b)) { return a <= arg && arg <= b; }` | Defines a matcher `IsBetween(a, b)` to match a value in the range [`a`, `b`]. |
**Notes:**
1. The `MATCHER*` macros cannot be used inside a function or class.
1. The matcher body must be _purely functional_ (i.e. it cannot have any side effect, and the result must not depend on anything other than the value being matched and the matcher parameters).
1. You can use `PrintToString(x)` to convert a value `x` of any type to a string.
## Matchers as Test Assertions ##
|`ASSERT_THAT(expression, m)`|Generates a [fatal failure](../../googletest/docs/Primer.md#assertions) if the value of `expression` doesn't match matcher `m`.|
|:---------------------------|:----------------------------------------------------------------------------------------------------------------------------------------------|
|`EXPECT_THAT(expression, m)`|Generates a non-fatal failure if the value of `expression` doesn't match matcher `m`. |
# Actions #
**Actions** specify what a mock function should do when invoked.
## Returning a Value ##
|`Return()`|Return from a `void` mock function.|
|:---------|:----------------------------------|
|`Return(value)`|Return `value`. If the type of `value` is different to the mock function's return type, `value` is converted to the latter type <i>at the time the expectation is set</i>, not when the action is executed.|
|`ReturnArg<N>()`|Return the `N`-th (0-based) argument.|
|`ReturnNew<T>(a1, ..., ak)`|Return `new T(a1, ..., ak)`; a different object is created each time.|
|`ReturnNull()`|Return a null pointer. |
|`ReturnPointee(ptr)`|Return the value pointed to by `ptr`.|
|`ReturnRef(variable)`|Return a reference to `variable`. |
|`ReturnRefOfCopy(value)`|Return a reference to a copy of `value`; the copy lives as long as the action.|
## Side Effects ##
|`Assign(&variable, value)`|Assign `value` to variable.|
|:-------------------------|:--------------------------|
| `DeleteArg<N>()` | Delete the `N`-th (0-based) argument, which must be a pointer. |
| `SaveArg<N>(pointer)` | Save the `N`-th (0-based) argument to `*pointer`. |
| `SaveArgPointee<N>(pointer)` | Save the value pointed to by the `N`-th (0-based) argument to `*pointer`. |
| `SetArgReferee<N>(value)` | Assign value to the variable referenced by the `N`-th (0-based) argument. |
|`SetArgPointee<N>(value)` |Assign `value` to the variable pointed by the `N`-th (0-based) argument.|
|`SetArgumentPointee<N>(value)`|Same as `SetArgPointee<N>(value)`. Deprecated. Will be removed in v1.7.0.|
|`SetArrayArgument<N>(first, last)`|Copies the elements in source range [`first`, `last`) to the array pointed to by the `N`-th (0-based) argument, which can be either a pointer or an iterator. The action does not take ownership of the elements in the source range.|
|`SetErrnoAndReturn(error, value)`|Set `errno` to `error` and return `value`.|
|`Throw(exception)` |Throws the given exception, which can be any copyable value. Available since v1.1.0.|
## Using a Function or a Functor as an Action ##
|`Invoke(f)`|Invoke `f` with the arguments passed to the mock function, where `f` can be a global/static function or a functor.|
|:----------|:-----------------------------------------------------------------------------------------------------------------|
|`Invoke(object_pointer, &class::method)`|Invoke the {method on the object with the arguments passed to the mock function. |
|`InvokeWithoutArgs(f)`|Invoke `f`, which can be a global/static function or a functor. `f` must take no arguments. |
|`InvokeWithoutArgs(object_pointer, &class::method)`|Invoke the method on the object, which takes no arguments. |
|`InvokeArgument<N>(arg1, arg2, ..., argk)`|Invoke the mock function's `N`-th (0-based) argument, which must be a function or a functor, with the `k` arguments.|
The return value of the invoked function is used as the return value
of the action.
When defining a function or functor to be used with `Invoke*()`, you can declare any unused parameters as `Unused`:
```
double Distance(Unused, double x, double y) { return sqrt(x*x + y*y); }
...
EXPECT_CALL(mock, Foo("Hi", _, _)).WillOnce(Invoke(Distance));
```
In `InvokeArgument<N>(...)`, if an argument needs to be passed by reference, wrap it inside `ByRef()`. For example,
```
InvokeArgument<2>(5, string("Hi"), ByRef(foo))
```
calls the mock function's #2 argument, passing to it `5` and `string("Hi")` by value, and `foo` by reference.
## Default Action ##
|`DoDefault()`|Do the default action (specified by `ON_CALL()` or the built-in one).|
|:------------|:--------------------------------------------------------------------|
**Note:** due to technical reasons, `DoDefault()` cannot be used inside a composite action - trying to do so will result in a run-time error.
## Composite Actions ##
|`DoAll(a1, a2, ..., an)`|Do all actions `a1` to `an` and return the result of `an` in each invocation. The first `n - 1` sub-actions must return void. |
|:-----------------------|:-----------------------------------------------------------------------------------------------------------------------------|
|`IgnoreResult(a)` |Perform action `a` and ignore its result. `a` must not return void. |
|`WithArg<N>(a)` |Pass the `N`-th (0-based) argument of the mock function to action `a` and perform it. |
|`WithArgs<N1, N2, ..., Nk>(a)`|Pass the selected (0-based) arguments of the mock function to action `a` and perform it. |
|`WithoutArgs(a)` |Perform action `a` without any arguments. |
## Defining Actions ##
| `ACTION(Sum) { return arg0 + arg1; }` | Defines an action `Sum()` to return the sum of the mock function's argument #0 and #1. |
|:--------------------------------------|:---------------------------------------------------------------------------------------|
| `ACTION_P(Plus, n) { return arg0 + n; }` | Defines an action `Plus(n)` to return the sum of the mock function's argument #0 and `n`. |
| `ACTION_Pk(Foo, p1, ..., pk) { statements; }` | Defines a parameterized action `Foo(p1, ..., pk)` to execute the given `statements`. |
The `ACTION*` macros cannot be used inside a function or class.
# Cardinalities #
These are used in `Times()` to specify how many times a mock function will be called:
|`AnyNumber()`|The function can be called any number of times.|
|:------------|:----------------------------------------------|
|`AtLeast(n)` |The call is expected at least `n` times. |
|`AtMost(n)` |The call is expected at most `n` times. |
|`Between(m, n)`|The call is expected between `m` and `n` (inclusive) times.|
|`Exactly(n) or n`|The call is expected exactly `n` times. In particular, the call should never happen when `n` is 0.|
# Expectation Order #
By default, the expectations can be matched in _any_ order. If some
or all expectations must be matched in a given order, there are two
ways to specify it. They can be used either independently or
together.
## The After Clause ##
```
using ::testing::Expectation;
...
Expectation init_x = EXPECT_CALL(foo, InitX());
Expectation init_y = EXPECT_CALL(foo, InitY());
EXPECT_CALL(foo, Bar())
.After(init_x, init_y);
```
says that `Bar()` can be called only after both `InitX()` and
`InitY()` have been called.
If you don't know how many pre-requisites an expectation has when you
write it, you can use an `ExpectationSet` to collect them:
```
using ::testing::ExpectationSet;
...
ExpectationSet all_inits;
for (int i = 0; i < element_count; i++) {
all_inits += EXPECT_CALL(foo, InitElement(i));
}
EXPECT_CALL(foo, Bar())
.After(all_inits);
```
says that `Bar()` can be called only after all elements have been
initialized (but we don't care about which elements get initialized
before the others).
Modifying an `ExpectationSet` after using it in an `.After()` doesn't
affect the meaning of the `.After()`.
## Sequences ##
When you have a long chain of sequential expectations, it's easier to
specify the order using **sequences**, which don't require you to given
each expectation in the chain a different name. <i>All expected<br>
calls</i> in the same sequence must occur in the order they are
specified.
```
using ::testing::Sequence;
Sequence s1, s2;
...
EXPECT_CALL(foo, Reset())
.InSequence(s1, s2)
.WillOnce(Return(true));
EXPECT_CALL(foo, GetSize())
.InSequence(s1)
.WillOnce(Return(1));
EXPECT_CALL(foo, Describe(A<const char*>()))
.InSequence(s2)
.WillOnce(Return("dummy"));
```
says that `Reset()` must be called before _both_ `GetSize()` _and_
`Describe()`, and the latter two can occur in any order.
To put many expectations in a sequence conveniently:
```
using ::testing::InSequence;
{
InSequence dummy;
EXPECT_CALL(...)...;
EXPECT_CALL(...)...;
...
EXPECT_CALL(...)...;
}
```
says that all expected calls in the scope of `dummy` must occur in
strict order. The name `dummy` is irrelevant.)
# Verifying and Resetting a Mock #
Google Mock will verify the expectations on a mock object when it is destructed, or you can do it earlier:
```
using ::testing::Mock;
...
// Verifies and removes the expectations on mock_obj;
// returns true iff successful.
Mock::VerifyAndClearExpectations(&mock_obj);
...
// Verifies and removes the expectations on mock_obj;
// also removes the default actions set by ON_CALL();
// returns true iff successful.
Mock::VerifyAndClear(&mock_obj);
```
You can also tell Google Mock that a mock object can be leaked and doesn't
need to be verified:
```
Mock::AllowLeak(&mock_obj);
```
# Mock Classes #
Google Mock defines a convenient mock class template
```
class MockFunction<R(A1, ..., An)> {
public:
MOCK_METHODn(Call, R(A1, ..., An));
};
```
See this [recipe](CookBook.md#using-check-points) for one application of it.
# Flags #
| `--gmock_catch_leaked_mocks=0` | Don't report leaked mock objects as failures. |
|:-------------------------------|:----------------------------------------------|
| `--gmock_verbose=LEVEL` | Sets the default verbosity level (`info`, `warning`, or `error`) of Google Mock messages. |

This page discusses the design of new Google Mock features.
# Macros for Defining Actions #
## Problem ##
Due to the lack of closures in C++, it currently requires some
non-trivial effort to define a custom action in Google Mock. For
example, suppose you want to "increment the value pointed to by the
second argument of the mock function and return it", you could write:
```
int IncrementArg1(Unused, int* p, Unused) {
return ++(*p);
}
... WillOnce(Invoke(IncrementArg1));
```
There are several things unsatisfactory about this approach:
* Even though the action only cares about the second argument of the mock function, its definition needs to list other arguments as dummies. This is tedious.
* The defined action is usable only in mock functions that takes exactly 3 arguments - an unnecessary restriction.
* To use the action, one has to say `Invoke(IncrementArg1)`, which isn't as nice as `IncrementArg1()`.
The latter two problems can be overcome using `MakePolymorphicAction()`,
but it requires much more boilerplate code:
```
class IncrementArg1Action {
public:
template <typename Result, typename ArgumentTuple>
Result Perform(const ArgumentTuple& args) const {
return ++(*tr1::get<1>(args));
}
};
PolymorphicAction<IncrementArg1Action> IncrementArg1() {
return MakePolymorphicAction(IncrementArg1Action());
}
... WillOnce(IncrementArg1());
```
Our goal is to allow defining custom actions with the least amount of
boiler-plate C++ requires.
## Solution ##
We propose to introduce a new macro:
```
ACTION(name) { statements; }
```
Using this in a namespace scope will define an action with the given
name that executes the statements. Inside the statements, you can
refer to the K-th (0-based) argument of the mock function as `argK`.
For example:
```
ACTION(IncrementArg1) { return ++(*arg1); }
```
allows you to write
```
... WillOnce(IncrementArg1());
```
Note that you don't need to specify the types of the mock function
arguments, as brevity is a top design goal here. Rest assured that
your code is still type-safe though: you'll get a compiler error if
`*arg1` doesn't support the `++` operator, or if the type of
`++(*arg1)` isn't compatible with the mock function's return type.
Another example:
```
ACTION(Foo) {
(*arg2)(5);
Blah();
*arg1 = 0;
return arg0;
}
```
defines an action `Foo()` that invokes argument #2 (a function pointer)
with 5, calls function `Blah()`, sets the value pointed to by argument
#1 to 0, and returns argument #0.
For more convenience and flexibility, you can also use the following
pre-defined symbols in the body of `ACTION`:
| `argK_type` | The type of the K-th (0-based) argument of the mock function |
|:------------|:-------------------------------------------------------------|
| `args` | All arguments of the mock function as a tuple |
| `args_type` | The type of all arguments of the mock function as a tuple |
| `return_type` | The return type of the mock function |
| `function_type` | The type of the mock function |
For example, when using an `ACTION` as a stub action for mock function:
```
int DoSomething(bool flag, int* ptr);
```
we have:
| **Pre-defined Symbol** | **Is Bound To** |
|:-----------------------|:----------------|
| `arg0` | the value of `flag` |
| `arg0_type` | the type `bool` |
| `arg1` | the value of `ptr` |
| `arg1_type` | the type `int*` |
| `args` | the tuple `(flag, ptr)` |
| `args_type` | the type `std::tr1::tuple<bool, int*>` |
| `return_type` | the type `int` |
| `function_type` | the type `int(bool, int*)` |
## Parameterized actions ##
Sometimes you'll want to parameterize the action. For that we propose
another macro
```
ACTION_P(name, param) { statements; }
```
For example,
```
ACTION_P(Add, n) { return arg0 + n; }
```
will allow you to write
```
// Returns argument #0 + 5.
... WillOnce(Add(5));
```
For convenience, we use the term _arguments_ for the values used to
invoke the mock function, and the term _parameters_ for the values
used to instantiate an action.
Note that you don't need to provide the type of the parameter either.
Suppose the parameter is named `param`, you can also use the
Google-Mock-defined symbol `param_type` to refer to the type of the
parameter as inferred by the compiler.
We will also provide `ACTION_P2`, `ACTION_P3`, and etc to support
multi-parameter actions. For example,
```
ACTION_P2(ReturnDistanceTo, x, y) {
double dx = arg0 - x;
double dy = arg1 - y;
return sqrt(dx*dx + dy*dy);
}
```
lets you write
```
... WillOnce(ReturnDistanceTo(5.0, 26.5));
```
You can view `ACTION` as a degenerated parameterized action where the
number of parameters is 0.
## Advanced Usages ##
### Overloading Actions ###
You can easily define actions overloaded on the number of parameters:
```
ACTION_P(Plus, a) { ... }
ACTION_P2(Plus, a, b) { ... }
```
### Restricting the Type of an Argument or Parameter ###
For maximum brevity and reusability, the `ACTION*` macros don't let
you specify the types of the mock function arguments and the action
parameters. Instead, we let the compiler infer the types for us.
Sometimes, however, we may want to be more explicit about the types.
There are several tricks to do that. For example:
```
ACTION(Foo) {
// Makes sure arg0 can be converted to int.
int n = arg0;
... use n instead of arg0 here ...
}
ACTION_P(Bar, param) {
// Makes sure the type of arg1 is const char*.
::testing::StaticAssertTypeEq<const char*, arg1_type>();
// Makes sure param can be converted to bool.
bool flag = param;
}
```
where `StaticAssertTypeEq` is a compile-time assertion we plan to add to
Google Test (the name is chosen to match `static_assert` in C++0x).
### Using the ACTION Object's Type ###
If you are writing a function that returns an `ACTION` object, you'll
need to know its type. The type depends on the macro used to define
the action and the parameter types. The rule is relatively simple:
| **Given Definition** | **Expression** | **Has Type** |
|:---------------------|:---------------|:-------------|
| `ACTION(Foo)` | `Foo()` | `FooAction` |
| `ACTION_P(Bar, param)` | `Bar(int_value)` | `BarActionP<int>` |
| `ACTION_P2(Baz, p1, p2)` | `Baz(bool_value, int_value)` | `BazActionP2<bool, int>` |
| ... | ... | ... |
Note that we have to pick different suffixes (`Action`, `ActionP`,
`ActionP2`, and etc) for actions with different numbers of parameters,
or the action definitions cannot be overloaded on the number of
parameters.
## When to Use ##
While the new macros are very convenient, please also consider other
means of implementing actions (e.g. via `ActionInterface` or
`MakePolymorphicAction()`), especially if you need to use the defined
action a lot. While the other approaches require more work, they give
you more control on the types of the mock function arguments and the
action parameters, which in general leads to better compiler error
messages that pay off in the long run. They also allow overloading
actions based on parameter types, as opposed to just the number of
parameters.
## Related Work ##
As you may have realized, the `ACTION*` macros resemble closures (also
known as lambda expressions or anonymous functions). Indeed, both of
them seek to lower the syntactic overhead for defining a function.
C++0x will support lambdas, but they are not part of C++ right now.
Some non-standard libraries (most notably BLL or Boost Lambda Library)
try to alleviate this problem. However, they are not a good choice
for defining actions as:
* They are non-standard and not widely installed. Google Mock only depends on standard libraries and `tr1::tuple`, which is part of the new C++ standard and comes with gcc 4+. We want to keep it that way.
* They are not trivial to learn.
* They will become obsolete when C++0x's lambda feature is widely supported. We don't want to make our users use a dying library.
* Since they are based on operators, they are rather ad hoc: you cannot use statements, and you cannot pass the lambda arguments to a function, for example.
* They have subtle semantics that easily confuses new users. For example, in expression `_1++ + foo++`, `foo` will be incremented only once where the expression is evaluated, while `_1` will be incremented every time the unnamed function is invoked. This is far from intuitive.
`ACTION*` avoid all these problems.
## Future Improvements ##
There may be a need for composing `ACTION*` definitions (i.e. invoking
another `ACTION` inside the definition of one `ACTION*`). We are not
sure we want it yet, as one can get a similar effect by putting
`ACTION` definitions in function templates and composing the function
templates. We'll revisit this based on user feedback.
The reason we don't allow `ACTION*()` inside a function body is that
the current C++ standard doesn't allow function-local types to be used
to instantiate templates. The upcoming C++0x standard will lift this
restriction. Once this feature is widely supported by compilers, we
can revisit the implementation and add support for using `ACTION*()`
inside a function.
C++0x will also support lambda expressions. When they become
available, we may want to support using lambdas as actions.
# Macros for Defining Matchers #
Once the macros for defining actions are implemented, we plan to do
the same for matchers:
```
MATCHER(name) { statements; }
```
where you can refer to the value being matched as `arg`. For example,
given:
```
MATCHER(IsPositive) { return arg > 0; }
```
you can use `IsPositive()` as a matcher that matches a value iff it is
greater than 0.
We will also add `MATCHER_P`, `MATCHER_P2`, and etc for parameterized
matchers.

First, let's give you some background of the project.
## Licensing ##
All Google Mock source and pre-built packages are provided under the [New BSD License](http://www.opensource.org/licenses/bsd-license.php).
## The Google Mock Community ##
The Google Mock community exists primarily through the [discussion group](http://groups.google.com/group/googlemock), the
[issue tracker](https://github.com/google/googletest/issues) and, to a lesser extent, the [source control repository](../). You are definitely encouraged to contribute to the
discussion and you can also help us to keep the effectiveness of the
group high by following and promoting the guidelines listed here.
### Please Be Friendly ###
Showing courtesy and respect to others is a vital part of the Google
culture, and we strongly encourage everyone participating in Google
Mock development to join us in accepting nothing less. Of course,
being courteous is not the same as failing to constructively disagree
with each other, but it does mean that we should be respectful of each
other when enumerating the 42 technical reasons that a particular
proposal may not be the best choice. There's never a reason to be
antagonistic or dismissive toward anyone who is sincerely trying to
contribute to a discussion.
Sure, C++ testing is serious business and all that, but it's also
a lot of fun. Let's keep it that way. Let's strive to be one of the
friendliest communities in all of open source.
### Where to Discuss Google Mock ###
As always, discuss Google Mock in the official [Google C++ Mocking Framework discussion group](http://groups.google.com/group/googlemock). You don't have to actually submit
code in order to sign up. Your participation itself is a valuable
contribution.
# Working with the Code #
If you want to get your hands dirty with the code inside Google Mock,
this is the section for you.
## Checking Out the Source from Subversion ##
Checking out the Google Mock source is most useful if you plan to
tweak it yourself. You check out the source for Google Mock using a
[Subversion](http://subversion.tigris.org/) client as you would for any
other project hosted on Google Code. Please see the instruction on
the [source code access page](../) for how to do it.
## Compiling from Source ##
Once you check out the code, you can find instructions on how to
compile it in the [README](../README.md) file.
## Testing ##
A mocking framework is of no good if itself is not thoroughly tested.
Tests should be written for any new code, and changes should be
verified to not break existing tests before they are submitted for
review. To perform the tests, follow the instructions in [README](http://code.google.com/p/googlemock/source/browse/trunk/README) and
verify that there are no failures.
# Contributing Code #
We are excited that Google Mock is now open source, and hope to get
great patches from the community. Before you fire up your favorite IDE
and begin hammering away at that new feature, though, please take the
time to read this section and understand the process. While it seems
rigorous, we want to keep a high standard of quality in the code
base.
## Contributor License Agreements ##
You must sign a Contributor License Agreement (CLA) before we can
accept any code. The CLA protects you and us.
* If you are an individual writing original source code and you're sure you own the intellectual property, then you'll need to sign an [individual CLA](http://code.google.com/legal/individual-cla-v1.0.html).
* If you work for a company that wants to allow you to contribute your work to Google Mock, then you'll need to sign a [corporate CLA](http://code.google.com/legal/corporate-cla-v1.0.html).
Follow either of the two links above to access the appropriate CLA and
instructions for how to sign and return it.
## Coding Style ##
To keep the source consistent, readable, diffable and easy to merge,
we use a fairly rigid coding style, as defined by the [google-styleguide](https://github.com/google/styleguide) project. All patches will be expected
to conform to the style outlined [here](https://google.github.io/styleguide/cppguide.html).
## Submitting Patches ##
Please do submit code. Here's what you need to do:
1. Normally you should make your change against the SVN trunk instead of a branch or a tag, as the latter two are for release control and should be treated mostly as read-only.
1. Decide which code you want to submit. A submission should be a set of changes that addresses one issue in the [Google Mock issue tracker](http://code.google.com/p/googlemock/issues/list). Please don't mix more than one logical change per submittal, because it makes the history hard to follow. If you want to make a change that doesn't have a corresponding issue in the issue tracker, please create one.
1. Also, coordinate with team members that are listed on the issue in question. This ensures that work isn't being duplicated and communicating your plan early also generally leads to better patches.
1. Ensure that your code adheres to the [Google Mock source code style](#Coding_Style.md).
1. Ensure that there are unit tests for your code.
1. Sign a Contributor License Agreement.
1. Create a patch file using `svn diff`.
1. We use [Rietveld](http://codereview.appspot.com/) to do web-based code reviews. You can read about the tool [here](https://github.com/rietveld-codereview/rietveld/wiki). When you are ready, upload your patch via Rietveld and notify `googlemock@googlegroups.com` to review it. There are several ways to upload the patch. We recommend using the [upload\_gmock.py](../scripts/upload_gmock.py) script, which you can find in the `scripts/` folder in the SVN trunk.
## Google Mock Committers ##
The current members of the Google Mock engineering team are the only
committers at present. In the great tradition of eating one's own
dogfood, we will be requiring each new Google Mock engineering team
member to earn the right to become a committer by following the
procedures in this document, writing consistently great code, and
demonstrating repeatedly that he or she truly gets the zen of Google
Mock.
# Release Process #
We follow the typical release process for Subversion-based projects:
1. A release branch named `release-X.Y` is created.
1. Bugs are fixed and features are added in trunk; those individual patches are merged into the release branch until it's stable.
1. An individual point release (the `Z` in `X.Y.Z`) is made by creating a tag from the branch.
1. Repeat steps 2 and 3 throughout one release cycle (as determined by features or time).
1. Go back to step 1 to create another release branch and so on.

# What Is Google C++ Mocking Framework? #
When you write a prototype or test, often it's not feasible or wise to rely on real objects entirely. A **mock object** implements the same interface as a real object (so it can be used as one), but lets you specify at run time how it will be used and what it should do (which methods will be called? in which order? how many times? with what arguments? what will they return? etc).
**Note:** It is easy to confuse the term _fake objects_ with mock objects. Fakes and mocks actually mean very different things in the Test-Driven Development (TDD) community:
* **Fake** objects have working implementations, but usually take some shortcut (perhaps to make the operations less expensive), which makes them not suitable for production. An in-memory file system would be an example of a fake.
* **Mocks** are objects pre-programmed with _expectations_, which form a specification of the calls they are expected to receive.
If all this seems too abstract for you, don't worry - the most important thing to remember is that a mock allows you to check the _interaction_ between itself and code that uses it. The difference between fakes and mocks will become much clearer once you start to use mocks.
**Google C++ Mocking Framework** (or **Google Mock** for short) is a library (sometimes we also call it a "framework" to make it sound cool) for creating mock classes and using them. It does to C++ what [jMock](http://www.jmock.org/) and [EasyMock](http://www.easymock.org/) do to Java.
Using Google Mock involves three basic steps:
1. Use some simple macros to describe the interface you want to mock, and they will expand to the implementation of your mock class;
1. Create some mock objects and specify its expectations and behavior using an intuitive syntax;
1. Exercise code that uses the mock objects. Google Mock will catch any violation of the expectations as soon as it arises.
# Why Google Mock? #
While mock objects help you remove unnecessary dependencies in tests and make them fast and reliable, using mocks manually in C++ is _hard_:
* Someone has to implement the mocks. The job is usually tedious and error-prone. No wonder people go great distances to avoid it.
* The quality of those manually written mocks is a bit, uh, unpredictable. You may see some really polished ones, but you may also see some that were hacked up in a hurry and have all sorts of ad-hoc restrictions.
* The knowledge you gained from using one mock doesn't transfer to the next.
In contrast, Java and Python programmers have some fine mock frameworks, which automate the creation of mocks. As a result, mocking is a proven effective technique and widely adopted practice in those communities. Having the right tool absolutely makes the difference.
Google Mock was built to help C++ programmers. It was inspired by [jMock](http://www.jmock.org/) and [EasyMock](http://www.easymock.org/), but designed with C++'s specifics in mind. It is your friend if any of the following problems is bothering you:
* You are stuck with a sub-optimal design and wish you had done more prototyping before it was too late, but prototyping in C++ is by no means "rapid".
* Your tests are slow as they depend on too many libraries or use expensive resources (e.g. a database).
* Your tests are brittle as some resources they use are unreliable (e.g. the network).
* You want to test how your code handles a failure (e.g. a file checksum error), but it's not easy to cause one.
* You need to make sure that your module interacts with other modules in the right way, but it's hard to observe the interaction; therefore you resort to observing the side effects at the end of the action, which is awkward at best.
* You want to "mock out" your dependencies, except that they don't have mock implementations yet; and, frankly, you aren't thrilled by some of those hand-written mocks.
We encourage you to use Google Mock as:
* a _design_ tool, for it lets you experiment with your interface design early and often. More iterations lead to better designs!
* a _testing_ tool to cut your tests' outbound dependencies and probe the interaction between your module and its collaborators.
# Getting Started #
Using Google Mock is easy! Inside your C++ source file, just `#include` `"gtest/gtest.h"` and `"gmock/gmock.h"`, and you are ready to go.
# A Case for Mock Turtles #
Let's look at an example. Suppose you are developing a graphics program that relies on a LOGO-like API for drawing. How would you test that it does the right thing? Well, you can run it and compare the screen with a golden screen snapshot, but let's admit it: tests like this are expensive to run and fragile (What if you just upgraded to a shiny new graphics card that has better anti-aliasing? Suddenly you have to update all your golden images.). It would be too painful if all your tests are like this. Fortunately, you learned about Dependency Injection and know the right thing to do: instead of having your application talk to the drawing API directly, wrap the API in an interface (say, `Turtle`) and code to that interface:
```
class Turtle {
...
virtual ~Turtle() {}
virtual void PenUp() = 0;
virtual void PenDown() = 0;
virtual void Forward(int distance) = 0;
virtual void Turn(int degrees) = 0;
virtual void GoTo(int x, int y) = 0;
virtual int GetX() const = 0;
virtual int GetY() const = 0;
};
```
(Note that the destructor of `Turtle` **must** be virtual, as is the case for **all** classes you intend to inherit from - otherwise the destructor of the derived class will not be called when you delete an object through a base pointer, and you'll get corrupted program states like memory leaks.)
You can control whether the turtle's movement will leave a trace using `PenUp()` and `PenDown()`, and control its movement using `Forward()`, `Turn()`, and `GoTo()`. Finally, `GetX()` and `GetY()` tell you the current position of the turtle.
Your program will normally use a real implementation of this interface. In tests, you can use a mock implementation instead. This allows you to easily check what drawing primitives your program is calling, with what arguments, and in which order. Tests written this way are much more robust (they won't break because your new machine does anti-aliasing differently), easier to read and maintain (the intent of a test is expressed in the code, not in some binary images), and run _much, much faster_.
# Writing the Mock Class #
If you are lucky, the mocks you need to use have already been implemented by some nice people. If, however, you find yourself in the position to write a mock class, relax - Google Mock turns this task into a fun game! (Well, almost.)
## How to Define It ##
Using the `Turtle` interface as example, here are the simple steps you need to follow:
1. Derive a class `MockTurtle` from `Turtle`.
1. Take a _virtual_ function of `Turtle` (while it's possible to [mock non-virtual methods using templates](CookBook.md#mocking-nonvirtual-methods), it's much more involved). Count how many arguments it has.
1. In the `public:` section of the child class, write `MOCK_METHODn();` (or `MOCK_CONST_METHODn();` if you are mocking a `const` method), where `n` is the number of the arguments; if you counted wrong, shame on you, and a compiler error will tell you so.
1. Now comes the fun part: you take the function signature, cut-and-paste the _function name_ as the _first_ argument to the macro, and leave what's left as the _second_ argument (in case you're curious, this is the _type of the function_).
1. Repeat until all virtual functions you want to mock are done.
After the process, you should have something like:
```
#include "gmock/gmock.h" // Brings in Google Mock.
class MockTurtle : public Turtle {
public:
...
MOCK_METHOD0(PenUp, void());
MOCK_METHOD0(PenDown, void());
MOCK_METHOD1(Forward, void(int distance));
MOCK_METHOD1(Turn, void(int degrees));
MOCK_METHOD2(GoTo, void(int x, int y));
MOCK_CONST_METHOD0(GetX, int());
MOCK_CONST_METHOD0(GetY, int());
};
```
You don't need to define these mock methods somewhere else - the `MOCK_METHOD*` macros will generate the definitions for you. It's that simple! Once you get the hang of it, you can pump out mock classes faster than your source-control system can handle your check-ins.
**Tip:** If even this is too much work for you, you'll find the
`gmock_gen.py` tool in Google Mock's `scripts/generator/` directory (courtesy of the [cppclean](http://code.google.com/p/cppclean/) project) useful. This command-line
tool requires that you have Python 2.4 installed. You give it a C++ file and the name of an abstract class defined in it,
and it will print the definition of the mock class for you. Due to the
complexity of the C++ language, this script may not always work, but
it can be quite handy when it does. For more details, read the [user documentation](../scripts/generator/README).
## Where to Put It ##
When you define a mock class, you need to decide where to put its definition. Some people put it in a `*_test.cc`. This is fine when the interface being mocked (say, `Foo`) is owned by the same person or team. Otherwise, when the owner of `Foo` changes it, your test could break. (You can't really expect `Foo`'s maintainer to fix every test that uses `Foo`, can you?)
So, the rule of thumb is: if you need to mock `Foo` and it's owned by others, define the mock class in `Foo`'s package (better, in a `testing` sub-package such that you can clearly separate production code and testing utilities), and put it in a `mock_foo.h`. Then everyone can reference `mock_foo.h` from their tests. If `Foo` ever changes, there is only one copy of `MockFoo` to change, and only tests that depend on the changed methods need to be fixed.
Another way to do it: you can introduce a thin layer `FooAdaptor` on top of `Foo` and code to this new interface. Since you own `FooAdaptor`, you can absorb changes in `Foo` much more easily. While this is more work initially, carefully choosing the adaptor interface can make your code easier to write and more readable (a net win in the long run), as you can choose `FooAdaptor` to fit your specific domain much better than `Foo` does.
# Using Mocks in Tests #
Once you have a mock class, using it is easy. The typical work flow is:
1. Import the Google Mock names from the `testing` namespace such that you can use them unqualified (You only have to do it once per file. Remember that namespaces are a good idea and good for your health.).
1. Create some mock objects.
1. Specify your expectations on them (How many times will a method be called? With what arguments? What should it do? etc.).
1. Exercise some code that uses the mocks; optionally, check the result using Google Test assertions. If a mock method is called more than expected or with wrong arguments, you'll get an error immediately.
1. When a mock is destructed, Google Mock will automatically check whether all expectations on it have been satisfied.
Here's an example:
```
#include "path/to/mock-turtle.h"
#include "gmock/gmock.h"
#include "gtest/gtest.h"
using ::testing::AtLeast; // #1
TEST(PainterTest, CanDrawSomething) {
MockTurtle turtle; // #2
EXPECT_CALL(turtle, PenDown()) // #3
.Times(AtLeast(1));
Painter painter(&turtle); // #4
EXPECT_TRUE(painter.DrawCircle(0, 0, 10));
} // #5
int main(int argc, char** argv) {
// The following line must be executed to initialize Google Mock
// (and Google Test) before running the tests.
::testing::InitGoogleMock(&argc, argv);
return RUN_ALL_TESTS();
}
```
As you might have guessed, this test checks that `PenDown()` is called at least once. If the `painter` object didn't call this method, your test will fail with a message like this:
```
path/to/my_test.cc:119: Failure
Actual function call count doesn't match this expectation:
Actually: never called;
Expected: called at least once.
```
**Tip 1:** If you run the test from an Emacs buffer, you can hit `<Enter>` on the line number displayed in the error message to jump right to the failed expectation.
**Tip 2:** If your mock objects are never deleted, the final verification won't happen. Therefore it's a good idea to use a heap leak checker in your tests when you allocate mocks on the heap.
**Important note:** Google Mock requires expectations to be set **before** the mock functions are called, otherwise the behavior is **undefined**. In particular, you mustn't interleave `EXPECT_CALL()`s and calls to the mock functions.
This means `EXPECT_CALL()` should be read as expecting that a call will occur _in the future_, not that a call has occurred. Why does Google Mock work like that? Well, specifying the expectation beforehand allows Google Mock to report a violation as soon as it arises, when the context (stack trace, etc) is still available. This makes debugging much easier.
Admittedly, this test is contrived and doesn't do much. You can easily achieve the same effect without using Google Mock. However, as we shall reveal soon, Google Mock allows you to do _much more_ with the mocks.
## Using Google Mock with Any Testing Framework ##
If you want to use something other than Google Test (e.g. [CppUnit](http://sourceforge.net/projects/cppunit/) or
[CxxTest](http://cxxtest.tigris.org/)) as your testing framework, just change the `main()` function in the previous section to:
```
int main(int argc, char** argv) {
// The following line causes Google Mock to throw an exception on failure,
// which will be interpreted by your testing framework as a test failure.
::testing::GTEST_FLAG(throw_on_failure) = true;
::testing::InitGoogleMock(&argc, argv);
... whatever your testing framework requires ...
}
```
This approach has a catch: it makes Google Mock throw an exception
from a mock object's destructor sometimes. With some compilers, this
sometimes causes the test program to crash. You'll still be able to
notice that the test has failed, but it's not a graceful failure.
A better solution is to use Google Test's
[event listener API](../../googletest/docs/AdvancedGuide.md#extending-google-test-by-handling-test-events)
to report a test failure to your testing framework properly. You'll need to
implement the `OnTestPartResult()` method of the event listener interface, but it
should be straightforward.
If this turns out to be too much work, we suggest that you stick with
Google Test, which works with Google Mock seamlessly (in fact, it is
technically part of Google Mock.). If there is a reason that you
cannot use Google Test, please let us know.
# Setting Expectations #
The key to using a mock object successfully is to set the _right expectations_ on it. If you set the expectations too strict, your test will fail as the result of unrelated changes. If you set them too loose, bugs can slip through. You want to do it just right such that your test can catch exactly the kind of bugs you intend it to catch. Google Mock provides the necessary means for you to do it "just right."
## General Syntax ##
In Google Mock we use the `EXPECT_CALL()` macro to set an expectation on a mock method. The general syntax is:
```
EXPECT_CALL(mock_object, method(matchers))
.Times(cardinality)
.WillOnce(action)
.WillRepeatedly(action);
```
The macro has two arguments: first the mock object, and then the method and its arguments. Note that the two are separated by a comma (`,`), not a period (`.`). (Why using a comma? The answer is that it was necessary for technical reasons.)
The macro can be followed by some optional _clauses_ that provide more information about the expectation. We'll discuss how each clause works in the coming sections.
This syntax is designed to make an expectation read like English. For example, you can probably guess that
```
using ::testing::Return;...
EXPECT_CALL(turtle, GetX())
.Times(5)
.WillOnce(Return(100))
.WillOnce(Return(150))
.WillRepeatedly(Return(200));
```
says that the `turtle` object's `GetX()` method will be called five times, it will return 100 the first time, 150 the second time, and then 200 every time. Some people like to call this style of syntax a Domain-Specific Language (DSL).
**Note:** Why do we use a macro to do this? It serves two purposes: first it makes expectations easily identifiable (either by `grep` or by a human reader), and second it allows Google Mock to include the source file location of a failed expectation in messages, making debugging easier.
## Matchers: What Arguments Do We Expect? ##
When a mock function takes arguments, we must specify what arguments we are expecting; for example:
```
// Expects the turtle to move forward by 100 units.
EXPECT_CALL(turtle, Forward(100));
```
Sometimes you may not want to be too specific (Remember that talk about tests being too rigid? Over specification leads to brittle tests and obscures the intent of tests. Therefore we encourage you to specify only what's necessary - no more, no less.). If you care to check that `Forward()` will be called but aren't interested in its actual argument, write `_` as the argument, which means "anything goes":
```
using ::testing::_;
...
// Expects the turtle to move forward.
EXPECT_CALL(turtle, Forward(_));
```
`_` is an instance of what we call **matchers**. A matcher is like a predicate and can test whether an argument is what we'd expect. You can use a matcher inside `EXPECT_CALL()` wherever a function argument is expected.
A list of built-in matchers can be found in the [CheatSheet](CheatSheet.md). For example, here's the `Ge` (greater than or equal) matcher:
```
using ::testing::Ge;...
EXPECT_CALL(turtle, Forward(Ge(100)));
```
This checks that the turtle will be told to go forward by at least 100 units.
## Cardinalities: How Many Times Will It Be Called? ##
The first clause we can specify following an `EXPECT_CALL()` is `Times()`. We call its argument a **cardinality** as it tells _how many times_ the call should occur. It allows us to repeat an expectation many times without actually writing it as many times. More importantly, a cardinality can be "fuzzy", just like a matcher can be. This allows a user to express the intent of a test exactly.
An interesting special case is when we say `Times(0)`. You may have guessed - it means that the function shouldn't be called with the given arguments at all, and Google Mock will report a Google Test failure whenever the function is (wrongfully) called.
We've seen `AtLeast(n)` as an example of fuzzy cardinalities earlier. For the list of built-in cardinalities you can use, see the [CheatSheet](CheatSheet.md).
The `Times()` clause can be omitted. **If you omit `Times()`, Google Mock will infer the cardinality for you.** The rules are easy to remember:
* If **neither** `WillOnce()` **nor** `WillRepeatedly()` is in the `EXPECT_CALL()`, the inferred cardinality is `Times(1)`.
* If there are `n WillOnce()`'s but **no** `WillRepeatedly()`, where `n` >= 1, the cardinality is `Times(n)`.
* If there are `n WillOnce()`'s and **one** `WillRepeatedly()`, where `n` >= 0, the cardinality is `Times(AtLeast(n))`.
**Quick quiz:** what do you think will happen if a function is expected to be called twice but actually called four times?
## Actions: What Should It Do? ##
Remember that a mock object doesn't really have a working implementation? We as users have to tell it what to do when a method is invoked. This is easy in Google Mock.
First, if the return type of a mock function is a built-in type or a pointer, the function has a **default action** (a `void` function will just return, a `bool` function will return `false`, and other functions will return 0). In addition, in C++ 11 and above, a mock function whose return type is default-constructible (i.e. has a default constructor) has a default action of returning a default-constructed value. If you don't say anything, this behavior will be used.
Second, if a mock function doesn't have a default action, or the default action doesn't suit you, you can specify the action to be taken each time the expectation matches using a series of `WillOnce()` clauses followed by an optional `WillRepeatedly()`. For example,
```
using ::testing::Return;...
EXPECT_CALL(turtle, GetX())
.WillOnce(Return(100))
.WillOnce(Return(200))
.WillOnce(Return(300));
```
This says that `turtle.GetX()` will be called _exactly three times_ (Google Mock inferred this from how many `WillOnce()` clauses we've written, since we didn't explicitly write `Times()`), and will return 100, 200, and 300 respectively.
```
using ::testing::Return;...
EXPECT_CALL(turtle, GetY())
.WillOnce(Return(100))
.WillOnce(Return(200))
.WillRepeatedly(Return(300));
```
says that `turtle.GetY()` will be called _at least twice_ (Google Mock knows this as we've written two `WillOnce()` clauses and a `WillRepeatedly()` while having no explicit `Times()`), will return 100 the first time, 200 the second time, and 300 from the third time on.
Of course, if you explicitly write a `Times()`, Google Mock will not try to infer the cardinality itself. What if the number you specified is larger than there are `WillOnce()` clauses? Well, after all `WillOnce()`s are used up, Google Mock will do the _default_ action for the function every time (unless, of course, you have a `WillRepeatedly()`.).
What can we do inside `WillOnce()` besides `Return()`? You can return a reference using `ReturnRef(variable)`, or invoke a pre-defined function, among [others](CheatSheet.md#actions).
**Important note:** The `EXPECT_CALL()` statement evaluates the action clause only once, even though the action may be performed many times. Therefore you must be careful about side effects. The following may not do what you want:
```
int n = 100;
EXPECT_CALL(turtle, GetX())
.Times(4)
.WillRepeatedly(Return(n++));
```
Instead of returning 100, 101, 102, ..., consecutively, this mock function will always return 100 as `n++` is only evaluated once. Similarly, `Return(new Foo)` will create a new `Foo` object when the `EXPECT_CALL()` is executed, and will return the same pointer every time. If you want the side effect to happen every time, you need to define a custom action, which we'll teach in the [CookBook](CookBook.md).
Time for another quiz! What do you think the following means?
```
using ::testing::Return;...
EXPECT_CALL(turtle, GetY())
.Times(4)
.WillOnce(Return(100));
```
Obviously `turtle.GetY()` is expected to be called four times. But if you think it will return 100 every time, think twice! Remember that one `WillOnce()` clause will be consumed each time the function is invoked and the default action will be taken afterwards. So the right answer is that `turtle.GetY()` will return 100 the first time, but **return 0 from the second time on**, as returning 0 is the default action for `int` functions.
## Using Multiple Expectations ##
So far we've only shown examples where you have a single expectation. More realistically, you're going to specify expectations on multiple mock methods, which may be from multiple mock objects.
By default, when a mock method is invoked, Google Mock will search the expectations in the **reverse order** they are defined, and stop when an active expectation that matches the arguments is found (you can think of it as "newer rules override older ones."). If the matching expectation cannot take any more calls, you will get an upper-bound-violated failure. Here's an example:
```
using ::testing::_;...
EXPECT_CALL(turtle, Forward(_)); // #1
EXPECT_CALL(turtle, Forward(10)) // #2
.Times(2);
```
If `Forward(10)` is called three times in a row, the third time it will be an error, as the last matching expectation (#2) has been saturated. If, however, the third `Forward(10)` call is replaced by `Forward(20)`, then it would be OK, as now #1 will be the matching expectation.
**Side note:** Why does Google Mock search for a match in the _reverse_ order of the expectations? The reason is that this allows a user to set up the default expectations in a mock object's constructor or the test fixture's set-up phase and then customize the mock by writing more specific expectations in the test body. So, if you have two expectations on the same method, you want to put the one with more specific matchers **after** the other, or the more specific rule would be shadowed by the more general one that comes after it.
## Ordered vs Unordered Calls ##
By default, an expectation can match a call even though an earlier expectation hasn't been satisfied. In other words, the calls don't have to occur in the order the expectations are specified.
Sometimes, you may want all the expected calls to occur in a strict order. To say this in Google Mock is easy:
```
using ::testing::InSequence;...
TEST(FooTest, DrawsLineSegment) {
...
{
InSequence dummy;
EXPECT_CALL(turtle, PenDown());
EXPECT_CALL(turtle, Forward(100));
EXPECT_CALL(turtle, PenUp());
}
Foo();
}
```
By creating an object of type `InSequence`, all expectations in its scope are put into a _sequence_ and have to occur _sequentially_. Since we are just relying on the constructor and destructor of this object to do the actual work, its name is really irrelevant.
In this example, we test that `Foo()` calls the three expected functions in the order as written. If a call is made out-of-order, it will be an error.
(What if you care about the relative order of some of the calls, but not all of them? Can you specify an arbitrary partial order? The answer is ... yes! If you are impatient, the details can be found in the [CookBook](CookBook.md#expecting-partially-ordered-calls).)
## All Expectations Are Sticky (Unless Said Otherwise) ##
Now let's do a quick quiz to see how well you can use this mock stuff already. How would you test that the turtle is asked to go to the origin _exactly twice_ (you want to ignore any other instructions it receives)?
After you've come up with your answer, take a look at ours and compare notes (solve it yourself first - don't cheat!):
```
using ::testing::_;...
EXPECT_CALL(turtle, GoTo(_, _)) // #1
.Times(AnyNumber());
EXPECT_CALL(turtle, GoTo(0, 0)) // #2
.Times(2);
```
Suppose `turtle.GoTo(0, 0)` is called three times. In the third time, Google Mock will see that the arguments match expectation #2 (remember that we always pick the last matching expectation). Now, since we said that there should be only two such calls, Google Mock will report an error immediately. This is basically what we've told you in the "Using Multiple Expectations" section above.
This example shows that **expectations in Google Mock are "sticky" by default**, in the sense that they remain active even after we have reached their invocation upper bounds. This is an important rule to remember, as it affects the meaning of the spec, and is **different** to how it's done in many other mocking frameworks (Why'd we do that? Because we think our rule makes the common cases easier to express and understand.).
Simple? Let's see if you've really understood it: what does the following code say?
```
using ::testing::Return;
...
for (int i = n; i > 0; i--) {
EXPECT_CALL(turtle, GetX())
.WillOnce(Return(10*i));
}
```
If you think it says that `turtle.GetX()` will be called `n` times and will return 10, 20, 30, ..., consecutively, think twice! The problem is that, as we said, expectations are sticky. So, the second time `turtle.GetX()` is called, the last (latest) `EXPECT_CALL()` statement will match, and will immediately lead to an "upper bound exceeded" error - this piece of code is not very useful!
One correct way of saying that `turtle.GetX()` will return 10, 20, 30, ..., is to explicitly say that the expectations are _not_ sticky. In other words, they should _retire_ as soon as they are saturated:
```
using ::testing::Return;
...
for (int i = n; i > 0; i--) {
EXPECT_CALL(turtle, GetX())
.WillOnce(Return(10*i))
.RetiresOnSaturation();
}
```
And, there's a better way to do it: in this case, we expect the calls to occur in a specific order, and we line up the actions to match the order. Since the order is important here, we should make it explicit using a sequence:
```
using ::testing::InSequence;
using ::testing::Return;
...
{
InSequence s;
for (int i = 1; i <= n; i++) {
EXPECT_CALL(turtle, GetX())
.WillOnce(Return(10*i))
.RetiresOnSaturation();
}
}
```
By the way, the other situation where an expectation may _not_ be sticky is when it's in a sequence - as soon as another expectation that comes after it in the sequence has been used, it automatically retires (and will never be used to match any call).
## Uninteresting Calls ##
A mock object may have many methods, and not all of them are that interesting. For example, in some tests we may not care about how many times `GetX()` and `GetY()` get called.
In Google Mock, if you are not interested in a method, just don't say anything about it. If a call to this method occurs, you'll see a warning in the test output, but it won't be a failure.

Please send your questions to the

## When I call a method on my mock object, the method for the real object is invoked instead. What's the problem? ##
In order for a method to be mocked, it must be _virtual_, unless you use the [high-perf dependency injection technique](CookBook.md#mocking-nonvirtual-methods).
## I wrote some matchers. After I upgraded to a new version of Google Mock, they no longer compile. What's going on? ##
After version 1.4.0 of Google Mock was released, we had an idea on how
to make it easier to write matchers that can generate informative
messages efficiently. We experimented with this idea and liked what
we saw. Therefore we decided to implement it.
Unfortunately, this means that if you have defined your own matchers
by implementing `MatcherInterface` or using `MakePolymorphicMatcher()`,
your definitions will no longer compile. Matchers defined using the
`MATCHER*` family of macros are not affected.
Sorry for the hassle if your matchers are affected. We believe it's
in everyone's long-term interest to make this change sooner than
later. Fortunately, it's usually not hard to migrate an existing
matcher to the new API. Here's what you need to do:
If you wrote your matcher like this:
```
// Old matcher definition that doesn't work with the latest
// Google Mock.
using ::testing::MatcherInterface;
...
class MyWonderfulMatcher : public MatcherInterface<MyType> {
public:
...
virtual bool Matches(MyType value) const {
// Returns true if value matches.
return value.GetFoo() > 5;
}
...
};
```
you'll need to change it to:
```
// New matcher definition that works with the latest Google Mock.
using ::testing::MatcherInterface;
using ::testing::MatchResultListener;
...
class MyWonderfulMatcher : public MatcherInterface<MyType> {
public:
...
virtual bool MatchAndExplain(MyType value,
MatchResultListener* listener) const {
// Returns true if value matches.
return value.GetFoo() > 5;
}
...
};
```
(i.e. rename `Matches()` to `MatchAndExplain()` and give it a second
argument of type `MatchResultListener*`.)
If you were also using `ExplainMatchResultTo()` to improve the matcher
message:
```
// Old matcher definition that doesn't work with the lastest
// Google Mock.
using ::testing::MatcherInterface;
...
class MyWonderfulMatcher : public MatcherInterface<MyType> {
public:
...
virtual bool Matches(MyType value) const {
// Returns true if value matches.
return value.GetFoo() > 5;
}
virtual void ExplainMatchResultTo(MyType value,
::std::ostream* os) const {
// Prints some helpful information to os to help
// a user understand why value matches (or doesn't match).
*os << "the Foo property is " << value.GetFoo();
}
...
};
```
you should move the logic of `ExplainMatchResultTo()` into
`MatchAndExplain()`, using the `MatchResultListener` argument where
the `::std::ostream` was used:
```
// New matcher definition that works with the latest Google Mock.
using ::testing::MatcherInterface;
using ::testing::MatchResultListener;
...
class MyWonderfulMatcher : public MatcherInterface<MyType> {
public:
...
virtual bool MatchAndExplain(MyType value,
MatchResultListener* listener) const {
// Returns true if value matches.
*listener << "the Foo property is " << value.GetFoo();
return value.GetFoo() > 5;
}
...
};
```
If your matcher is defined using `MakePolymorphicMatcher()`:
```
// Old matcher definition that doesn't work with the latest
// Google Mock.
using ::testing::MakePolymorphicMatcher;
...
class MyGreatMatcher {
public:
...
bool Matches(MyType value) const {
// Returns true if value matches.
return value.GetBar() < 42;
}
...
};
... MakePolymorphicMatcher(MyGreatMatcher()) ...
```
you should rename the `Matches()` method to `MatchAndExplain()` and
add a `MatchResultListener*` argument (the same as what you need to do
for matchers defined by implementing `MatcherInterface`):
```
// New matcher definition that works with the latest Google Mock.
using ::testing::MakePolymorphicMatcher;
using ::testing::MatchResultListener;
...
class MyGreatMatcher {
public:
...
bool MatchAndExplain(MyType value,
MatchResultListener* listener) const {
// Returns true if value matches.
return value.GetBar() < 42;
}
...
};
... MakePolymorphicMatcher(MyGreatMatcher()) ...
```
If your polymorphic matcher uses `ExplainMatchResultTo()` for better
failure messages:
```
// Old matcher definition that doesn't work with the latest
// Google Mock.
using ::testing::MakePolymorphicMatcher;
...
class MyGreatMatcher {
public:
...
bool Matches(MyType value) const {
// Returns true if value matches.
return value.GetBar() < 42;
}
...
};
void ExplainMatchResultTo(const MyGreatMatcher& matcher,
MyType value,
::std::ostream* os) {
// Prints some helpful information to os to help
// a user understand why value matches (or doesn't match).
*os << "the Bar property is " << value.GetBar();
}
... MakePolymorphicMatcher(MyGreatMatcher()) ...
```
you'll need to move the logic inside `ExplainMatchResultTo()` to
`MatchAndExplain()`:
```
// New matcher definition that works with the latest Google Mock.
using ::testing::MakePolymorphicMatcher;
using ::testing::MatchResultListener;
...
class MyGreatMatcher {
public:
...
bool MatchAndExplain(MyType value,
MatchResultListener* listener) const {
// Returns true if value matches.
*listener << "the Bar property is " << value.GetBar();
return value.GetBar() < 42;
}
...
};
... MakePolymorphicMatcher(MyGreatMatcher()) ...
```

are welcome to post questions on `googlemock@googlegroups.com` if you
need any help.
## When using Google Mock, do I have to use Google Test as the testing framework? I have my favorite testing framework and don't want to switch. ##
Google Mock works out of the box with Google Test. However, it's easy
to configure it to work with any testing framework of your choice.
[Here](ForDummies.md#using-google-mock-with-any-testing-framework) is how.
## How am I supposed to make sense of these horrible template errors? ##
If you are confused by the compiler errors gcc threw at you,
try consulting the _Google Mock Doctor_ tool first. What it does is to
scan stdin for gcc error messages, and spit out diagnoses on the
problems (we call them diseases) your code has.
To "install", run command:
```
alias gmd='<path to googlemock>/scripts/gmock_doctor.py'
```
To use it, do:
```
<your-favorite-build-command> <your-test> 2>&1 | gmd
```
For example:
```
make my_test 2>&1 | gmd
```
Or you can run `gmd` and copy-n-paste gcc's error messages to it.
## Can I mock a variadic function? ##
You cannot mock a variadic function (i.e. a function taking ellipsis
(`...`) arguments) directly in Google Mock.
The problem is that in general, there is _no way_ for a mock object to
know how many arguments are passed to the variadic method, and what
the arguments' types are. Only the _author of the base class_ knows
the protocol, and we cannot look into his head.
Therefore, to mock such a function, the _user_ must teach the mock
object how to figure out the number of arguments and their types. One
way to do it is to provide overloaded versions of the function.
Ellipsis arguments are inherited from C and not really a C++ feature.
They are unsafe to use and don't work with arguments that have
constructors or destructors. Therefore we recommend to avoid them in
C++ as much as possible.
## MSVC gives me warning C4301 or C4373 when I define a mock method with a const parameter. Why? ##
If you compile this using Microsoft Visual C++ 2005 SP1:
```
class Foo {
...
virtual void Bar(const int i) = 0;
};
class MockFoo : public Foo {
...
MOCK_METHOD1(Bar, void(const int i));
};
```
You may get the following warning:
```
warning C4301: 'MockFoo::Bar': overriding virtual function only differs from 'Foo::Bar' by const/volatile qualifier
```
This is a MSVC bug. The same code compiles fine with gcc ,for
example. If you use Visual C++ 2008 SP1, you would get the warning:
```
warning C4373: 'MockFoo::Bar': virtual function overrides 'Foo::Bar', previous versions of the compiler did not override when parameters only differed by const/volatile qualifiers
```
In C++, if you _declare_ a function with a `const` parameter, the
`const` modifier is _ignored_. Therefore, the `Foo` base class above
is equivalent to:
```
class Foo {
...
virtual void Bar(int i) = 0; // int or const int? Makes no difference.
};
```
In fact, you can _declare_ Bar() with an `int` parameter, and _define_
it with a `const int` parameter. The compiler will still match them
up.
Since making a parameter `const` is meaningless in the method
_declaration_, we recommend to remove it in both `Foo` and `MockFoo`.
That should workaround the VC bug.
Note that we are talking about the _top-level_ `const` modifier here.
If the function parameter is passed by pointer or reference, declaring
the _pointee_ or _referee_ as `const` is still meaningful. For
example, the following two declarations are _not_ equivalent:
```
void Bar(int* p); // Neither p nor *p is const.
void Bar(const int* p); // p is not const, but *p is.
```
## I have a huge mock class, and Microsoft Visual C++ runs out of memory when compiling it. What can I do? ##
We've noticed that when the `/clr` compiler flag is used, Visual C++
uses 5~6 times as much memory when compiling a mock class. We suggest
to avoid `/clr` when compiling native C++ mocks.
## I can't figure out why Google Mock thinks my expectations are not satisfied. What should I do? ##
You might want to run your test with
`--gmock_verbose=info`. This flag lets Google Mock print a trace
of every mock function call it receives. By studying the trace,
you'll gain insights on why the expectations you set are not met.
## How can I assert that a function is NEVER called? ##
```
EXPECT_CALL(foo, Bar(_))
.Times(0);
```
## I have a failed test where Google Mock tells me TWICE that a particular expectation is not satisfied. Isn't this redundant? ##
When Google Mock detects a failure, it prints relevant information
(the mock function arguments, the state of relevant expectations, and
etc) to help the user debug. If another failure is detected, Google
Mock will do the same, including printing the state of relevant
expectations.
Sometimes an expectation's state didn't change between two failures,
and you'll see the same description of the state twice. They are
however _not_ redundant, as they refer to _different points in time_.
The fact they are the same _is_ interesting information.
## I get a heap check failure when using a mock object, but using a real object is fine. What can be wrong? ##
Does the class (hopefully a pure interface) you are mocking have a
virtual destructor?
Whenever you derive from a base class, make sure its destructor is
virtual. Otherwise Bad Things will happen. Consider the following
code:
```
class Base {
public:
// Not virtual, but should be.
~Base() { ... }
...
};
class Derived : public Base {
public:
...
private:
std::string value_;
};
...
Base* p = new Derived;
...
delete p; // Surprise! ~Base() will be called, but ~Derived() will not
// - value_ is leaked.
```
By changing `~Base()` to virtual, `~Derived()` will be correctly
called when `delete p` is executed, and the heap checker
will be happy.
## The "newer expectations override older ones" rule makes writing expectations awkward. Why does Google Mock do that? ##
When people complain about this, often they are referring to code like:
```
// foo.Bar() should be called twice, return 1 the first time, and return
// 2 the second time. However, I have to write the expectations in the
// reverse order. This sucks big time!!!
EXPECT_CALL(foo, Bar())
.WillOnce(Return(2))
.RetiresOnSaturation();
EXPECT_CALL(foo, Bar())
.WillOnce(Return(1))
.RetiresOnSaturation();
```
The problem is that they didn't pick the **best** way to express the test's
intent.
By default, expectations don't have to be matched in _any_ particular
order. If you want them to match in a certain order, you need to be
explicit. This is Google Mock's (and jMock's) fundamental philosophy: it's
easy to accidentally over-specify your tests, and we want to make it
harder to do so.
There are two better ways to write the test spec. You could either
put the expectations in sequence:
```
// foo.Bar() should be called twice, return 1 the first time, and return
// 2 the second time. Using a sequence, we can write the expectations
// in their natural order.
{
InSequence s;
EXPECT_CALL(foo, Bar())
.WillOnce(Return(1))
.RetiresOnSaturation();
EXPECT_CALL(foo, Bar())
.WillOnce(Return(2))
.RetiresOnSaturation();
}
```
or you can put the sequence of actions in the same expectation:
```
// foo.Bar() should be called twice, return 1 the first time, and return
// 2 the second time.
EXPECT_CALL(foo, Bar())
.WillOnce(Return(1))
.WillOnce(Return(2))
.RetiresOnSaturation();
```
Back to the original questions: why does Google Mock search the
expectations (and `ON_CALL`s) from back to front? Because this
allows a user to set up a mock's behavior for the common case early
(e.g. in the mock's constructor or the test fixture's set-up phase)
and customize it with more specific rules later. If Google Mock
searches from front to back, this very useful pattern won't be
possible.
## Google Mock prints a warning when a function without EXPECT\_CALL is called, even if I have set its behavior using ON\_CALL. Would it be reasonable not to show the warning in this case? ##
When choosing between being neat and being safe, we lean toward the
latter. So the answer is that we think it's better to show the
warning.
Often people write `ON_CALL`s in the mock object's
constructor or `SetUp()`, as the default behavior rarely changes from
test to test. Then in the test body they set the expectations, which
are often different for each test. Having an `ON_CALL` in the set-up
part of a test doesn't mean that the calls are expected. If there's
no `EXPECT_CALL` and the method is called, it's possibly an error. If
we quietly let the call go through without notifying the user, bugs
may creep in unnoticed.
If, however, you are sure that the calls are OK, you can write
```
EXPECT_CALL(foo, Bar(_))
.WillRepeatedly(...);
```
instead of
```
ON_CALL(foo, Bar(_))
.WillByDefault(...);
```
This tells Google Mock that you do expect the calls and no warning should be
printed.
Also, you can control the verbosity using the `--gmock_verbose` flag.
If you find the output too noisy when debugging, just choose a less
verbose level.
## How can I delete the mock function's argument in an action? ##
If you find yourself needing to perform some action that's not
supported by Google Mock directly, remember that you can define your own
actions using
[MakeAction()](CookBook.md#writing-new-actions) or
[MakePolymorphicAction()](CookBook.md#writing_new_polymorphic_actions),
or you can write a stub function and invoke it using
[Invoke()](CookBook.md#using-functions_methods_functors).
## MOCK\_METHODn()'s second argument looks funny. Why don't you use the MOCK\_METHODn(Method, return\_type, arg\_1, ..., arg\_n) syntax? ##
What?! I think it's beautiful. :-)
While which syntax looks more natural is a subjective matter to some
extent, Google Mock's syntax was chosen for several practical advantages it
has.
Try to mock a function that takes a map as an argument:
```
virtual int GetSize(const map<int, std::string>& m);
```
Using the proposed syntax, it would be:
```
MOCK_METHOD1(GetSize, int, const map<int, std::string>& m);
```
Guess what? You'll get a compiler error as the compiler thinks that
`const map<int, std::string>& m` are **two**, not one, arguments. To work
around this you can use `typedef` to give the map type a name, but
that gets in the way of your work. Google Mock's syntax avoids this
problem as the function's argument types are protected inside a pair
of parentheses:
```
// This compiles fine.
MOCK_METHOD1(GetSize, int(const map<int, std::string>& m));
```
You still need a `typedef` if the return type contains an unprotected
comma, but that's much rarer.
Other advantages include:
1. `MOCK_METHOD1(Foo, int, bool)` can leave a reader wonder whether the method returns `int` or `bool`, while there won't be such confusion using Google Mock's syntax.
1. The way Google Mock describes a function type is nothing new, although many people may not be familiar with it. The same syntax was used in C, and the `function` library in `tr1` uses this syntax extensively. Since `tr1` will become a part of the new version of STL, we feel very comfortable to be consistent with it.
1. The function type syntax is also used in other parts of Google Mock's API (e.g. the action interface) in order to make the implementation tractable. A user needs to learn it anyway in order to utilize Google Mock's more advanced features. We'd as well stick to the same syntax in `MOCK_METHOD*`!
## My code calls a static/global function. Can I mock it? ##
You can, but you need to make some changes.
In general, if you find yourself needing to mock a static function,
it's a sign that your modules are too tightly coupled (and less
flexible, less reusable, less testable, etc). You are probably better
off defining a small interface and call the function through that
interface, which then can be easily mocked. It's a bit of work
initially, but usually pays for itself quickly.
This Google Testing Blog
[post](http://googletesting.blogspot.com/2008/06/defeat-static-cling.html)
says it excellently. Check it out.
## My mock object needs to do complex stuff. It's a lot of pain to specify the actions. Google Mock sucks! ##
I know it's not a question, but you get an answer for free any way. :-)
With Google Mock, you can create mocks in C++ easily. And people might be
tempted to use them everywhere. Sometimes they work great, and
sometimes you may find them, well, a pain to use. So, what's wrong in
the latter case?
When you write a test without using mocks, you exercise the code and
assert that it returns the correct value or that the system is in an
expected state. This is sometimes called "state-based testing".
Mocks are great for what some call "interaction-based" testing:
instead of checking the system state at the very end, mock objects
verify that they are invoked the right way and report an error as soon
as it arises, giving you a handle on the precise context in which the
error was triggered. This is often more effective and economical to
do than state-based testing.
If you are doing state-based testing and using a test double just to
simulate the real object, you are probably better off using a fake.
Using a mock in this case causes pain, as it's not a strong point for
mocks to perform complex actions. If you experience this and think
that mocks suck, you are just not using the right tool for your
problem. Or, you might be trying to solve the wrong problem. :-)
## I got a warning "Uninteresting function call encountered - default action taken.." Should I panic? ##
By all means, NO! It's just an FYI.
What it means is that you have a mock function, you haven't set any
expectations on it (by Google Mock's rule this means that you are not
interested in calls to this function and therefore it can be called
any number of times), and it is called. That's OK - you didn't say
it's not OK to call the function!
What if you actually meant to disallow this function to be called, but
forgot to write `EXPECT_CALL(foo, Bar()).Times(0)`? While
one can argue that it's the user's fault, Google Mock tries to be nice and
prints you a note.
So, when you see the message and believe that there shouldn't be any
uninteresting calls, you should investigate what's going on. To make
your life easier, Google Mock prints the function name and arguments
when an uninteresting call is encountered.
## I want to define a custom action. Should I use Invoke() or implement the action interface? ##
Either way is fine - you want to choose the one that's more convenient
for your circumstance.
Usually, if your action is for a particular function type, defining it
using `Invoke()` should be easier; if your action can be used in
functions of different types (e.g. if you are defining
`Return(value)`), `MakePolymorphicAction()` is
easiest. Sometimes you want precise control on what types of
functions the action can be used in, and implementing
`ActionInterface` is the way to go here. See the implementation of
`Return()` in `include/gmock/gmock-actions.h` for an example.
## I'm using the set-argument-pointee action, and the compiler complains about "conflicting return type specified". What does it mean? ##
You got this error as Google Mock has no idea what value it should return
when the mock method is called. `SetArgPointee()` says what the
side effect is, but doesn't say what the return value should be. You
need `DoAll()` to chain a `SetArgPointee()` with a `Return()`.
See this [recipe](CookBook.md#mocking_side_effects) for more details and an example.
## My question is not in your FAQ! ##
If you cannot find the answer to your question in this FAQ, there are
some other resources you can use:
1. read other [documentation](Documentation.md),
1. search the mailing list [archive](http://groups.google.com/group/googlemock/topics),
1. ask it on [googlemock@googlegroups.com](mailto:googlemock@googlegroups.com) and someone will answer it (to prevent spam, we require you to join the [discussion group](http://groups.google.com/group/googlemock) before you can post.).
Please note that creating an issue in the
[issue tracker](https://github.com/google/googletest/issues) is _not_
a good way to get your answer, as it is monitored infrequently by a
very small number of people.
When asking a question, it's helpful to provide as much of the
following information as possible (people cannot help you if there's
not enough information in your question):
* the version (or the revision number if you check out from SVN directly) of Google Mock you use (Google Mock is under active development, so it's possible that your problem has been solved in a later version),
* your operating system,
* the name and version of your compiler,
* the complete command line flags you give to your compiler,
* the complete compiler error messages (if the question is about compilation),
* the _actual_ code (ideally, a minimal but complete program) that has the problem you encounter.

As any non-trivial software system, Google Mock has some known limitations and problems. We are working on improving it, and welcome your help! The follow is a list of issues we know about.
## README contains outdated information on Google Mock's compatibility with other testing frameworks ##
The `README` file in release 1.1.0 still says that Google Mock only works with Google Test. Actually, you can configure Google Mock to work with any testing framework you choose.
## Tests failing on machines using Power PC CPUs (e.g. some Macs) ##
`gmock_output_test` and `gmock-printers_test` are known to fail with Power PC CPUs. This is due to portability issues with these tests, and is not an indication of problems in Google Mock itself. You can safely ignore them.
## Failed to resolve libgtest.so.0 in tests when built against installed Google Test ##
This only applies if you manually built and installed Google Test, and then built a Google Mock against it (either explicitly, or because gtest-config was in your path post-install). In this situation, Libtool has a known issue with certain systems' ldconfig setup:
http://article.gmane.org/gmane.comp.sysutils.automake.general/9025
This requires a manual run of "sudo ldconfig" after the "sudo make install" for Google Test before any binaries which link against it can be executed. This isn't a bug in our install, but we should at least have documented it or hacked a work-around into our install. We should have one of these solutions in our next release.

// The ACTION* family of macros can be used in a namespace scope to
// define custom actions easily. The syntax:
//
// ACTION(name) { statements; }
//
// will define an action with the given name that executes the
// statements. The value returned by the statements will be used as
// the return value of the action. Inside the statements, you can
// refer to the K-th (0-based) argument of the mock function by
// 'argK', and refer to its type by 'argK_type'. For example:
//
// ACTION(IncrementArg1) {
// arg1_type temp = arg1;
// return ++(*temp);
// }
//
// allows you to write
//
// ...WillOnce(IncrementArg1());
//
// You can also refer to the entire argument tuple and its type by
// 'args' and 'args_type', and refer to the mock function type and its
// return type by 'function_type' and 'return_type'.
//
// Note that you don't need to specify the types of the mock function
// arguments. However rest assured that your code is still type-safe:
// you'll get a compiler error if *arg1 doesn't support the ++
// operator, or if the type of ++(*arg1) isn't compatible with the
// mock function's return type, for example.
//
// Sometimes you'll want to parameterize the action. For that you can use
// another macro:
//
// ACTION_P(name, param_name) { statements; }
//
// For example:
//
// ACTION_P(Add, n) { return arg0 + n; }
//
// will allow you to write:
//
// ...WillOnce(Add(5));
//
// Note that you don't need to provide the type of the parameter
// either. If you need to reference the type of a parameter named
// 'foo', you can write 'foo_type'. For example, in the body of
// ACTION_P(Add, n) above, you can write 'n_type' to refer to the type
// of 'n'.
//
// We also provide ACTION_P2, ACTION_P3, ..., up to ACTION_P$n to support
// multi-parameter actions.
//
// For the purpose of typing, you can view
//
// ACTION_Pk(Foo, p1, ..., pk) { ... }
//
// as shorthand for
//
// template <typename p1_type, ..., typename pk_type>
// FooActionPk<p1_type, ..., pk_type> Foo(p1_type p1, ..., pk_type pk) { ... }
//
// In particular, you can provide the template type arguments
// explicitly when invoking Foo(), as in Foo<long, bool>(5, false);
// although usually you can rely on the compiler to infer the types
// for you automatically. You can assign the result of expression
// Foo(p1, ..., pk) to a variable of type FooActionPk<p1_type, ...,
// pk_type>. This can be useful when composing actions.
//
// You can also overload actions with different numbers of parameters:
//
// ACTION_P(Plus, a) { ... }
// ACTION_P2(Plus, a, b) { ... }
//
// While it's tempting to always use the ACTION* macros when defining
// a new action, you should also consider implementing ActionInterface
// or using MakePolymorphicAction() instead, especially if you need to
// use the action a lot. While these approaches require more work,
// they give you more control on the types of the mock function
// arguments and the action parameters, which in general leads to
// better compiler error messages that pay off in the long run. They
// also allow overloading actions based on parameter types (as opposed
// to just based on the number of parameters).
//
// CAVEAT:
//
// ACTION*() can only be used in a namespace scope. The reason is
// that C++ doesn't yet allow function-local types to be used to
// instantiate templates. The up-coming C++0x standard will fix this.
// Once that's done, we'll consider supporting using ACTION*() inside
// a function.
//

//

// Sometimes you want to give an action explicit template parameters
// that cannot be inferred from its value parameters. ACTION() and
// ACTION_P*() don't support that. ACTION_TEMPLATE() remedies that
// and can be viewed as an extension to ACTION() and ACTION_P*().
//
// The syntax:
//
// ACTION_TEMPLATE(ActionName,
// HAS_m_TEMPLATE_PARAMS(kind1, name1, ..., kind_m, name_m),
// AND_n_VALUE_PARAMS(p1, ..., p_n)) { statements; }
//
// defines an action template that takes m explicit template
// parameters and n value parameters. name_i is the name of the i-th
// template parameter, and kind_i specifies whether it's a typename,
// an integral constant, or a template. p_i is the name of the i-th
// value parameter.
//
// Example:
//
// // DuplicateArg<k, T>(output) converts the k-th argument of the mock
// // function to type T and copies it to *output.
// ACTION_TEMPLATE(DuplicateArg,
// HAS_2_TEMPLATE_PARAMS(int, k, typename, T),
// AND_1_VALUE_PARAMS(output)) {
// *output = T(::testing::get<k>(args));
// }
// ...
// int n;
// EXPECT_CALL(mock, Foo(_, _))
// .WillOnce(DuplicateArg<1, unsigned char>(&n));
//
// To create an instance of an action template, write:
//
// ActionName<t1, ..., t_m>(v1, ..., v_n)
//
// where the ts are the template arguments and the vs are the value
// arguments. The value argument types are inferred by the compiler.
// If you want to explicitly specify the value argument types, you can
// provide additional template arguments:
//
// ActionName<t1, ..., t_m, u1, ..., u_k>(v1, ..., v_n)
//
// where u_i is the desired type of v_i.
//
// ACTION_TEMPLATE and ACTION/ACTION_P* can be overloaded on the
// number of value parameters, but not on the number of template
// parameters. Without the restriction, the meaning of the following
// is unclear:
//
// OverloadedAction<int, bool>(x);
//
// Are we using a single-template-parameter action where 'bool' refers
// to the type of x, or are we using a two-template-parameter action
// where the compiler is asked to infer the type of x?
//
// Implementation notes:
//
// GMOCK_INTERNAL_*_HAS_m_TEMPLATE_PARAMS and
// GMOCK_INTERNAL_*_AND_n_VALUE_PARAMS are internal macros for
// implementing ACTION_TEMPLATE. The main trick we use is to create
// new macro invocations when expanding a macro. For example, we have
//
// #define ACTION_TEMPLATE(name, template_params, value_params)
// ... GMOCK_INTERNAL_DECL_##template_params ...
//
// which causes ACTION_TEMPLATE(..., HAS_1_TEMPLATE_PARAMS(typename, T), ...)
// to expand to
//
// ... GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS(typename, T) ...
//
// Since GMOCK_INTERNAL_DECL_HAS_1_TEMPLATE_PARAMS is a macro, the
// preprocessor will continue to expand it to
//
// ... typename T ...
//
// This technique conforms to the C++ standard and is portable. It
// allows us to implement action templates using O(N) code, where N is
// the maximum number of template/value parameters supported. Without
// using it, we'd have to devote O(N^2) amount of code to implement all
// combinations of m and n.

// A MockFunction<F> class has one mock method whose type is F. It is
// useful when you just want your test code to emit some messages and
// have Google Mock verify the right messages are sent (and perhaps at
// the right times). For example, if you are exercising code:
//
// Foo(1);
// Foo(2);
// Foo(3);
//
// and want to verify that Foo(1) and Foo(3) both invoke
// mock.Bar("a"), but Foo(2) doesn't invoke anything, you can write:
//
// TEST(FooTest, InvokesBarCorrectly) {
// MyMock mock;
// MockFunction<void(string check_point_name)> check;
// {
// InSequence s;
//
// EXPECT_CALL(mock, Bar("a"));
// EXPECT_CALL(check, Call("1"));
// EXPECT_CALL(check, Call("2"));
// EXPECT_CALL(mock, Bar("a"));
// }
// Foo(1);
// check.Call("1");
// Foo(2);
// check.Call("2");
// Foo(3);
// }
//
// The expectation spec says that the first Bar("a") must happen
// before check point "1", the second Bar("a") must happen after check
// point "2", and nothing should happen between the two check
// points. The explicit check points make it easy to tell which
// Bar("a") is called by which call to Foo().
//
// MockFunction<F> can also be used to exercise code that accepts
// std::function<F> callbacks. To do so, use AsStdFunction() method
// to create std::function proxy forwarding to original object's Call.
// Example:
//
// TEST(FooTest, RunsCallbackWithBarArgument) {
// MockFunction<int(string)> callback;
// EXPECT_CALL(callback, Call("bar")).WillOnce(Return(1));
// Foo(callback.AsStdFunction());

$$ // show up in the generated code.
// The MATCHER* family of macros can be used in a namespace scope to
// define custom matchers easily.
//
// Basic Usage
// ===========
//
// The syntax
//
// MATCHER(name, description_string) { statements; }
//
// defines a matcher with the given name that executes the statements,
// which must return a bool to indicate if the match succeeds. Inside
// the statements, you can refer to the value being matched by 'arg',
// and refer to its type by 'arg_type'.
//
// The description string documents what the matcher does, and is used
// to generate the failure message when the match fails. Since a
// MATCHER() is usually defined in a header file shared by multiple
// C++ source files, we require the description to be a C-string
// literal to avoid possible side effects. It can be empty, in which
// case we'll use the sequence of words in the matcher name as the
// description.
//
// For example:
//
// MATCHER(IsEven, "") { return (arg % 2) == 0; }
//
// allows you to write
//
// // Expects mock_foo.Bar(n) to be called where n is even.
// EXPECT_CALL(mock_foo, Bar(IsEven()));
//
// or,
//
// // Verifies that the value of some_expression is even.
// EXPECT_THAT(some_expression, IsEven());
//
// If the above assertion fails, it will print something like:
//
// Value of: some_expression
// Expected: is even
// Actual: 7
//
// where the description "is even" is automatically calculated from the
// matcher name IsEven.
//
// Argument Type
// =============
//
// Note that the type of the value being matched (arg_type) is
// determined by the context in which you use the matcher and is
// supplied to you by the compiler, so you don't need to worry about
// declaring it (nor can you). This allows the matcher to be
// polymorphic. For example, IsEven() can be used to match any type
// where the value of "(arg % 2) == 0" can be implicitly converted to
// a bool. In the "Bar(IsEven())" example above, if method Bar()
// takes an int, 'arg_type' will be int; if it takes an unsigned long,
// 'arg_type' will be unsigned long; and so on.
//
// Parameterizing Matchers
// =======================
//
// Sometimes you'll want to parameterize the matcher. For that you
// can use another macro:
//
// MATCHER_P(name, param_name, description_string) { statements; }
//
// For example:
//
// MATCHER_P(HasAbsoluteValue, value, "") { return abs(arg) == value; }
//
// will allow you to write:
//
// EXPECT_THAT(Blah("a"), HasAbsoluteValue(n));
//
// which may lead to this message (assuming n is 10):
//
// Value of: Blah("a")
// Expected: has absolute value 10
// Actual: -9
//
// Note that both the matcher description and its parameter are
// printed, making the message human-friendly.
//
// In the matcher definition body, you can write 'foo_type' to
// reference the type of a parameter named 'foo'. For example, in the
// body of MATCHER_P(HasAbsoluteValue, value) above, you can write
// 'value_type' to refer to the type of 'value'.
//
// We also provide MATCHER_P2, MATCHER_P3, ..., up to MATCHER_P$n to
// support multi-parameter matchers.
//
// Describing Parameterized Matchers
// =================================
//
// The last argument to MATCHER*() is a string-typed expression. The
// expression can reference all of the matcher's parameters and a
// special bool-typed variable named 'negation'. When 'negation' is
// false, the expression should evaluate to the matcher's description;
// otherwise it should evaluate to the description of the negation of
// the matcher. For example,
//
// using testing::PrintToString;
//
// MATCHER_P2(InClosedRange, low, hi,
// string(negation ? "is not" : "is") + " in range [" +
// PrintToString(low) + ", " + PrintToString(hi) + "]") {
// return low <= arg && arg <= hi;
// }
// ...
// EXPECT_THAT(3, InClosedRange(4, 6));
// EXPECT_THAT(3, Not(InClosedRange(2, 4)));
//
// would generate two failures that contain the text:
//
// Expected: is in range [4, 6]
// ...
// Expected: is not in range [2, 4]
//
// If you specify "" as the description, the failure message will
// contain the sequence of words in the matcher name followed by the
// parameter values printed as a tuple. For example,
//
// MATCHER_P2(InClosedRange, low, hi, "") { ... }
// ...
// EXPECT_THAT(3, InClosedRange(4, 6));
// EXPECT_THAT(3, Not(InClosedRange(2, 4)));
//
// would generate two failures that contain the text:
//
// Expected: in closed range (4, 6)
// ...
// Expected: not (in closed range (2, 4))
//
// Types of Matcher Parameters
// ===========================
//
// For the purpose of typing, you can view
//
// MATCHER_Pk(Foo, p1, ..., pk, description_string) { ... }
//
// as shorthand for
//
// template <typename p1_type, ..., typename pk_type>
// FooMatcherPk<p1_type, ..., pk_type>
// Foo(p1_type p1, ..., pk_type pk) { ... }
//
// When you write Foo(v1, ..., vk), the compiler infers the types of
// the parameters v1, ..., and vk for you. If you are not happy with
// the result of the type inference, you can specify the types by
// explicitly instantiating the template, as in Foo<long, bool>(5,
// false). As said earlier, you don't get to (or need to) specify
// 'arg_type' as that's determined by the context in which the matcher
// is used. You can assign the result of expression Foo(p1, ..., pk)
// to a variable of type FooMatcherPk<p1_type, ..., pk_type>. This
// can be useful when composing matchers.
//
// While you can instantiate a matcher template with reference types,
// passing the parameters by pointer usually makes your code more
// readable. If, however, you still want to pass a parameter by
// reference, be aware that in the failure message generated by the
// matcher you will see the value of the referenced object but not its
// address.
//
// Explaining Match Results
// ========================
//
// Sometimes the matcher description alone isn't enough to explain why
// the match has failed or succeeded. For example, when expecting a
// long string, it can be very helpful to also print the diff between
// the expected string and the actual one. To achieve that, you can
// optionally stream additional information to a special variable
// named result_listener, whose type is a pointer to class
// MatchResultListener:
//
// MATCHER_P(EqualsLongString, str, "") {
// if (arg == str) return true;
//
// *result_listener << "the difference: "
/// << DiffStrings(str, arg);
// return false;
// }
//
// Overloading Matchers
// ====================
//
// You can overload matchers with different numbers of parameters:
//
// MATCHER_P(Blah, a, description_string1) { ... }
// MATCHER_P2(Blah, a, b, description_string2) { ... }
//
// Caveats
// =======
//
// When defining a new matcher, you should also consider implementing
// MatcherInterface or using MakePolymorphicMatcher(). These
// approaches require more work than the MATCHER* macros, but also
// give you more control on the types of the value being matched and
// the matcher parameters, which may leads to better compiler error
// messages when the matcher is used wrong. They also allow
// overloading matchers based on parameter types (as opposed to just
// based on the number of parameters).
//
// MATCHER*() can only be used in a namespace scope. The reason is
// that C++ doesn't yet allow function-local types to be used to
// instantiate templates. The up-coming C++0x standard will fix this.
// Once that's done, we'll consider supporting using MATCHER*() inside
// a function.
//
// More Information
// ================
//
// To learn more about using these macros, please search for 'MATCHER'
// on http://code.google.com/p/googlemock/wiki/CookBook.

// Implements class templates NiceMock, NaggyMock, and StrictMock.
//
// Given a mock class MockFoo that is created using Google Mock,
// NiceMock<MockFoo> is a subclass of MockFoo that allows
// uninteresting calls (i.e. calls to mock methods that have no
// EXPECT_CALL specs), NaggyMock<MockFoo> is a subclass of MockFoo
// that prints a warning when an uninteresting call occurs, and
// StrictMock<MockFoo> is a subclass of MockFoo that treats all
// uninteresting calls as errors.
//
// Currently a mock is naggy by default, so MockFoo and
// NaggyMock<MockFoo> behave like the same. However, we will soon
// switch the default behavior of mocks to be nice, as that in general
// leads to more maintainable tests. When that happens, MockFoo will
// stop behaving like NaggyMock<MockFoo> and start behaving like
// NiceMock<MockFoo>.
//
// NiceMock, NaggyMock, and StrictMock "inherit" the constructors of
// their respective base class, with up-to 10 arguments. Therefore
// you can write NiceMock<MockFoo>(5, "a") to construct a nice mock
// where MockFoo has a constructor that accepts (int, const char*),
// for example.
//
// A known limitation is that NiceMock<MockFoo>, NaggyMock<MockFoo>,
// and StrictMock<MockFoo> only works for mock methods defined using
// the MOCK_METHOD* family of macros DIRECTLY in the MockFoo class.
// If a mock method is defined in a base class of MockFoo, the "nice"
// or "strict" modifier may not affect it, depending on the compiler.
// In particular, nesting NiceMock, NaggyMock, and StrictMock is NOT
// supported.
//
// Another known limitation is that the constructors of the base mock
// cannot have arguments passed by non-const reference, which are
// banned by the Google C++ style guide anyway.

// Implements class templates NiceMock, NaggyMock, and StrictMock.
//
// Given a mock class MockFoo that is created using Google Mock,
// NiceMock<MockFoo> is a subclass of MockFoo that allows
// uninteresting calls (i.e. calls to mock methods that have no
// EXPECT_CALL specs), NaggyMock<MockFoo> is a subclass of MockFoo
// that prints a warning when an uninteresting call occurs, and
// StrictMock<MockFoo> is a subclass of MockFoo that treats all
// uninteresting calls as errors.
//
// Currently a mock is naggy by default, so MockFoo and
// NaggyMock<MockFoo> behave like the same. However, we will soon
// switch the default behavior of mocks to be nice, as that in general
// leads to more maintainable tests. When that happens, MockFoo will
// stop behaving like NaggyMock<MockFoo> and start behaving like
// NiceMock<MockFoo>.
//
// NiceMock, NaggyMock, and StrictMock "inherit" the constructors of
// their respective base class, with up-to $n arguments. Therefore
// you can write NiceMock<MockFoo>(5, "a") to construct a nice mock
// where MockFoo has a constructor that accepts (int, const char*),
// for example.
//
// A known limitation is that NiceMock<MockFoo>, NaggyMock<MockFoo>,
// and StrictMock<MockFoo> only works for mock methods defined using
// the MOCK_METHOD* family of macros DIRECTLY in the MockFoo class.
// If a mock method is defined in a base class of MockFoo, the "nice"
// or "strict" modifier may not affect it, depending on the compiler.
// In particular, nesting NiceMock, NaggyMock, and StrictMock is NOT
// supported.
//
// Another known limitation is that the constructors of the base mock
// cannot have arguments passed by non-const reference, which are
// banned by the Google C++ style guide anyway.
