<h3>Parameters specified as nested elements</h3>
|
|
<h4>exactly one supported condition</h4>
|
|
|
|
<p>You can use all supported conditions of Ant's core as well as
|
|
any class that implements the Condition interface as a nested
|
|
child element. This element is required - exactly one child - and
|
|
specifies the condition to assert.</p>
|
|
|
|
<h3>Examples</h3>
|
|
|
|
<p>Make the build fail with the message "foo is bar" if the
|
|
property foo has the value bar:</p>
|
|
|
|
<pre>
|
|
<assertTrue message="foo is bar">
|
|
<not>
|
|
<equals arg1="${foo}" arg2="bar"/>
|
|
</not>
|
|
</assertTrue message="foo is bar">
|
|
</pre>
