// These flags can be in a @gate pragma to declare that a test depends on
|
||
// certain conditions. They're like GKs.
|
||
//
|
||
// Examples:
|
||
// // @gate enableBlocksAPI
|
||
// test('uses an unstable API', () => {/*...*/})
|
||
//
|
||
// // @gate isDev
|
||
// test('only passes in development', () => {/*...*/})
|
||
//
|
||
// Most flags are defined in ReactFeatureFlags. If it's defined there, you don't
|
||
// have to do anything extra here.
|
||
//
|
||
// There are also flags based on the environment, like isDev. Feel free to
|
||
// add new flags and aliases below.
|
||
//
|
||
// You can also combine flags using multiple gates:
|
||
//
|
||
// // @gate enableBlocksAPI
|
||
// // @gate isDev
|
||
// test('both conditions must pass', () => {/*...*/})
|
||
//
|
||
// Or using logical operators
|
||
// // @gate enableBlocksAPI && isDev
|
||
// test('both conditions must pass', () => {/*...*/})
|
||
//
|
||
// Negation also works:
|
||
// // @gate !deprecateLegacyContext
|
||
// test('uses a deprecated feature', () => {/*...*/})
|
||
|
||
// These flags are based on the environment and don't change for the entire
|
||
// test run.
