FixtureTrait provides functionalities for loading, unloading and accessing fixtures for a test case.

By using FixtureTrait, a test class will be able to specify which fixtures to load by overriding the fixtures() method. It can then load and unload the fixtures using loadFixtures() and unloadFixtures(). Once a fixture is loaded, it can be accessed like an object property, thanks to the PHP __get() magic method. Also, if the fixture is an instance of yii\test\ActiveFixture, you will be able to access AR models through the syntax $this->fixtureName('model name').

For more details and usage information on FixtureTrait, see the guide article on fixtures.

Method Details

createFixtures() protected method

Creates the specified fixture instances.

All dependent fixtures will also be created.

protected yii\test\Fixture[] createFixtures ( array $fixtures )
$fixtures array

The fixtures to be created. You may provide fixture names or fixture configurations. If this parameter is not provided, the fixtures specified in globalFixtures() and fixtures() will be created.

return yii\test\Fixture[]

The created fixture instances

throws yii\base\InvalidConfigException

if fixtures are not properly configured or if a circular dependency among the fixtures is detected.

fixtures() public method

Declares the fixtures that are needed by the current test case.

The return value of this method must be an array of fixture configurations. For example,

[
    // anonymous fixture
    PostFixture::className(),
    // "users" fixture
    'users' => UserFixture::className(),
    // "cache" fixture with configuration
    'cache' => [
         'class' => CacheFixture::className(),
         'host' => 'xxx',
    ],
]

Note that the actual fixtures used for a test case will include both globalFixtures() and fixtures().

public array fixtures ( )
return array

The fixtures needed by the current test case

getFixture() public method

Returns the named fixture.

public yii\test\Fixture getFixture ( $name )
$name string

The fixture name. This can be either the fixture alias name, or the class name if the alias is not used.

return yii\test\Fixture

The fixture object, or null if the named fixture does not exist.

getFixtures() public method

Returns the fixture objects as specified in globalFixtures() and fixtures().

public yii\test\Fixture[] getFixtures ( )
return yii\test\Fixture[]

The loaded fixtures for the current test case

globalFixtures() public method

Declares the fixtures shared required by different test cases.

The return value should be similar to that of fixtures(). You should usually override this method in a base class.

See also fixtures().

public array globalFixtures ( )
return array

The fixtures shared and required by different test cases.

initFixtures() public method (available since version 2.0.12)

Initialize the fixtures

public void initFixtures ( )
loadFixtures() public method

Loads the specified fixtures.

This method will call yii\test\Fixture::load() for every fixture object.

public void loadFixtures ( $fixtures null )
$fixtures yii\test\Fixture[]

The fixtures to be loaded. If this parameter is not specified, the return value of getFixtures() will be used.

unloadFixtures() public method

Unloads the specified fixtures.

This method will call yii\test\Fixture::unload() for every fixture object.

public void unloadFixtures ( $fixtures null )
$fixtures yii\test\Fixture[]

The fixtures to be loaded. If this parameter is not specified, the return value of getFixtures() will be used.
