Trait yii\test\FixtureTrait

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.

| fixtures() | Declares the fixtures that are needed by the current test case. | yii\test\FixtureTrait |
| getFixture() | Returns the named fixture. | yii\test\FixtureTrait |
| getFixtures() | Returns the fixture objects as specified in globalFixtures() and fixtures(). | yii\test\FixtureTrait |
| globalFixtures() | Declares the fixtures shared required by different test cases. | yii\test\FixtureTrait |
| initFixtures() | Initialize the fixtures. | yii\test\FixtureTrait |
| loadFixtures() | Loads the specified fixtures. | yii\test\FixtureTrait |

Protected Methods
| Method | Description | Defined By |
|---|---|---|
| createFixtures() | Creates the specified fixture instances. | yii\test\FixtureTrait |
Method Details
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. |
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 |
|---|---|---|
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. |
|---|---|---|
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 |
|---|---|---|
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. |
|---|---|---|
Initialize the fixtures.
| public void initFixtures ( ) |
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. |
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. |
