ActiveFixture represents a fixture backed up by a ActiveRecord class or a database table.
Either $modelClass or $tableName must be set. You should also provide fixture data in the file specified by $dataFile or overriding getData() if you want to use code to generate the fixture data.
When the fixture is being loaded, it will first call resetTable() to remove any existing data in the table. It will then populate the table with the data returned by getData().
After the fixture is loaded, you can access the loaded data via the $data property. If you set $modelClass, you will also be able to retrieve an instance of $modelClass with the populated data via getModel().
For more details and usage information on ActiveFixture, see the guide article on fixtures.

Property Details
The file path or path alias of the data file that contains the fixture data
to be returned by getData(). If this is not set, it will default to FixturePath/data/TableName.php,
where FixturePath stands for the directory containing this fixture class, and TableName stands for the
name of the table associated with this fixture. You can set this property to be false to prevent loading any data.
The name of the database table that this fixture is about. If this property is not set, the table name will be determined via $modelClass.
See also $modelClass.
The schema information of the database table associated with this fixture. This property is read-only.
Method Details
Returns the fixture data.
The default implementation will try to return the fixture data by including the external file specified by $dataFile. The file should return an array of data rows (column name => column value), each corresponding to a row in the table.
If the data file does not exist, an empty array will be returned.
| protected array getData ( ) | ||
| return | array | The data rows to be inserted into the database table. |
|---|---|---|
| public yii\db\TableSchema getTableSchema ( ) | ||
| return | yii\db\TableSchema | The schema information of the database table associated with this fixture. |
|---|---|---|
| throws | yii\base\InvalidConfigException | if the table does not exist |
Initializes the object.
This method is invoked at the end of the constructor after the object is initialized with the given configuration.
| public void init ( ) |
Loads the fixture.
It populate the table with the data returned by getData().
If you override this method, you should consider calling the parent implementation so that the data returned by getData() can be populated into the table.
| public void load ( ) |
Removes all existing data from the specified table and resets sequence number to 1 (if any).
This method is called before populating fixture data into the table associated with this fixture.
| protected void resetTable ( ) |
Unloads the fixture.
This method is called after every test method finishes. You may override this method to perform necessary cleanup work for the fixture.
| public void unload ( ) |
