 * ],
 * 'fixture' => [
 *     'class' => 'yii\test\DbFixtureManager',
 * ],
 * ~~~
 *
 * ~~~
 * #load fixtures under $fixturePath to the "users" table
 * yii fixture/apply users
 *
 * #also a short version of this command (generate action is default)

 *
 * #load fixtures under $fixturePath to the "users" table to the different connection
 * yii fixture/apply users --db=someOtherDbConneciton
