How can I inject interface into controller's constructor in Yii2

Question

I would like to inject interface app\models\IFoo

private $foo;

public function __construct($id, $module, IFoo $foo, array $config = [])
{
    parent::__construct($id, $module, $config);
    $this->foo = $foo;
}

How should I set container to correct resolving the dependency in concrete class app\models\Foo which implements IFoo?

Can you explain what is the purpose of this? Might be easier to answer. — Bizley

I've implemented IFoo in two concrete classes: Foo and FooStub. I would like to use stub for testing and so on. And I want inject interface into controller and set concrete class in setup file (web.php or other). — GraDea

Try to call it like that in entry script:

\Yii::$container->set('app\models\IFoo', $concreteClass);

where $concreteClass is either 'app\models\Foo' or 'app\models\FooStub'.

I guess you can add it in web.php for non-test env and in test.php for test env.
