Custom Mailer for tests

Yii 2.0 Testing
1

I’m overriding Mailer class with my own and use it to create queue of emails.

When I run tests, it seems to be using another class (Codeception\Lib\Connector\Yii2\TestMailer), which I understood form this Exception:




[yii\base\UnknownMethodException] Calling unknown method: Codeception\Lib\Connector\Yii2\TestMailer:

And the questions is the following: how to set custom Mailing class for tests? Where do I need to set it up?

This is my own issue :)
