PHPUnit + Selenuim [ + Yii ] - how to specify the size of the maximize window (maximized)?

Question

Yii

Getting to know PHPUnit by testing a Yii application. When I ran an acceptance test using Codeception, I could specify in the config the size or status of the browser window in which the test would be conducted. For example, you could expand it to see what's there and how. Here, in PHPStorm+PHPUnit+Selenium+Yii, I can't find/google the right option.
Is there a solution to this problem?

Answer 1

found solution for Yii1
$this->windowMaximize();
