How to test your Yii2 extension?

Question

Yii

I'm writing a module extension for Yii2. Created a project in PhpStorm, with the following structure
root
| -components/
| -models/
| - services/
| - tests/
| -Module.php
| - codecept.phar
| - composer.json
i.e. I did not drag all the framework code behind the project, but connected it via include_path in the PhpStorm settings
. I called the php codecept.phar bootstrap command, a folder with tests was created. How can I run the tests now (I wrote several tests for writing / reading from the database using Command \ Query)? Is it really necessary to pull all yii dependencies through "composer install"?
