Using fixtures for acceptance testing

So I added this line of code:


inside the acceptance.suite.yml file of my codeception folder.

I generated the code and everything by entering codecept build inside my basic template folder; however, the problem is I don’t see the folder _support at all. How do I generate this folder? Also, do I only need the file FixtureHelper or are there other files that I would need along with it to do my acceptance testing? Also, how do I add entries to my test database for my acceptance tests? Sorry, there doesn’t seem to be any resources on how to do this on Yii2. I tried to run acceptance tests without FixtureHelper and it worked, but I would like to do the acceptance tests with some database entries.
