Where can I see an example of testing a yii application?

Question

Yii

Good afternoon.
Tell me, where can I find the source code for yii, where would all the necessary tests be written? Both modular and functional. For example, a blog from a demo application and all covered with tests.
Otherwise, I can't figure out how to organize these tests. I read the theory. But here's an example that's sorely lacking. I watched examples of tests of the framework itself. But these are purely unit tests, but I want to see the whole picture.
Maybe someone writes an application and tests for it with open source. Or there is an example on github. Please share the link. I will be very grateful.

Answer 1

Keywords: Yii Codeception. Some documentation.

Answer 2

Go to github.com , search for keywords like Yii, Test, Testing and see the results.
