Summary

In this chapter, we came to appreciate the breadth and the quality of Codeception.

We've seen the three types of tests, namely unit, functional, and acceptance, which we'll be using throughout the rest of the book. We've also touched some additional features provided by the tool and by the Yii 2 Codeception module. We've learned how to interact with it, generate tests, and deal with debugging and keeping the test databases in sync with the database of the main application.

In the next chapter, we're going to start refactoring our User class, adding our tests first and progressing through all the most important PHPUnit features.
