This is the 17th video in the Getting Started with Rails 7 series. In this video Mike refactors the existing tests to move shared tests between models to a helper module that both test classes include. In addition, he creates a method to test that all fixtures are valid for each model. After that, he moves some of the repeated controller assertions into private methods.
