When you test a module, especially when you use TDD to drive the design of the code, you shouldn’t test classes or functions in isolation. Going “too low” with the unit tests (class by class, method by method) takes away almost all “Characteristics of good tests” (as described above). That’s because you don’t test the key element of the design, that is the interactions between classes/functions. Such a test suite exhibits an excessive usage of a mocking framework (and it’s a sign of a bad test suite; probably a large number of tests only check that method A invokes method B).
