Experience from 2 days ago: I had CC write a bunch of tests to make sure some refactoring didn't break anything, and then I ran the app and it crashed out of the gate. Why? Because despite the verbosity of the tests it turns out that it had mocked the most import parts to test, so the _actual_ connections weren't being tested, and while CC was happy to claim victory with all tests green, the app was broken.
