>However, I don't think it has to be like this. I sometimes call mocking "wish based design". Sometimes you don't really know what shape is going to be good.

That's why I write executable specs at a high level with my "wish based design", make that "test" pass and then refactor. Wish first -> code next -> only well designed code after that.

I don't feel the need to dive down another level and mock out real modules that are already covered by this high level test. That's just creating unnecessary work for myself and introducing a potential source of test bugs (where the mock doesn't match the reality).
