I agree about OOP and FP but this doesn't mean everything is like that. Classical style unit tests are much much better than London style unit tests.

@witchedwiz I didn't say you should never use mock. You should mock all calls to external systems. What you shouldn't do is to mock all calls outside the "class under test" because such unit tests are terrible.

@witchedwiz it is better to go top down without mocks except when mocking calls outside the system. You don't need to write unit tests for a class that is already covered by unit tests of its client classes.
