I find mocks useful for testing conditions that are on the periphery and would be a decent amount of trouble to set up. For instance, if I have a REST controller that has a catch all for exceptions that maps everything to a 500 response, I want a test that will cause the DAO layer to throw an exception and test that the rest of the "real stack" will do the translation correctly. A mock is the easiest way to accomplish that.
