I'm curious what your take of the two mocks I've recently added to Lucene's codebase is - MockFilter and MockInputStream. Both of these are for sending in to somewhere else and probing what happens to them. How else could a Real Deal (tm) work in these scenarios? And, I would argue that these two are the real deals since they merely are implementations (although certainly minimal and exploratory) of the real interfaces of Lucene.I looked at both of these and I think that in this case neither of them seems an 'abuse' of mocking. If anything, this is the exact usage of what a mock should be, whiteboxing a blackbox scenario, where you can interact with it, then poke about and verify the results of that interaction.
I don't know if you're used dynamic mocks or the big fat library of mocks in the mockobjects-java project, but THAT stuff to me is a pretty blatant abuse. Full (useless) mocks of all of j2ee, where you're endlessly forced to define expectations and results for every call. Yuck!
