You raise some good points. At one point I've indeed fallen into the trap where I continued improving the mock object until it was a system of its own that was beginning to have bugs that had no relation to any real system the code was to run on. The mock thus became more of burden than a help, and after reading some posts of this "NoMock" movement, I realized they actually weren't even helping me. What's in a name, but what name would you suggest? :P
