If words don't mean anything then of cause there is no difference. You might as well program in brainf*ck -- hey, it is turing complete, so same diff.

Personally, I like seeing "dummy" name passed into a function and understanding just from the name that no methods are expected to called on it during the test. Or seeing "fake_something " and understanding that a manual (perhaps test-specific) implementation is used. It is a minor point but such chunking is universally useful (there is enough stuff to keep track of).

My original point was that the architecture can facilitate so called classical unit tests over mocks (make the latter less necessary) https://martinfowler.com/articles/mocksArentStubs.html#Class...
