I would like to set up a return value
_stubRepository.Stub(Contains(null)).IgnoreArguments().Return(true);
but then in a specific test, override that expectation to return false.
Something like:
_stubRepository.ClearExpectations(); //<- this does not exist, I'm just making something up
_stubRepository.Stub(Contains(null)).IgnoreArguments().Return(false);
Notice, I do not want the expectation to return false on the second call, I want to override the first expectation.
This would help simplify my testing scenario greatly.
There are three ways:
You can reset the expectations by using BackToRecord
I have to admit that I never really used it because it is awkward.
// clear expectations, an enum defines which
_stubRepository.BackToRecord(BackToRecordOptions.All);
// go to replay again.
_stubRepository.Replay();
Edit: Now I use it sometimes, it is actually the cleanest way. There should be an extension method (like Stub) which does it - I think it just got forgotten. I would suggest to write your own.
You can use Repeat.Any()
It 'breaks' the order of the stubbed definition and "overrides" previous definitions. But it's somehow implicit. I use it sometimes because it is easy to write.
_stubRepository.Stub(x => x.Contains(null))
.IgnoreArguments()
.Return(false)
.Repeat.Any();
You can create a new mock
Trivial, but explicit and easy to understand. It is only a problem if you want to keep plenty of definitions and only change one call.
_stubRepository = MockRepository.GenerateMock<IRepository>();
_stubRepository.Stub(x => x.Contains(null))
.IgnoreArguments()
.Return(false);
