I agree that the use of test helpers if probably an indication of a lack of fluidity in the API, but I’m not a fan of absolutes so to say that would *always* be the case doesn’t sit right with me.

I have noticed that when I create mock objects in my specs, helpers can be useful to make the construction of the mocks more fluid and easy on the eye. In some cases, that’s a sign that the objects I am mocking have an unclear interface but other times it’s simply a reaction to the fact rspec only provides a single, simple, way to construct mocks and sometimes you just need more.

I have to sort it out immediately, preferably before it happens. When you’re over here for your UK tour maybe you can show me how to let go a bit more… :)

I completely agree with your notion that need-for-test-helper is the scent of weak design. One of the things I’ve been thinking of doing for my next video set is an attempt to maximize all such ideas — the ones that fall out of TDD, that is — during a reasonably rich set of TDD videos. – GeePaw

Thanks for the great thoughts and feedback.

I definitely agree that the test helpers are an indication of possible api problems. One technique that I use is to build test helpers in the specs, knowing that they most likely are production code waiting to find a place. :)
