> > "But otherwise, what exactly are you testing?" > That's a great point. I don't want to be specing Rails if it is not easily separable for testing already. In theory, I would like to have true unit tests for my models. However, in practice, some of my models are coupled to some degree.
Generally speaking, I prefer not to mock/stub Rails internals to test my app. I don't find mocking/stubbing *my* code -- that is fine with me. But the internals of Rails are *not* what I'm trying to test. In particular, I found that mocking/stubbing with has_many :through was far from simple. I fired up ruby-debug (highly recommended!) and everything, but realized it was too much effort and too little time. In this sense, my experience is probably similar to Scott's (above post). My Goal model, for example, checks to see how many Contributions it has. It uses a has_many :through (hmt) association. Despite the helpful words of some posters in this thread, I couldn't find a way to effectively spec the hmt association. By the time I had stubbed out enough to make it a true unit test, I was no longer testing what I wanted to test -- namely, that the association itself. Maybe this was a wake up call that there was not point in trying to test that at a unit level? In any case, I've got some conditional logic that connects with the association, so I definitely need to test that, at least. In the end, I just tested the "interaction" between models. In this folder, I test how models in my app work together. I didn't think these specs fit under 'model' because they are testing more than one model. So I put them in a new directory called 'model_integration' folder under the 'spec' directory. I came up with this name on my own intuition, and I can't blame anyone else if this is a bad idea. I wasn't sure if 'model_interaction' would have been a better name, but from what I gather, 'interaction' is a special term when it comes to testing. Suggestions? -DJ
