The really obvious (and probably unhelpful) answer would be, "Just write the specs, dude." Expanding on that: there's nothing magic about the specs generated by the scaffold. I'm not even sure that they're great specs; they're just one opinion on how to test the default, plain-vanilla Rails actions. They'll stop passing the moment you change anything, and then you'll have to understand what they're doing and fix them. (And any non-trivial Rails app _will_ end up doing _something_ different than what the default scaffold controllers do.) I know in my case, I didn't understand the controller specs at all until I wrote some by hand. And then I wrote some more by hand, and understood them better. For a while I was using make_resourceful and mock_resourceful... I stopped, and rewrote those by hand, because there was too much magic and I couldn't follow what was going on. The end result was more lines of code, but it was just as good as what the plugins did and better-suited to my requirements, and I _understood_ it. That's worth more than the specs themselves are worth. So ignore the scaffold stuff, unless you want to look back at it as a reference example, and write some specs for the way your controller currently behaves. Do some mock objects for your models...or don't, as mocking too is just a matter of opinion. But test that the models are at least being called to find the right objects. Write at least one spec for the output of each controller action, making sure it renders what you want it to, and then write more if you think you need them. Keep doing this, and keep maintaining your specs the same way you'd refactor the actual code, and eventually you'll start to Get It. You'll feel good about your specs without having to ask anyone. Eventually you'll look at the example code and go, "Man, I can do better!" At that point, congratulations. You've cleared the level. Proceed to Level 2 -- whatever that may be for your particular style. Just don't stop learning things. If you stop, Donkey Kong keeps the girl.
