Since I don't come from a CS background (IS major at a business school), I never really knew much about strict testing methodologies except "make sure your shit ain't broke", and thus did the best I could early on by just testing the most probably use cases for my code. It's worked well enough for me that I still test code this way. This article makes me feel a little bit better about what I used to think was my own noobie way of testing :)
