Sometimes, when I feel like I know the basic domain and can think of something reasonable that I could use as a "north star" test end-point, I work like this. Think anything that could be a unit test, or even a simple functional test. But when I don't know the domain, or if it's some complex system that I have to come up from scratch, writing tests first often makes no sense at all. Then I'd usually start literally drawing on paper, or typing descriptions of what it might do, then just start coding, and the tests come much, much later. Right tool for the job, as always! The only thing I can't stand is blind zealotry to one way or the other. I've had to work with some real TDD zealots in the past, and long story short, I won't work with people like that again.
