What got me out of TDD zealotry is the enormous cost of really testing software well, I mean all branches, all sides of all conditions, large amounts of input space coverage. Then that coupled with the fact that specifications change constantly and relentlessly, invalidating some percentage of all of your cases. I agree with the sentiment that got me into testing in the first place: software is complicated and hard to modify without breaking something. But, TDD for sure isn’t the answer to that problem.
