People tend to forget that TDD isn't a 3-step process. Even this article makes that mistake. Write a test, pass that test, refactor. People generally forget the refactoring step. Basically though, if you find your test difficult to write, there is a problem, and it's not with the test. And that should be your sign that you either don't understand the problem, or you are trying to do too much. Now, this is hard. It's hard to accept that way of thinking. But the end result has always been cleaner, better code in my experience. It's not always the obvious way, but it's the best way.
