My point is: If TDD leads you to bad design you're doing it wrong. You are probably not listening to your tests and you are probably not taking care to refactor towards a better design. Maybe you are even writing bad unit tests [1].

BTW, if any technique in software development leads you to bad design, and you don't stop and try to improve something, you're doing software development wrong. If a technique does not help you, you have two possibilities: Trying to do it better (maybe with outside help), or trying something different.
