I saw a tweet titled something like "TDD as if you mean it". I'm sorry to whoever posted it. I can't find the link, now. The gist was that you start with only your tests and extrude a design from passing tests.
I'm experimenting with it and it's kind of interesting.
I think it might seem even less comfortable for someone who hasn't made the TDD mindset shift than "regular" TDD.
I'm digging it, though.
