That supposes to have a clear idea of what you’re going to code. Otherwise, it’s a lot of time wasted to constantly rewrite both the code and tests as you better understand how you’re going to solve the task while trying. I guess it works for very narrowed tasks rather than opened problems.
The only projects I’ve ever found interesting in my career was the stuff where nobody had any idea yet how the problem was going to be handled, and you’re right that starting with tests is not even possible in this scenario (prototyping is what’s really important). Whenever I’ve written yet another text/email/calling/video Skype clone for yet another cable company, it’s possible to start with tests because you already know everything that’s going into it.
