>Specifically, when given a very well defined problem-set Agree. My most successful implementation of TDD was for a project where a front end was developed by a third party and I developed the API that the front end would consume. As part of the project, I had to define the API behaviors and data structures anyway. It was the easiest integration I've ever worked on.
