Problems with TDD

This is the place to comment on my essay "Problems with TDD." In that essay I pointed out that there's still very little evidence that TDD is an effective development technique. I explained why TDD was not a good technique for me, and made the stronger claim that TDD is a weak development technique because it does not include essential unit tests. To show that it wasn't because I don't understand or practice TDD well enough, I pointed out worked-out examples done with TDD by two of the leading TDD experts. They contained implementation weakness which were not identified by TDD nor even mentioned by the implementors.
