The true TDD acolytes advocate a very idiosyncratic workflow, it's true.
I don't do this, but I also don't consider myself a TDD person. I value
tests a great deal, and put a lot of effort into them, but I don't write
trivial functions to get my tests to pass and then go back to change them.

But people whose opinion I value do advocate that, and it's possible that
in time I will understand their methods and use them myself.  Stranger
things have happened...
