Refactoring to simplify code leads to
cleaner designs. If nothing else, you should get a better feel for what makes a clean design. On the other hand, if by ¡°design¡± you¡¯re thinking mainly systems-level, I don¡¯t really see TDD as helping.?

JB,I'm quite surprised by your second claim, that "One can learn designskill by practising TDD".Can you support that?KOn Tue, Jul 4, 2023 at 2:43?PM J. B. Rainsberger <me@...> wrote:
I am surprised to encounter so many people who claim something like this:
"You must understand how to design before you can practise TDD well."
I say the following in response:
- Practising TDD "poorly" still helps many programmers
- One can learn design skill by practising TDD, and I consider this a kind of pracitisng TDD "well"
- Your claim, framed that way, needlessly scares programmers away from TDD who need it
Practising TDD well and improving design skill forms an amplifying feedback loop, don't you think?
