https://www.jamesshore.com/v2/blog/2005/microsoft-gets-tdd-completely-wrong Nice old article on Microsoft getting TDD wrong in ways that many others have mistaken, too. Essentially, they suggested "waterfall-style TDD" which is a contradiction of terms. #TDD is meant to be fast and iterative. It is an absolute joy in #Clojure Cider (and presumably other toolings and languages), where you re-run the failing test with every re-evaluation, watching for that joyful green light to say that now you've passed. https://www.jamesshore.com/v2/blog/2005/microsoft-gets-tdd-completely-wrong
