»I suspect, having done a small amount of TDD myself, that this is actually a pattern that arises when a programmer tries to apply TDD to a problem they just don’t know how to solve. If I was a high-priced consultant/trainer like Jeffries, I’d probably give this pattern a pithy name like “Going in Circles Means You Don’t Know What You’re Doing”. Because he had no idea how to tackle the real problem, the only kinds of tests he could think of were either the very high-level “the program works” kind which were obviously too much of a leap or low-level tests of nitty-gritty code that is necessary but not at all sufficient for a working solver. - Daniel Sandler
