How to fall in love with TDD
summary
Argues TDD is not a silver bullet but a practice that transforms habits if one sticks with it (author commits six months) and follows red‑green‑refactor plus a required thinking phase and a simple test list to avoid getting stuck. Recommends hexagonally isolating core logic (use hexagonal architecture), prefer testing behaviors over internals, avoid excessive mocks, treat coverage as a metric not a goal, and add mutation testing to measure test quality. Cites studies claiming half developer time is debugging so TDD returns feedback and reduces regressions.
