# Test-Driven Development ## The Cycle **RED → GREEN → REFACTOR** Never skip RED. Never write code before a failing test exists. ## Steps 1. **Write the failing test** — specific, tests one behavior 2. **Run it and confirm it fails** — with the right error message 3. **Write minimal code to make it pass** — no more than needed 4. **Run it and confirm it passes** 5. **Refactor if needed** — tests still pass after refactor 6. **Commit** — small, frequent commits ## Anti-Patterns to Avoid - Writing implementation before tests - Tests that pass without any implementation (false green) - Testing implementation details instead of behavior - One giant test instead of small focused tests - Skipping the refactor step ## Verification Command Always show the exact command to run tests and expected output at each RED/GREEN step.
