Write the test first. Watch it fail. Write minimal code to pass.
Core principle: If you didn't watch the test fail, you don't know if it tests the right thing.
NO PRODUCTION CODE WITHOUT A FAILING TEST FIRST
No exceptions without User permission.
Write one minimal test showing what should happen.
MANDATORY. Never skip. Confirm: Test fails (not errors) because feature is missing.
Write simplest code to pass the test. Do not over-engineer (YAGNI). Don't add features, refactor other code, or "improve" beyond the test.
MANDATORY. Confirm: Test passes and all other tests still pass.
After green only: Remove duplication, improve names, extract helpers. Keep tests green. Don't add behavior.
| Excuse | Reality |
|---|---|
| "Too simple to test" | Simple code breaks. Test takes 30 seconds. |
| "I'll test after" | Tests passing immediately prove nothing. |
| "Tests after achieve same goals" | Tests-after = "what does this do?" Tests-first = "what should this do?" |
| "Already manually tested" | Ad-hoc ≠ systematic. No record, can't re-run. |
