Test-Driven Development
Iron Law
No production code without a failing test first.
No exceptions. Not for "simple" changes. Not for "obvious" fixes. Not under time pressure.
RED-GREEN-REFACTOR
1. RED — Write a failing test
- One minimal test with a clear name
- Use real code, not mocks (unless unavoidable)
- Watch it fail. Verify it fails for the RIGHT reason.
2. GREEN — Write minimal code to pass
- Only enough code to make the test pass
