Test-Driven Development (TDD)
Overview
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.
Violating the letter of the rules is violating the spirit of the rules.
Quick Start
- Write one failing test describing desired behavior
- Run it - confirm it fails for the right reason
- Write minimal code to pass
- Run it - confirm it passes
- Refactor if needed, keeping tests green

1coding-workflow
Use when user asks to build a feature, implement something new, or make significant code changes.
