What Happens
- Define Test Cases - List all scenarios before writing anything
- RED - Write a failing test (proves the feature is missing)
- GREEN - Write minimal code to pass the test
- REFACTOR - Improve code while keeping tests green
- REPEAT - Move to next test case
- VERIFY - Check coverage meets 80%+ target
The Cycle
RED → GREEN → REFACTOR → REPEAT
RED: Write a failing test
GREEN: Write minimal code to pass
REFACTOR: Improve code, keep tests passing
REPEAT: Next test case
When to Use
- Implementing new features
- Fixing bugs (write test that reproduces bug first)
- Building critical business logic
- Adding new functions or components
- Refactoring existing code (write characterization tests first)
