TDD Cycle

RED Phase

Write a test that captures exactly one acceptance criterion
Run the test -- it MUST fail
Verify it fails for the RIGHT reason (not a syntax error)
Commit: test: add failing test for [criterion]

GREEN Phase

Write the MINIMUM code to make the test pass
Run the test -- it MUST pass
Verify only the target test turned green (no side effects)
Commit: feat: implement [criterion]

REFACTOR Phase

Clean up code while keeping ALL tests green
Remove duplication, improve naming, extract methods
Run full test suite -- ALL tests MUST pass
Commit: refactor: clean up [area]

Compliance Scoring

Score	Meaning
90-100	Exemplary TDD: all cycles followed correctly
70-89	Good TDD: minor deviations
50-69	Partial TDD: some implementation before tests
0-49	TDD violation: significant implementation without tests

Verification Methods

Git History Analysis: Test files must appear in commits before implementation files
Coverage Analysis: New code must have >90% test coverage
Commit Message Convention: RED/GREEN/REFACTOR phases identifiable in messages
