TDD Master Workflow Skill

This skill provides comprehensive TDD guidance.

Red-Green-Refactor Cycle

1. Write a failing test (Red)
2. Make it pass with minimal code (Green)
3. Refactor while keeping tests passing
4. Repeat

Test Organization

• Unit tests: fast, isolated, deterministic
• Integration tests: real dependencies, slower
• Contract tests: API boundaries
• E2E tests: critical user journeys

Advanced Patterns

• Test doubles: mocks, stubs, fakes, spies
• Property-based testing
• Mutation testing
• Contract testing (Pact)
• Snapshot testing for UI

Workflow Integration

• Pre-commit test runs
• CI pipeline stages
• Coverage thresholds
• Flaky test quarantine
