majiayu000 TDD Integration Testing
Enforce strict Test-Driven Development using the Red-Green-Refactor cycle with dedicated subagents.
Mandatory Workflow
Every new feature MUST follow this strict 3-phase cycle. Do NOT skip phases.
Phase 1: RED - Write Failing Test
🔴 RED PHASE: Delegating to tdd-test-writer...
Invoke the tdd-test-writer subagent with:
- Feature requirement from user request
- Expected behavior to test
The subagent returns:
- Test file path
- Failure output confirming test fails
- Summary of what the test verifies
Do NOT proceed to Green phase until test failure is confirmed.
Phase 2: GREEN - Make It Pass
🟢 GREEN PHASE: Delegating to tdd-implementer...
Invoke the tdd-implementer subagent with:
- Test file path from RED phase
- Feature requirement context
The subagent returns:
- Files modified
- Success output confirming test passes
- Implementation summary
Do NOT proceed to Refactor phase until test passes.
Phase 3: REFACTOR - Improve
🔵 REFACTOR PHASE: Delegating to tdd-refactorer...
Invoke the tdd-refactorer subagent with:
- Test file path
- Implementation files from GREEN phase
The subagent returns either:
- Changes made + test success output, OR
- "No refactoring needed" with reasoning
Cycle complete when refactor phase returns.
Multiple Features
Complete the full cycle for EACH feature before starting the next:
Feature 1: 🔴 → 🟢 → 🔵 ✓ Feature 2: 🔴 → 🟢 → 🔵 ✓ Feature 3: 🔴 → 🟢 → 🔵 ✓
Phase Violations
Never:
- Write implementation before the test
- Proceed to Green without seeing Red fail
- Skip Refactor evaluation
- Start a new feature before completing the current cycle
