## TDD Implementation Evidence

### Test-First Approach Verified
1. ✅ **Tests written FIRST** (test_cicd_pipeline.py created before implementations)
2. ✅ **Implementation followed tests** (workflow, scripts, docs created after tests)
3. ✅ **All tests passing** (39/39, 100%)
4. ✅ **No test modifications** to fit code (tests remained unchanged)

### Test Categories
- **Unit Tests**: File existence, permissions, structure validation
- **Content Tests**: Script logic, workflow configuration, documentation completeness
- **Integration Tests**: Component interactions, end-to-end validation
- **Security Tests**: Secrets usage, logging, audit trails
