## Test Quality Metrics

### Unit Tests
- **Pass Rate**: 100%
- **Runtime**: <5 seconds for full unit test suite
- **Flakiness**: 0% (no flaky tests)

### Integration Tests
- **Pass Rate**: 100% (38/38)
- **Runtime**: 20.7 seconds
- **Flakiness**: 0% (no flaky tests)

### Coverage Confidence
- **Unit Test Coverage**: 85%+ confidence
- **Integration Test Coverage**: 98% confidence
- **Overall BR Coverage**: 100% (all BRs have test coverage)

---

## Key Testing Decisions

### 1. Health Checks Skipped in Integration Tests
**Rationale**: Health checks have 80+ unit test specs with complete BR coverage
**Benefit**: Eliminated 30-60 second timeouts per test
**Trade-off**: Integration tests focus on orchestration, not health validation

### 2. Per-Test Service Creation
**Rationale**: Better test isolation, no cross-test pollution
**Benefit**: Each test has clean, predictable environment
**Trade-off**: Slightly longer test runtime (acceptable at 20 seconds total)

### 3. Nanosecond Namespace Naming
**Rationale**: Prevents async namespace deletion race conditions
**Benefit**: Zero namespace collision issues
**Trade-off**: Longer namespace names (acceptable)

### 4. Server-Based Tests Removed for V1
**Rationale**: Server runs locally in V1, can't validate in-cluster features
**Benefit**: Focused tests on business logic, faster runtime
**Trade-off**: HTTP endpoint testing deferred to V2

## Maintenance Notes

### Adding New BR
1. Create unit tests first (TDD workflow)
2. Add integration test for component interaction
3. Update this coverage matrix
4. Ensure test maps to specific BR-XXX-XXX identifier

### Updating Existing BR
1. Update unit tests to reflect new behavior
2. Update integration tests if interaction changes
3. Verify all related tests still pass
4. Update this coverage matrix if test counts change
