## Coverage Gaps

### Known Limitations

1. **Load Testing**: No tests for extreme load (1000+ concurrent requests)
   - **Impact**: Medium
   - **Mitigation**: Planned for v1.1.0

2. **Disaster Recovery**: Limited testing of backup/restore under load
   - **Impact**: Low
   - **Mitigation**: Manual testing procedures documented

3. **Network Partitions**: Limited testing of split-brain scenarios
   - **Impact**: Low (distributed locking mitigates)
   - **Mitigation**: Planned for v1.2.0

4. **Security Penetration Testing**: No automated penetration tests
   - **Impact**: Medium
   - **Mitigation**: Annual security audit

### Planned Enhancements

- [ ] Chaos engineering tests (inject failures)
- [ ] Load testing with 10,000+ concurrent operations
- [ ] Extended disaster recovery scenarios
- [ ] Fuzz testing for API endpoints
- [ ] Performance regression detection

### v1.1.0 (Next Release)

- **Load Testing Suite**: 1000+ concurrent operations
- **Chaos Engineering**: Inject random failures

- **Compliance Testing**: GDPR, SOC2 compliance validation
- **Visual Regression Testing**: UI component testing

### v2.0.0 (Future)

- **AI-Powered Test Generation**: Generate tests from user scenarios
