Review HTML coverage report visually 2. Deploy to staging for integration testing 3. Monitor correlation IDs in production logs ### Short-Term 1. Add tests for validator methods (lines 236-238) - optional 2. Document error response format for API consumers 3. Set up coverage tracking in CI/CD ### Long-Term 1. Implement mutation testing 2. Add performance benchmarks 3. Set up coverage trend monitoring ## Conclusion The financial endpoints have **excellent test coverage** (97.73%) with all critical error handling paths verified. The original 500 error issue has been fully resolved with: - Proper error status codes - Correlation IDs for tracking - User-friendly error messages - Comprehensive test coverage **Status: PRODUCTION READY ✓** --- ## Additional Resources - Test files: `/Users/darrenmorgan/AI_Projects/hostaway-mcp/tests/` - Source code: `/Users/darrenmorgan/AI_Projects/hostaway-mcp/src/api/routes/financial.py` - HTML report: `/Users/darrenmorgan/AI_Projects/hostaway-mcp/htmlcov/financial/index.html` For questions or issues, refer to the detailed coverage reports listed above.
