- Created test_database_url_validation.py for static code analysis - Created test_runtime_errors.py for runtime error verification - Created TEST_RESULTS.md with comprehensive test documentation - All 7 Python scripts verified to use safe 'CHANGE_ME' fallback - Confirmed no hardcoded production credentials remain in code - Scripts properly fail with clear authentication errors - Test coverage: 7/7 scripts passed (100%) Security validation complete for CWE-798 remediation.
