Test Guardian Analysis

Verify existing test coverage and ensure tests will catch regressions during refactoring.

Analysis Checklist

Existing Coverage Analysis

• Map test coverage for all files in the refactoring scope
• Identify which behaviors are covered by unit vs integration tests
• Check for tests that depend on implementation details (brittle tests)
• Verify edge cases and error paths are covered

Gap Identification

• Find critical code paths with no test coverage
• Identify untested boundary conditions and error handling
• Detect missing integration tests between affected modules
• Check for untested concurrent or async behavior
