Test Coverage Review

Review code from a testing perspective.

Review Checklist

Unit Test Coverage

• Verify all public functions have unit tests
• Check boundary conditions and edge cases are tested
• Look for missing null/empty/error path tests
• Verify assertions are meaningful (not just "no exception thrown")

Integration Test Coverage

• Check critical user flows have integration tests
• Verify API endpoints are tested end-to-end
• Look for missing database interaction tests
• Check external service integration points
