Test Statistics

• Total Tests: 22 test functions
• All Tests: PASSING ✅
• Total Packages: 3
• Coverage Target: 90%+ overall, 80%+ per file
• Achievement: 100% overall, 100% per file ✅✅

Testing Approach

1. Baseline Analysis: Identified main() function as only uncovered code (0% coverage)
2. Test Implementation: Created TestMainFunction with stdout redirection
3. Verification: All tests pass with 100% coverage across all packages
4. Quality: Tests validate actual behavior, not just coverage metrics
