TDD Methodology Applied

For every feature:

  1. Write Tests First ✅

    • Comprehensive test coverage
    • Edge cases included
    • Error conditions tested

  2. Watch Tests Fail ✅

    • Verified test logic
    • Confirmed failure modes

  3. Implement Feature ✅

    • Minimal code to pass tests
    • Proper error handling
    • Full documentation

  4. Watch Tests Pass ✅

    • All tests green
    • No regressions

  5. Refactor ✅

    • Clean, maintainable code
    • Idiomatic for each platform
    • Performance optimized
