 - Slow execution (5-10 seconds per test with real I/O)
 
 **After Mocking Tests**:
-- ✅ 15 new tests with 100% pass rate
-- ✅ 0.83 second execution (15-20x faster than real I/O)
-- ✅ Zero external dependencies (no database/file setup)
-- ✅ 0% flaky test rate (deterministic mocking)
-- ✅ 90% test code coverage
