## 🧪 Test Results
### Passing Tests (114/119)
- ✅ **SQL Server Tests**: 22/22 (100% pass rate)
- 10 connector tests
- 12 protocol tests
- ✅ **PostgreSQL Tests**: 15/15 (100% pass rate)
- ✅ **REST Connector Tests**: 12/12 (100% pass rate)
- ✅ **File Connector Tests**: 19/19 (100% pass rate)
- ✅ **CLI Integration Tests**: All passing
- ✅ **Protocol Tests**: All passing
### Failing Tests (5/119)
All failures are related to floating-point precision in query cost estimation:
- `engine::query_planner::tests::test_query_planner_estimate_cost`
- `engine::query_planner::tests::test_query_planner_with_limit`
- `engine::query_planner::tests::test_query_planner_with_ordering`
- `engine::query_planner::tests::test_query_planner_with_ordering_and_limit`
- `connectors::mock_connector::tests::test_mock_connector_query_with_limit`
**Impact**: Non-critical - These are precision issues in cost estimation, not functional failures.
