## Test Execution

### Quick Test (Core Only)
```bash
pytest tests/0.core/ -v
```

### Full Test Suite
```bash
python tests/runner.py
```

### Performance Tests Only
```bash
pytest -m xwjson_performance -v
```

### Stress Tests Only
```bash
pytest tests/2.integration/scenarios/test_stress_*.py -v
```

## Test Results

All tests are designed to:
- ✅ Pass with proper dependencies installed
- ✅ Skip gracefully when dependencies unavailable
- ✅ Provide clear error messages
- ✅ Test edge cases and error conditions
- ✅ Verify performance targets
- ✅ Stress test to maximum capacity

## Next Steps

1. Run full test suite: `python tests/runner.py`
2. Fix any failing tests
3. Add more edge case tests as needed
4. Monitor performance benchmarks
5. Update tests as features evolve
