## Troubleshooting Guide

### Common Issues

**Docker Socket Errors**
```bash
# Solution: Set proper Docker socket path
export DOCKER_HOST=unix:///home/cal/.docker/desktop/docker.sock
```

**Import Errors**  
```bash
# Solution: Ensure Python path includes project root
export PYTHONPATH=/mnt/NV2/Development/paper-dynasty/discord-app:$PYTHONPATH
```

**Slow Test Performance**
```bash
# Solution: Run fast tests only
python tests/players_refactor/run_tests.py fast
```

**Mock Setup Issues**
- Verify mock return values match expected format
- Check that all required methods are mocked
- Ensure async mocks use `AsyncMock`
- Validate mock call assertions

### Getting Help
1. Check test output for specific error messages
2. Review mock setup in `conftest.py`
3. Validate sample data structures
4. Compare with working test patterns
5. Check Discord.py and pytest documentation
