## Testing Philosophy

### NO MOCKING Policy

**Tier 2 (Integration) & Tier 3 (E2E)** tests use 100% real infrastructure:

- ✅ Real Ollama LLM (llama3.2:1b - FREE inference)
- ✅ Real DataFlow persistence (SQLite/PostgreSQL)
- ✅ Real Redis cache (warm tier)
- ✅ Real file system (checkpoints, temp files)
- ✅ Real HTTP requests (tool calling)
- ✅ Real subprocess execution (bash tools)
- ✅ Real interrupt handlers (signals, timeouts)
- ✅ Real workflow execution (Kailash Core SDK)

**Why?**
- Catches real-world integration issues
- Validates production-ready behavior
- Tests actual performance characteristics
- Ensures cross-component compatibility

## Troubleshooting

### Common Issues

1. **Ollama not running**
   ```
   Error: Could not connect to Ollama
   Solution: ollama serve
   ```

2. **Redis not available**
   ```
   Error: Redis connection refused
   Solution: redis-server &
   ```

3. **DataFlow model conflicts**
   ```
   Error: NodeRegistry collision
   Solution: Use unique model names per test (timestamp suffix)
   ```

4. **Test timeout**
   ```
   Error: Test exceeded 120s timeout
   Solution: Increase timeout with @pytest.mark.timeout(300)
   ```

### Debug Mode

```bash
# Run with verbose output
pytest tests/e2e/autonomy/ -vvv --log-cli-level=DEBUG

# Run single test with full trace
pytest tests/e2e/autonomy/test_checkpoint_e2e.py::test_auto_checkpoint_during_execution -xvs
```
