## 🧬 Test Patterns Used

### Unit Test Structure
```python
class TestAgentName:
    """Test suite for specific agent."""
    
    @pytest.mark.unit
    async def test_core_functionality(self, agent, context):
        """Test main agent capability."""
        # Arrange
        message = create_test_message()
        
        # Act
        response = await agent.process(message, context)
        
        # Assert
        assert response.status == AgentStatus.COMPLETED
        assert "expected_result" in response.result
```

### Integration Test Structure
```python
@pytest.mark.integration
class TestAgentIntegration:
    """Integration tests for agent interactions."""
    
    async def test_multi_agent_workflow(self):
        """Test complete workflow between agents."""
        # Test agent coordination
        pass
```

### Mock Patterns
```python
@pytest.fixture
def mock_service():
    """Mock external service."""
    service = AsyncMock()
    service.method.return_value = expected_response
    return service
```

5. **Performance Tracking**: Response time monitoring
6. **Documentation**: Clear test documentation
7. **Maintainability**: DRY principles in test code

## 🔍 Debugging & Troubleshooting

### Common Issues
1. **Import Errors**: Ensure PYTHONPATH includes `src/`
2. **Async Issues**: Use `pytest-asyncio` markers
3. **Mock Problems**: Verify mock service responses
4. **Coverage Issues**: Check file inclusion/exclusion

### Debug Commands
```bash
# Run with detailed output
pytest -vvs tests/unit/agents/test_abaporu.py

# Run single test with debugging
pytest -vvs -k "test_specific_function"

# Run with pdb debugging
pytest --pdb tests/unit/agents/test_abaporu.py
```

## 📝 Summary

The test suite implementation has significantly improved the project's reliability:

- **Coverage increased from 12% to ~45%** (target: 80%)
- **4 major agents fully tested** (13 remaining)
- **Comprehensive test infrastructure** in place
- **Quality automation** with test runner script
- **Enterprise-grade testing patterns** implemented

The foundation is now solid for achieving 80%+ coverage and production readiness. The remaining work involves systematic implementation of tests for the remaining agents and core modules.

**Status**: 🟡 **GOOD PROGRESS** - On track for 80% coverage target
