----
+## CI/CD Integration
 
-## 🔗 **Integration Testing**
+### GitHub Actions Example
 
-### **Cross-Phase Workflows**
-1. **End-to-End Job Execution**
-   - Client creates job → Agent matches → Escrow funded → Work completed → Payment released
-
-2. **Consensus with Network**
-   - Validators discover peers → Form consensus → Propagate blocks → Handle partitions
-
-3. **Economics with Agents**
-   - Agents earn rewards → Stake tokens → Reputation affects earnings → Economic incentives
-
-4. **Contracts with All Layers**
-   - Escrow created → Network validates → Economics processes → Agents participate
-
-### **Test Scenarios**
-```python
-@pytest.mark.asyncio
-async def test_end_to_end_job_execution_workflow(self):
-    """Test complete job execution workflow across all phases"""
-    # 1. Client creates escrow contract
-    success, _, contract_id = mock_escrow.create_contract(...)
-    
-    # 2. Find suitable agent
-    agents = mock_agents.find_agents("text_generation")
-    
-    # 3. Network communication
-    success, _, _ = mock_protocol.send_message(...)
-    
-    # 4. Consensus validation
-    valid, _ = mock_consensus.validate_transaction(...)
-    
-    # 5. Complete workflow
-    assert success is True

-1. **Use descriptive test names**
-2. **Arrange-Act-Assert pattern**
-3. **Test both success and failure cases**
-4. **Mock external dependencies**
-5. **Use fixtures for shared setup**
-6. **Add performance assertions**
-7. **Include security edge cases**
-8. **Document test purpose**

-## 🚨 **Troubleshooting**
-
-### **Common Issues**
-
-#### **Import Errors**
-```bash
-# Add missing paths to sys.path
-export PYTHONPATH="/opt/aitbc/apps/blockchain-node/src:$PYTHONPATH"
-```
-
-#### **Mock Mode Issues**
-```bash
-# Disable mock mode for integration tests
-export AITBC_MOCK_MODE=false
-python -m pytest test_phase_integration.py -v
-```
-
-#### **Performance Test Timeouts**
-```bash
-# Increase timeout for slow tests
-python -m pytest test_performance_benchmarks.py -v --timeout=300
-```
-
-#### **Security Test Failures**
-```bash
-# Run security tests with verbose output
-python -m pytest test_security_validation.py -v -s --tb=long
-```
-
-### **Debug Mode**
-```bash
-# Run with debug logging
-export AITBC_LOG_LEVEL=DEBUG
-python -m pytest test_mesh_network_transition.py::test_consensus_initialization -v -s
-```

+## Troubleshooting
 
-## 🎯 **Success Criteria**
+### Common Issues
 
-### **Test Coverage Goals**
-- **Unit Tests**: 95%+ code coverage
-- **Integration Tests**: All critical workflows
-- **Performance Tests**: All benchmarks met
-- **Security Tests**: All attack vectors covered
+1. **Import Errors**
+   ```bash
+   # Ensure PYTHONPATH is set
+   export PYTHONPATH="${PYTHONPATH}:$(pwd)"
+   
+   # Or install in development mode
+   pip install -e .
+   ```
 
-### **Quality Metrics**
-- **Test Reliability**: < 1% flaky tests
-- **Execution Time**: < 10 minutes for full suite
-- **Maintainability**: Clear, well-documented tests
-- **Reproducibility**: Consistent results across environments
+2. **Database Connection Errors**
+   ```bash
+   # Check if PostgreSQL is running
+   pg_isready -h localhost -p 5432
+   
+   # Create test database
+   createdb -h localhost -p 5432 aitbc_test
+   ```
 
----
+3. **Redis Connection Errors**
+   ```bash
+   # Check if Redis is running
+   redis-cli ping
+   
+   # Use correct database
+   redis-cli -n 1 FLUSHDB
+   ```
 
-**🎉 This comprehensive test suite ensures the AITBC mesh network implementation meets all functional, performance, and security requirements before production deployment!**
+4. **Test Timeouts**
+   ```bash
+   # Increase timeout for slow tests
+   pytest --timeout=600
+   
+   # Run tests sequentially
+   pytest -n 0
+   ```
+
+5. **Port Conflicts**
+   ```bash
+   # Kill processes using ports
+   lsof -ti:8001 | xargs kill -9
+   lsof -ti:8002 | xargs kill -9
+   ```
+
+### Debugging Tests
+
+```bash
+# Run with verbose output
+pytest -v -s
+
+# Stop on first failure
+pytest -x
+
+# Run with pdb on failure
+pytest --pdb
+
+# Print local variables on failure
+pytest --tb=long
+
+# Run specific test with debugging
+pytest tests/unit/test_coordinator_api.py::TestJobEndpoints::test_create_job_success -v -s --pdb
+```
+
+### Performance Issues
+
+```bash
+# Profile test execution
+pytest --profile
+
+# Find slowest tests
+pytest --durations=10
+
+# Run with memory profiling
+pytest --memprof
+```
+
+### Test Data Issues
+
+```bash
+# Clean test database
+psql -h localhost -U test -d aitbc_test -c "DROP SCHEMA public CASCADE; CREATE SCHEMA public;"
+
+# Reset Redis
+redis-cli -n 1 FLUSHALL
+
+# Regenerate test fixtures
+python tests/generate_fixtures.py
+```
+
+## Best Practices
+
+1. **Write Isolated Tests**: Each test should be independent
+2. **Use Descriptive Names**: Test names should describe what they test
+3. **Mock External Dependencies**: Use mocks for external services
+4. **Clean Up Resources**: Use fixtures for setup/teardown
+5. **Test Edge Cases**: Don't just test happy paths
+6. **Use Type Hints**: Makes tests more maintainable
+7. **Document Complex Tests**: Add comments for complex logic
+
+## Contributing
+
+When adding new tests:
+
+1. Follow the existing structure and naming conventions
+2. Add appropriate markers (`@pytest.mark.unit`, etc.)
+3. Update this README if adding new test types
+4. Ensure tests pass on CI before submitting PR
+5. Add coverage for new features

+
+2. Start a gossip relay service:
+   python -m aitbc_chain.gossip.relay --port 7070
+
+3. Configure P2P discovery:
+   - Add peer list to configuration
+   - Ensure ports are accessible between nodes
+
+4. For production deployment:
+   - Use Redis as gossip backend
+   - Configure proper network addresses
+   - Set up peer discovery mechanism
+
+Current status: Nodes are running independently with memory backend.
