🧪 Test Deployment Strategy Selection:
- Create sample changes with varying risk levels
- Verify appropriate deployment strategies are selected
- Confirm approval workflows trigger correctly
📡 Verify Monitoring Configuration:
- Deploy a controlled change
- Inject simulated anomalies
- Confirm detection and alerting functions
⏪ Test Automated Rollback:
- Deploy a change with embedded performance issue
- Verify automatic detection and rollback
- Confirm proper recording of incident

❓ Troubleshooting

Issue	Resolution
📊 Inaccurate risk scores	Verify risk profile configuration and adjust weights according to your environment
🚨 False positive anomalies	Tune sensitivity settings and increase learning period for baseline establishment
🔗 Missing dependency detection	Ensure full repository history is available and dependency mapping is enabled
⏱️ Delayed risk alerts	Check notification configuration and alert routing settings
📉 Model drift over time	Schedule regular model retraining and validation against known outcomes
