    Scenario-Driven Testing

    Simulate Real-World Problems

    Define edge cases and failure scenarios in YAML. Test how your CSMS handles connection issues, timeouts, and offline charge points—before production.

    Connection Recovery

    Simulate charge point reconnection after network failure. Test how your CSMS handles BootNotification after disconnect.

    scenario.yaml
    Connection Recovery
    # Test CSMS reconnection handling
    name: "Connection Recovery Test"
    target: "wss://csms.example.com/ocpp"
    chargers:
      count: 5
      id_prefix: "RECOVER"
      vendor: "mockpoint"
      model: "Simulator-v1"
    steps:
      # Initial connection
      - action: bootNotification
      - action: statusNotification
        status: "Available"
      - action: heartbeat
      
      # Simulate network interruption (sleep)
      - action: sleep
        duration_ms: 5000
        
      # Reconnection sequence
      - action: bootNotification
      - action: statusNotification
        status: "Available"
      - action: heartbeat
      - action: heartbeat
