-1. Use the test button on the trigger page. Flashduty receives an Info alert titled `Kener test notification`. The test request is a fixed body built into Kener whose status is randomly `TRIGGERED` or `RESOLVED`; either way it creates only this separate Info alert, which never recovers, so close it manually in Flashduty after verifying. Flashduty recognizes the test request by `alert_incident_id` and the two threshold fields of the template above
+1. Use the test button on the trigger page and confirm that Kener reports the request as sent. The test request is a fixed body built into Kener (alert ID `1`, severity `WARNING`, status randomly `TRIGGERED` or `RESOLVED`), and Flashduty handles it like any other alert: `TRIGGERED` creates or updates a Warning alert with Alert Key `1`, and `RESOLVED` recovers that alert, or creates nothing when no such alert is open. If the alert is still open after verifying, close it manually in Flashduty
 2. Make a monitored service fail and confirm that an active alert appears in Flashduty once the failure threshold is reached
 3. Restore the service and confirm that the alert recovers once the success threshold is reached
