+#### Test Collecting Volume Backend Store Driver
+
+**Given** [Prerequisite](#prerequisite).
+**And** Create one volume using V1 engine.
+        Create two volume using V2 engine.
+**And** [Deploy upgrade responder stack](https://github.com/longhorn/longhorn/tree/master/dev/upgrade-responder).  
+
+**When** Wait 1~2 hours for collection data to send to the influxDB database.  
+
+**Then** `longhorn_volume_backend_store_driver_v1_count` should exist the influxDB database.  
+         `longhorn_volume_backend_store_driver_v2_count` should exist the influxDB database.
