Snapshot Testcase-1
Create/Restore Snapshot of PVC using single datastore preference
Steps
1. Assign Tag rack-1, Category "cns.vmware.topology-preferred-datastores" to datastore
specific to rack-1 (ex- NFS-1)
2. Create SC with Immediate binding mode and allowed topologies set to
region1 > zone1 > building1 > level1 > rack > rack1 in the SC
3. Create PVC-1 with the above SC
4. Wait for PVC-1 to reach Bound state.
5. Create a VolumeSnapshot class.
6. Create a volume-snapshot using the above snapshot-class and pvc-1
7. Use the same snapshot to create PVC-2
8. Wait for PVC-2 to reach Bound state.
9. Create POD using PVC-2
10. Verify volume should be provisioned on the preferred datastore.
11. Describe PV-2 and verify node affinity details, and verify POD should come up on same node as
mentioned in PV2
12. Perform Cleanup. Delete Snapshot, Pod, PVC, SC, volume-snapshot and VolumeSnapshot class.
13.Remove datastore preference tags as part of cleanup.

/*
Testcase-4
Topology Snapshot workflow for statefulset
1. Assign Tag rack-3, Category "cns.vmware.topology-preferred-datastores" to datastore specific to
rack-3 (ex- NFS-3)
2. Create SC with Immediate binding mode and allowed topologies set to rack-3 in the SC
3. Create a statefulset with 3 replicas using above SC
4. Wait for pvcs to be in Bound state
5. Wait for pods to be in Running state
6. Describe PV and verify node affinity details should contain specified allowed topology details.
7. Verify volume should be provisioned on the selected preferred datastore of rack-3.
8. Create snapshot on 3rd replica's PVC.
9. Scale down the statefulset to 2
10. Delete the PVC on which snapshot was created
11. PVC delete succeeds but PV delete will fail as there is snapshot - expected
12. Create a new PVC with same name (using the snapshot from step-8) - verify a new PV is created
13. Describe PV and verify node affinity details should contain specified allowed topologies.
14. Verify volume should be provisioned on the selected preferred datastore.
15. Scale up the statefulset to 3
16. Verify if the new pod attaches to the PV created in step-13
17. Describe PV and verify node affinity details should contain specified allowed details.
18. Verify volume should be provisioned on the selected preferred datastore.
19. Perform Cleanup. Delete StatefulSet, PVC,PV
20. Remove datastore preference tags as part of cleanup.
