Manual Testing Requirements for Velero

Although we have automated unit and end-to-end tests, there is still a need for Velero to undergo manual tests during a release. This document outlines the manual test operations that Velero needs to correctly perform in order to be considered ready for release.

Current test cases

The following are test cases that are currently performed as part of a Velero release.

Install

• Verify that Velero CRDs are compatible with the earliest and latest versions of Kubernetes that we support:
  • Kubernetes v1.16
  • Kubernetes v1.22

Upgrade

• Verify that Velero upgrade instructions work

Basic functionality

The “Backup and Restore” test cases below describe general backup and restore functionality that needs to run successfully on all the following providers that we maintain plugins for:

• AWS
• GCP
• Microsoft Azure
• VMware vSphere

Backup and Restore

• Verify that a backup and restore using Volume Snapshots can be performed
• Verify that a backup and restore using Restic can be performed
• Verify that a backup of a cluster workload can be restored in a new cluster
• Verify that an installation using the latest version can be used to restore from backups created with the last 3 versions.
  • e.g. Install Velero 1.6 and use it to restore backups from Velero v1.3, v1.4, v1.5.

Working with Multiple Providers

The following are test cases that exercise Velero behaviour when interacting with multiple providers:

• Verify that a backup and restore to multiple BackupStorageLocations using the same provider with unique credentials can be performed
• Verify that a backup and restore to multiple BackupStorageLocations using different providers with unique credentials can be performed
• Verify that a backup and restore that includes volume snapshots using different providers for the snapshots and object storage can be performed
  • e.g. perform a backup and restore using AWS for the VolumeSnapshotLocation and Azure Blob Storage as the BackupStorageLocation

Future test cases

The following are test cases that are not currently performed as part of a Velero release but cases that we will want to cover with future releases.

Schedules

• Verify that schedules create a backup upon creation and create Backup resources at the correct frequency

Resource management

• Verify that deleted backups are successfully removed from object storage
• Verify that backups that have been removed from object storage can still be deleted with velero delete backup
• Verify that Volume Snapshots associated with a deleted backup are removed
• Verify that backups that exceed their TTL are deleted
• Verify that existing backups in object storage are synced to Velero

Restic repository test cases

• Verify that restic repository maintenance is performed as the specified interval

Backup Hooks

• Verify that a pre backup hook provided via pod annotation is performed during backup
• Verify that a pre backup hook provided via Backup spec is performed during backup
• Verify that a post backup hook provided via pod annotation is performed during backup
• Verify that a post backup hook provided via Backup spec is performed during backup

Restore Hooks

• Verify that an InitContainer restore hook provided via pod annotation is performed during restore
• Verify that an InitContainer restore hook provided via Restore spec is performed during restore
• Verify that an InitContainer restore hook provided via Restore spec is performed during restore that includes restoring restic volumes
• Verify that an Exec restore hook provided via pod annotation is performed during restore
• Verify that an Exec restore hook provided via Restore spec is performed during restore

Resource filtering

• Verify that backups and restores correctly apply the following resource filters:
  • --include-namespaces
  • --include-resources
  • --include-cluster-resources
  • --exclude-namespaces
  • --exclude-resources
  • velero.io/exclude-from-backup=true label
