Testing

Scenario's

The following test scenario's must be covered by automated tests:

  • Creating 1 deployment (all modes, all environments, all storage engines)

  • Creating multiple deployments (all modes, all environments, all storage engines), controlling each individually

  • Creating deployment with/without authentication

  • Creating deployment with/without TLS

  • Updating deployment wrt:

    • Number of servers (scaling, up/down)
    • Image version (upgrading, downgrading within same minor version range (e.g. 3.2.x))
    • Immutable fields (should be reset automatically)

  • Resilience:

    • Delete individual pods
    • Delete individual PVCs
    • Delete individual Services
    • Delete Node
    • Restart Node
    • API server unavailable

  • Persistent Volumes:

    • hint: RBAC file might need to be changed
    • hint: get info via - client-go.CoreV1()
    • Number of volumes should stay in reasonable bounds
    • For some cases it might be possible to check that, the amount before and after the test stays the same
    • A Cluster start should need 6 Volumes (DBServer + Agents)
    • The release of a volume-claim should result in a release of the volume

Test environments

  • Kubernetes clusters
    • Single node
    • Multi node
    • Access control mode (RBAC, ...)
    • Persistent volumes ...
