KubeVirt CI Prow instance relies on a home made plugin to provide a way to test changes to Prow Jobs by rehearsing them before merging the changes.

The code for this plugin is hosted in our GitHub repository: https://github.com/kubevirt/project-infra/tree/main/external-plugins/rehearse.

As with many other in-house tools, development has stalled. Some features are never implemented, and maintenance is not really provided.

We might consider using the rehearse plugin developed by OpenShift CI which provides more feature and could relieve some maintenance burden from us.

The rehearse plugin from OpenShift CI is hosted in their GitHub repository: https://github.com/openshift/ci-tools/tree/main/cmd/pj-rehearse.
