• uses the test Docker Image generated by the ACR: Docker Push Test job to run tests in the Kubernetes cluster
• uses the revision number generated in the first step to downgrade the database

Troubleshooting:

• in case of a failed test, inspect the logs of this job to identify the issue and resolve it by updating the application code
• in case this workflow corrupted app.dev.kern.ai, manually run K8: Apply in k8-cluster-cognition to apply the latest container images available on dev
