# This test confirms that upgrading a OpenStack Umbrella Helm release using
|
|
# --reuse-values does not result in any unexpected pods from being recreated.
|
|
# Ideally, no pods would be created if the upgrade has no configuration change.
|
|
# Unfortunately, some jobs have hooks defined such that each Helm release deletes
|
|
# and recreates jobs. These jobs are ignored in this test.
|
|
# This test aims to validate no Deployment, DaemonSet, or StatefulSet pods are
|
|
# changed by verifying the Observed Generation remains the same.
|
|
|
|
# This test case is proven by:
|
|
# 1. getting the list of DaemonSets, Deployment, StatefulSets after an installation
|
|
# 2. performing a helm upgrade with --reuse-values
|
|
# 3. getting the list of DaemonSets, Deployment, StatefulSets after the upgrade
|
|
# 4. Verifying the list is empty since no applications should have changed
