+
+() For domain types other than Model in Image, a verification test for JIRA OWLS-85530 is executed:
+
+   1. a static configured cluster is created using WLST in online mode.
+   2. a minor cleanup of the test environment is performed in preparation for a rerun of the
+      introspection job.  The minor cleanup function leaves the existing
+      domain-home/pv/pvc/secret/etc, deletes wl pods, deletes the introspect job, then
+      redeploys the custom overrides.
+   3. reruns the introspect job
