+## Description
+
+This tests checks that if namespace labels used in a policy are not present the resource is NOT created.
+If the expected labels are defaulted in the policy the resource creation should work fine.
+
+## Expected Behavior
+
+The first part of the test checks that the resource fails to create if namespace labels are not present.
+Then the policy is updated to use default values when namespace labels are missing, then the resource should be created without issue.
