This change replaces in many identity functests the pattern:
raw_resource = create_resource(...)
check(raw_resource)
self.addCleanup(delete_resource, ...)
...
by the pattern:
raw_resource = create_resource(...)
self.addCleanup(delete_resource, ...)
check(raw_resource)
...
which ensures that cleanup is defined and called after the test even if
check(resource) fails.
