Comment 3 for bug 1680122

@Ghanshyam tempest test create and use random tenant/user to test by default. (use_dynamic_credentials = True ) This tenant can't list the volume which are already existed. So it passed.

here is the tempest log:

the error happened here:
https://github.com/openstack/tempest/blob/master/tempest/api/volume/test_volumes_list.py#L108

Actually I know we can pass the test by using random credentials, but our production env uses the existed credentials to test the tempest. So it happened.
