1) Revert direct usage of subunit Test repository should be used as launcher for tempest tests, since direct usage of `subunit` broke execution of `compute` set as well as `full` set. Tests discovery and execution can't be split at the moment. 2) Cleanup of tempest folder afterfaulty installation Also, execution of tempest sets cannot be correct without confidence in correct installation of tempest repository. Cleanup of tempest folder after faulty installation should be added to fix check of tempest installation. 3) Length of database field for verification results MutableJSONEncodedDict limited by 64k. This length is not sufficient for storage results of those verifications, which have a huge number of failures and tracebacks. 4) Incorrect usage of mock in tests Class `mock.MagicMock` doesn't have method `assert_called_once`. Instead of this one, method `assert_called_once_with` should be used. Based on the fact that this is critical error in testing, this patch affects not only tempest verification.
