* use tests instead of filters
* Don't check 'rc', use success/failed tests
- yum module use 'fail_json' which set 'failed'
- 'rc' is for backward compatibility:
bbd6b8bb42/lib/ansible/executor/task_executor.py (L571)
- besides yum module doesn't document any return values
* Allow to run tests twice in a row
ansible-test is executed with '--retry-on-error' switch, then tests must
be able to executed twice in a row.
