Yes, because unfortunately at this time, Tempest does not have a Python 
lib that can be import'd and used easily by other projects. We really 
should have such a thing, to make adding functional integration tests to 
non-integrated projects like Solum easier.

I think the approach you've taken in the above review is the appropriate 
one at this time. It will make eventual inclusion into tempest when/if 
Solum is integrated quite easy.
