I think that's realistically already the scope of the QA program, we might just need to change the governance wording. Tempest has always been intended to be run on production clouds (public or private) to ensure proper function. Many operators are doing this today as part of normal health management. And we continue to evolve it to be something which works well in that environment. All the statistics collection / analysis parts in Rally today I think are basically things that should be part of any Tempest installation / run. It's cool that Rally did a bunch of work there, but having that code outside of Tempest is sort of problematic, especially as there are huge issues with the collection of that data because of missing timing information in subunit. So realistically to get accurate results there needs to be additional events added into Tempest tests to build this correctly. If you stare at the raw results here today they have such huge accuracy problems (due to unaccounted for time in setupClass, which is a known problem) to the point of being misleading, and possibly actually harmful. These are things that are fixable, but hard to do outside of the Tempest project itself. Exporting accurate timing / stats should be a feature close to the test load, not something that's done externally with guessing and fudge factors. So every time I look at the docs in Rally - https://github.com/stackforge/rally I see largely features that should be coming out of the test runners themselves. -Sean -- Sean Dague http://dague.net
