Comment 3 for bug 913812

IMHO adding more logic either directly in test code or to runners as flags/switches/options makes test cases code unmaintainable.
I think it would be better if there was `qa-regression-testing` branch for every release.
Pros:
 * readable code
 * easier to maintain
 * faster to lunch and run
 * history separated but kept
 * easier to fix test cases
