can't run cinder unit tests in parallel reliable

[Michael Kerrin]

Running cinder unit tests in parallel can reduce the time taken to do a full run from 2m 42 sec to 35 seconds approximately on my workstation. This is a big enough gain to get this to work reliable.

The issue is that we have lots a unit tests that fail when we try to run in parallel. There is no one reason, some use global variables that get modified by other tests, others return different ordering when run in parallel, etc. I am planing on uploaded a number of patches to resolve this.

Does this fix all parallel errors for you??

I still get some errors: https://gist.github.com/sombrafam/5b831e66aa26e4513c1b

Looks like there are issues with the mocks, and unfortunately we're out of time and no one is around who works on the patch. Moving to l-1.

I think this is resolved. We've had quite a few patches go in as well as a move to ostestr running parallel by default including gate for a couple months now.
