This is a bug in 1.3 -- there was a change to the mp plugin that had an undesired side-effect. I'd suggest sticking with 1.1 for now if you need mp+generators.

Given the following:

def test_all():

I would expect the five tests to get run in parallel running with nosetests --processes=8 and thus run in approximately one second — however, it takes just over five seconds to run: they appear to be running sequentially and not concurrently.

According to the nose documentation, the multiprocess plugin has supported test generators (as the nose documentation calls them) since 1.1: I'm using nose 1.3.0 so it should be supported. Adding _multiprocess_can_split_ = True does make any difference, as one would expect, as fixtures are not used.

How do I get these five tests to run concurrently?


Thanks,

Geoffrey.

Hi, 

Is it going to be fixed soon, or is a general advise still would be 'switch to 1.1'?
