parallelized tests

[keszybz]

This came up as part of the package review for Fedora [https://bugzilla.redhat.com/show_bug.cgi?id=1288870]: tests are the slowest part of build, it would be great if tests could be use a specified number of threads to run faster.

[superbobry]

This can be easily handled by using a parallel test runner: just add --processes=N when calling nosetests or set NOSE_PROCESSES environment var .

[keszybz]

I already tried that, --processes=N causes massive test failures:

$ nosetests --processes=12  -v

Ran 298 tests in 132.730s

FAILED (SKIP=8, errors=217)

Without --processes=N, tests finish successfully, albeit slowly.

[superbobry]

Interesting. I've tried running with --processes locally and got a lot of errors as well.

Another option is to use pytest with xdist to run the tests in parallel. I did some experiments and it seems pytest can handle almost all of the tests. The failing ones complain about model context not being active. I guess we'll need to look into that.

pytest would work for us (xdist is not packaged for Fedora, but this is something that we should fix anyway).

Some tests fail with:

        use 'py.test --fixtures [testpath]' for help on them.

This looks like py.test / nosetests incompatibility.

But there are also real test failures. They all seem to be related to mismatched array sizes:

Yeah, running python tests in parallel rarely works out of the box and can be a huge pain to get to work.
