When I run the tests from scipy.stats.tests.test_distributions only, with the option -j 8, i.e.

python3 dev.py test -m full -j 8 -t scipy.stats.tests.test_distributions

all the workers fail with errors like Different tests were collected between gw0 and gw6.

So far, test_distributions is the only test module that I have found where this occurs. All the other test modules in scipy.stats run fine. If I don't give the option -j 8, all the tests run as expected.

Does this happen for anyone else?

I suspect this is pytest-dev/pytest-xdist#432. I can fix the problem by disallowing random data in the values given in pytest.mark.parametrize().

…test-xdist.

Don't use random parameters in `pytest.mark.parametrize()`, as it can confuse
the pytest-xdist extension; see pytest-dev/pytest-xdist#432

Closes scipygh-17468.
