When I did pytest -v ./test again, all tests worked.
Not sure what happened, but I thought I would signal it, in case it happens again.

The problem was with random generation, some times no numbers was >= 0.4. I changed 0.4 to 0.2 to reduce the chance to have an error... And the test rerun when failed (up to 10 times).
