Pytest order with parallel test execution

[albertino87]

Hello,
to maximize the running efficiency of the tests running in parallel it is important that the slower tests run first, and i do it by marking the tests with the decorator @pytest.mark.order(0) from the pytest-order library. however this is not respected by xdist, can you possibly fix it?

Did you check the documentation?

[albertino87]

yes I did, but that doesn't really solve the problem. I don't have a dependency problem. I don't care that all the test in one file run in the same thread. I only want that two very slow tests (in two different modules) run first. i don't see how that solves my problem
Many thanks

You can only make sure that the slow tests inside the same module run first (if you are using the --dist=loadfile option). The order in which the xdist threads is out of control of this plugin.
You may check this xdist issue and the referenced pytest-slowest-first plugin, this sounds as if it could help you.
