which scheduler is selected?

[choppsv1]

During setup (deep inside a call chain, far from the actual module setup function) I need to create a log/tmp directory path for the tests that will be running. I want this to work for --dist=loadfile as well as --dist=each. For the each case I will add the worker as a sub-directory so each run does not conflict; however, for the loadfile case (which most people will use) I do not want to do that, as the added "gw0", "gw1", ... directory just obfuscates things.

So, what I need to do is a way to determine which type of scheduler is being run (or some indication that multiple of each test can be running at the same time). How could I do this? I do have a pytest_configure() in my conftest.py if that might be one place to check?

One solution would be to look at the option itself:

import os
def pytest_configure(config):
    if "PYTEST_XDIST_WORKER" in os.environ:
        return
    if config.getoption("distmode") == "each":
        ...
    elif config.getoption("distmode") == "load":
        ...

Note that this will only work on the master node.

Right I needed the info in the worker (to determine how to create log direcotry). I used your exampel (changed "distmode" to "dist") and set an environment variable which did get passed to the worker.

    if "PYTEST_XDIST_WORKER" not in os.environ:
        os.environ["PYTEST_XDIST_MODE"] = config.getoption("dist", "no")

That's a good solution (also demonstrates how to pass data between main and the worker). I think you can mark your own reply as the answer to the question then. 👍

It' not offering me an option to mark as the answer oddly.
