xdist does not report warnings

Warnings raised with request.node.warn does not show warnings. -rw does not give any warning output either.

Here is the same test run without and with xdist:

$ py.test unit_tests/

but why the issue is here, and not in pytest-xdist?

The pytest-xdist repo does not have an active issue tracker, and the pytest issue tracker has an xdist component. I have reported xdist issues here before and think it is the correct place.

xdist issues are kept here under component "xdist". Often it's not clear if something needs to be fixed on the core or xdist side.

I think the warning information from the test processes is not sent back to the master so it needs fixing on the xdist side. We probably should send over all warnings when we close each testing subsession.

ah i see
a bit confusing though

This bug is still present in the most recent release of xdist (pytest-xdist==1.15.0). We are using another plugin (pytest-warnings) to issue warnings in specific cases during our tests that this prevents us from utilizing due to our reliance on xdist.
