Not sure if this is a pytest bug or pytest-forked needs to change something. The traceback mostly shows pytest code only :/

Looks like this is to blame: https://github.com/pytest-dev/pytest-forked/blob/master/testing/conftest.py

Apparently pytest-forked patches atexit, but in a way that doesn't work when trying to call a function with arguments.

Tried a quick fix:

but I can't seem to successfully run the tests locally, so it'd be good if someone else could pick this up.

If anybody sends this as a PR, we'll see if it explodes in the current CI setup...

/me needs to add a toxenv hitting pytest master...

I suppose the CI setup doesn't tell the whole story as it doesn't actually test against pytest 6. I suppose having the pytest-latest environment use pip_pre = True to test against the prerelease would help?

Yeah, I guess there should be pytest-latest + pytest-stable + pytest-unstable

@hroncok

@hroncok I assume this is after my patch above? Looks like pytest-forked is using private pytest APIs which moved around with 6.0. I assume adjusting the import to do from _pytest._code import getfslineno (which should work with both pytest 5 and 6?) will help. I'm afraid I won't have the time to continue looking at this, as I've never used this plugin and should take care of some non-pytest things :)

I assume this is after my patch above?

Indeed.

@The-Compiler

I am taking @The-Compiler's work and will submit a PR. There are other failures afterwards which I'm still working on.

@bluetech

@bluetech great! Feel free to submit a draft PR so that any WIP failures are visible in the CI logs.

Released as v1.3.0: https://pypi.org/project/pytest-forked/1.3.0/ (https://travis-ci.org/github/pytest-dev/pytest-forked/jobs/712323063#L450)
