execnet.gateway_base.DumpError: can't serialize <enum 'SortBy'> with pytest==9.0.0 and while using pytest-xdist #1273
Description
Since the release of pytest==9.0.0 we have started seeing failures on our CI test workflow. Our test workflow runs on a matrix of [py310, py313] and the major platforms [macos-15-intel, macos-14, ubuntu-latest, windows-latest] -- all are failing in the same way.
Failing example CI run: https://github.com/gumyr/build123d/actions/runs/19248200580

unittest.main()Failing test command:
python -m pytest -n 6 --benchmark-disable test_reproducer.py
Failing test output:
FAILED test_reproducer.py::TestShapeList::test_sort_by_type - execnet.gateway_base.DumpError: can't serialize <enum 'SortBy'>
When not using the -n option, this works fine:
python -m pytest --benchmark-disable test_reproducer.py
When using pytest==8.4.2 these BOTH pass:
python -m pytest -n 6 --benchmark-disable test_reproducer.py
python -m pytest --benchmark-disable test_reproducer.py
I strongly suspect this is related to the changes for subtests documented in the pytest==9.0.0 release notes, but I have not investigated further.
