Errors under pytest 8.0.0: A) The (fspath: py.path.local) argument to JupyterNbCollector is deprecated. B) PermissionError: [Errno 13] Permission denied

Dear Chris,

when updating to pytest 8.0.0, released two days ago, through a corresponding PR submitted by Dependabot, ...

• https://github.com/pyveci/pueblo/pull/63

.... CI fails like:

ERROR tests/testdata/folder - pytest.PytestRemovedIn8Warning: The (fspath: py.path.local) argument to JupyterNbCollector is deprecated. Please use the (path: pathlib.Path) argument instead.
See https://docs.pytest.org/en/latest/deprecations.html#fspath-argument-for-node-constructors-replaced-with-pathlib-path
ERROR tests/testdata/snippet - pytest.PytestRemovedIn8Warning: The (fspath: py.path.local) argument to JupyterNbCollector is deprecated. Please use the (path: pathlib.Path) argument instead.
See https://docs.pytest.org/en/latest/deprecations.html#fspath-argument-for-node-constructors-replaced-with-pathlib-path

-- https://github.com/pyveci/pueblo/actions/runs/7701648260/job/20988180571?pr=63#step:5:154

This documentation probably has corresponding guidelines.

With kind regards, Andreas.

While the previous report was coming from a downstream project, when switching to this one, the issue can be reproduced like that:

pytest -vvv tests/test_plugin_collector.py

The outcome is:

FAILED tests/test_plugin_collector.py::test_collection - Failed: nomatch: '*<JupyterNbCollector*test_nb.ipynb>*'
FAILED tests/test_plugin_collector.py::test_setup_with_skip_meta - Failed: nomatch: '*test_nb.ipynb*s*'
FAILED tests/test_plugin_collector.py::test_run_fail - Failed: nomatch: '*::nbregression(test_nb) FAILED*'
FAILED tests/test_plugin_collector.py::test_run_pass_with_meta - Failed: nomatch: '*::nbregression(test_nb) PASSED*'

GH-74 partly fixes the problem, i.e. both tests test_collection and test_setup_with_skip_meta. The other two test cases wierdly error out like that, and I can't discover anything how to fix this.

I think both of those make some progress in this area. Do you think you can do anything about it, @chrisjsewell?
