@asedeno this is great! I can see that https://github.com/asedeno/whoosh/actions/runs/943788205 runs clean.

@mchaput this looks like a quick win to merge and have automatic feedback on testsuite runs on multiple python versions.

[asedeno]

If this gets merged, it should be followed up with an update to the python versions it tests with. I'd recommend removing 3.5 and 3.6, and adding 3.10 and 3.11.

Looks pretty good, it is only a bit behind meanwhile because this is rotting here since quite a while, so a few minor updates could be done before merging this.

Don't understand why this is not yet merged.
Having CI feedback for all supported python versions is pretty essential for a project.

Can we add 3.10 and 3.11 here?

Suggested change

	python-version: [2.7, 3.5, 3.6, 3.7, 3.8, 3.9]
	python-version: [3.8, 3.9, "3.10", 3.11, 3.12]

[ThomasWaldmann]

should be updated to:

actions/checkout@v3
actions/setup-python@v4

Suggested change

	- uses: actions/checkout@v2
	- name: Set up Python ${{ matrix.python-version }}
	uses: actions/setup-python@v2
	- uses: actions/checkout@v4
	- name: Set up Python ${{ matrix.python-version }}
	uses: actions/setup-python@v5

[ThomasWaldmann]

Hmm, this is different from what tox.ini is using. Which way is better?

Suggested change

	pip install pytest nose coverage cached-property
	python setup.py clean build install
	- name: Run test
	run: nosetests --with-coverage
	pip install pytest pytest-cov coverage cached-property
	python setup.py clean build install
	- name: Run test
	run: pytest

nose stopped working around Python 3.8.
