'dependency' not found in `markers` configuration option

[0-wiz-0]

Updating the pkgsrc package to 2.4.3, I noticed that the test do not run in my environment:

A similar failure occurs with 2.4.2, so it's not new breakage, but it seems it wasn't reported before.

The tests are run (using the pypi source tarball) by calling pytest.
The following Python modules are installed:

Python 3.14.6.

Doesn't #3976 fix this issue?

[0-wiz-0]

No, that commit doesn't change anything. (I applied it to 2.4.3 and tried again.)
I'm not using tox, so I'm not sure how it would.

[DimitriPapadopoulos]

I don't know either, I must admit I'm not interested in the intricacies of the Python ecosystem which has started showing its age. I would have thought that tox calls pytest, or pytest calls tox.

[DimitriPapadopoulos]

We are indeed supposed to test with pytest from command line:

codespell/Makefile

Lines 49 to 55 in 76eab06

	pytest: sort-dictionaries
	@if command -v pytest > /dev/null; then \
	pytest codespell_lib; \
	else \
	echo "Test dependencies not present, install using 'pip install -e . --group dev'"; \
	exit 1; \
	fi

or during CI:

codespell/.github/workflows/tests.yml

Lines 68 to 71 in 76eab06

	- run: make check
	if: startsWith(matrix.os, 'ubuntu')
	- run: pytest codespell_lib
	if: startsWith(matrix.os, 'windows')

And indeed it's tox calling pytest, not the other way round:

codespell/tox.ini

Lines 11 to 14 in 76eab06

	[testenv:unitest]
	description = run unit tests
	dependency_groups = dev
	commands = pytest --cov=codespell_lib codespell_lib

[DimitriPapadopoulos]

I wasn't aware of pluggy. I understand it is a dependency of pytest, but we never refer to it directly. Anyway, you do have the latest releases of both packages.

[0-wiz-0]

I found it - I was missing the pytest-dependency package.
Now I see

3 failed, 122 passed, 17 skipped

mostly because codespell is called codespell-3.14 here.

[DimitriPapadopoulos]

Thanks for the feedback. Yet pytest-dependency is part of the dev dependency group, so I would have expected pytest to install pytest-dependency automatically, somehow. However, I may be expecting too much from pytest, not to mention this could be a chicken and egg problem (pytest needs pytest-dependency to be already installed to run).

[DimitriPapadopoulos]

Alternatively remove --strict-markers:

codespell/pyproject.toml

Line 113 in 76eab06

addopts = ["--cov=codespell_lib", "-rs", "--strict-config", "--strict-markers", "--cov-report=", "--tb=short", "--junit-xml=junit-results.xml"]

I suspect this is more of a pytest issue.
