Adds coverage [extended]

• Adds coverage #316

Pull Request Overview

This PR enhances test coverage tracking by tagging coverage contexts per OS/Python version, updating dependencies and CI workflows to collect and combine coverage artifacts, and adding a coverage configuration file.

• Introduce an autouse pytest fixture to switch coverage contexts based on OS, Python version, and test name.
• Add pytest-cov to test dependencies and modify GitHub Actions to run pytest with coverage, upload per-matrix artifacts, and aggregate them in a separate job.
• Include a .coveragerc with coverage settings for sources, reports, and HTML output.

• The geekyeggo/delete-artifact action deletes remote artifacts from GitHub rather than cleaning up local files. Replace this with a local cleanup command, e.g., run: rm -rf downloaded_artifacts, to avoid impacting shared artifact storage.

      - name: Clean up temporary artifacts

tests/conftest.py:7

• [nitpick] Naming the fixture cov shadows pytest-cov's built-in fixture and may confuse readers. Consider renaming it to e.g. coverage_context.

def cov(cov, request):

tests/conftest.py:6

• The new coverage-context switching logic isn’t directly covered by any tests. Consider adding a unit test to verify that cov.switch_context is called with the expected context string.

@pytest.fixture(autouse=True)

[Copilot]

[nitpick] For improved readability and consistency with modern Python, consider using an f-string here instead of str.format().

Suggested change

	sys_context = "{}-py{}.{}".format(platform.system(), sys.version_info.major, sys.version_info.minor)
	sys_context = f"{platform.system()}-py{sys.version_info.major}.{sys.version_info.minor}"

Needs to work on 3.6! Blame @bw2 🥲

Looks good to me

@kingbuzzman @tristanlatr any reason not to merge this?

any reason not to merge this?

Yes. Because it doesn't work 🤦‍♂️🤣

While it looks amazing on paper, the context is being ignored in CI and well, it just strips it and gives you the regular "path/file.py::TestClass::test_func" -- still working on it, hence the "draft" 🤣
