Don't show the omitted files in the Test Coverage Toolbar

[paduszyk]

I like the new Test Coverage Toolbar feature. I use it with Python and Coverage.py run via pytest and pytest-cov plugin.

Coverage.py enables omitting some files using globs (e.g. configuration modules or development scripts; see docs). I think that NOT showing those files in the toolbar could be an interesting enhancement.

Sorry if you find this issue biased to Python. I am not so familiar with other languages and testing tools available for them.

good idea yes! I can do this specifically on the python side. This will need development time so just putting it for community feedback to see how many people are hitting this issue

Thanks for the feature request! We are going to give the community 60 days from when this issue was created to provide 7 👍 upvotes on the opening comment to gauge general interest in this idea. If there's enough upvotes then we will consider this feature request in our future planning. If there's unfortunately not enough upvotes then we will close this issue.

"Run Test with Coverage" should allow omitting files from the report. Ideally, honor the "omit" setting in the coverage configuration. Some default arguments may be set, such as .venv.

It seems this can be done using a workaround, namely, by using tool.coverage.run.omit (as opposed to tool.coverage.report.omit, which I tried previously).

[tool.coverage.run]
omit = [
    ".venv/*",
    # https://github.com/nedbat/coveragepy/issues/1392
    "pyscript",
    "shibokensupport/*",
    "signature_bootstrap.py",
]

copied from #24309 as both are related to omitting files for coverage
