0% coverage report from codecov

[Remi-Gau]

I am getting some strange reports from codecov from the output from the moxunit-action.

My tests passes, the coverage differences show some changes, but it still tells me I am hitting 0 lines.

See here: bids-standard/bids-matlab#124 (comment)

I could take it up with codecov but I would like to make sure it does not come from moxunit action or moxunit first.

Any idea or pointer?

Hmm, I am not sure what the problem here is. The unit tests seem to run and a coverage report is uploaded.

But I noticed a warning in the codecov action:

I don't know if it is related, but have you tried checking out your repo with fetch-depth=2?

[Remi-Gau]

Good catch but no luck.

The warnig is now gone but still getting a 0% coverage... 😢

[joergbrech]

Hmm, maybe its just your one PR that is stale since some of the previous uploads to codecov didn't succeed:

• https://app.codecov.io/gh/bids-standard/bids-matlab/pulls?page=1&state=open&order=-pullid
• https://community.codecov.io/t/cant-get-codecov-to-work-with-monorepo/2462/13

So with some luck, it will work on subsequent Pull Requests.

Can you check one more thing? Could you upload the coverage.xml file as an artifact to check the coverage manually? See here for an example:

moxunit-action/.github/workflows/test.yml

Lines 67 to 83 in 6bb7222

	test-cover-xml-file:
	runs-on: ubuntu-latest
	steps:
	- name: Checkout repo
	uses: actions/checkout@v2
	- name: Run unit tests
	uses: ./
	with:
	src: tests/src
	cover_xml_file: coverage.xml
	- uses: actions/upload-artifact@v1
	with:
	name: coverage_file
	path: coverage.xml
	- uses: codecov/codecov-action@v1
	with:
	file: ./coverage.xml

If we have zero coverage in the xml-file, then this is a moxunit/moxunit-action bug. If no, than this is a codecov issue.

Somehow I am getting the same result on a PR on my own repo...

OK I added the upload artifact... But how do I then view it and where? (I am such a noob 🙈)

[joergbrech]

Yeah, it took me a while to find the artifacts as well 😝 They are hidden in the Summary of your action run: https://github.com/bids-standard/bids-matlab/actions/runs/549348089

If you open the file you see that you really have no line hits, so this is not a codecov issue. Seems like we need to dig deeper... 🤷 I will check it out

Sweet !! Thanks.

Let me know if I can help your search. One possibility: Is the potential issue related to the fact that this "package" code (folder start with "+") ?

[joergbrech]

Yes that seems to be the problem. I cloned your repo, removed the + from the directory names and generated the coverage report manually with https://github.com/MOcov/MOcov and I get a nonzero coverage. I just don't know exactly what the problem is. So maybe raise an issue at https://github.com/MOcov/MOcov?

[Remi-Gau]

You're the best !!!! Will raise an issue there!!!
