coverageHtml is empty

[isFakeAccount]

Hi,

Not sure what I am doing wrong or if there is a bug but the steps.coverageComment.outputs.coverageHtml seems to be empty for me.

Action result: https://github.com/isFakeAccount/psnawp/actions/runs/14426594421/job/40456327241

See Update Readme with Coverage Html

which is basically this

      - name: Update Readme with Coverage Html
        run: |
          echo "Coverage Percentage - ${{ steps.coverageComment.outputs.coverage }}"
          echo "Coverage Color - ${{ steps.coverageComment.outputs.color }}"
          echo "Coverage Html - ${{ steps.coverageComment.outputs.coverageHtml }}"

My github action: https://github.com/isFakeAccount/psnawp/blob/41fa43748c50262e29ea46b4f5f51779531f1ea2/.github/workflows/code_coverage.yaml

So I was sorta able to fix it. I switched back to pytest-coverage-path from pytest-xml-coverage-path. That fixed my issue.

I think the issue comes from this line.

  const { html } = options.covXmlFile
    ? getCoverageXmlReport(options)
    : getCoverageReport(options);

getCoverageXmlReport isn't able to generate the html report so it returns empty string. Why it isn't able to do that? idk.

from what i see, to generate pytest-xml-coverage-path you need to specify (according to docs) --cov-report "xml:coverage.xml

Not so fast. @MishaKav

I think you overlooked the fact that my coverage settings are provided in pyproject.toml

[tool.pytest.ini_options]
addopts   = "--cov=psnawp_api --cov-report html --cov-report term --cov-report xml --junitxml=pytest.xml"
testpaths = ["tests"]

and here is the proof that coverage.xml was indeed created and read by pytest-coverage.

And just to satisfy your requirement, I even added the --cov-report xml:coverage.xml as one of the arguments. As you can see it changes nothing.

Also, this https://github.com/isFakeAccount/psnawp/actions/runs/14459786399/job/40550125966

I added a step to cat the coverage.xml so you can see not only coverage.xml is generated. There are also no issues with it like empty file or something.

I just ran into this issue. My coverageHtml output is empty, but the summaryReport output contains both the HTML and then the test summary report. I see where it overwrites the summaryReport with the combination. Why does it overwrite the output again for both coverageHtml and summaryReport. There doesn't seem to be a condition or other code branch in between so it will always write the outputs and then overwrite them again later.

Same here, new coverage terminal report does not work anymore, and switch to xml report instead does not help...

Hi @MishaKav, I was getting this issue that wasn't present before. I am sure that the file is present

        uses: MishaKav/pytest-coverage-comment@main
        with:
          pytest-coverage-path: pytest-coverage.txt
          junitxml-path: report.xml

Run MishaKav/pytest-coverage-comment@main
