How to set up Codecov for Github?

Question

I am getting Error: Codecov: Failed to properly upload: The process '/home/runner/work/_actions/codecov/codecov-action/v2/dist/codecov' failed with exit code 255 (https://github.com/eftalgezer/SIESTAstepper/actions/runs/3077344665/jobs/4972146066)

I have changed the Codecov version 3 to version 2, tried https://github.com/codecov/codecov-action/issues/598, Configuring codecov token in GitHub Actions .yaml for an R package, codecov fails in github actions but nothing works.

codecov.yml

python-package.yml

Edit:

I am getting Error: Codecov: Error validating uploader: Misformed armored text error in the latest version, 3.1.0. (https://github.com/eftalgezer/SIESTAstepper/actions/runs/3077489502/jobs/4972389835)

Edit:

Now I am getting the following error. (https://github.com/eftalgezer/SIESTAstepper/actions/runs/3077712442/jobs/4972763464)

Answer 1

The coverage file was not created. I have solved it with the following code.

    - name: Generate Report
      run: |
        pip install codecov
        pip install pytest-cov
        pytest --cov=./ --cov-report=xml
        codecov
    - name: Upload coverage to Codecov
      uses: codecov/[email protected]
      with:
        token: ${{ secrets.CODECOV_TOKEN }}
        directory: ./coverage/reports/
        env_vars: OS,PYTHON
        files: /home/runner/work/SIESTAstepper/SIESTAstepper/coverage.xml
        flags: tests
