[BUG] Syntax error if no files to upload found

[martincostello]

Describe the bug

If the build that is intended to produce test reports fails (so no reports are generated), the action logs a warning due a syntax error.

To Reproduce

Run a workflow containing the step below with no other content that generates test results to upload.

- name: Upload test results to Codecov
  uses: codecov/test-results-action@f2dba722c67b86c6caa034178c6e4d35335f6706 # v1.1.0
  if: ${{ !cancelled() }}
  with:
    token: ${{ secrets.CODECOV_TOKEN }}

Expected behavior

The action handles the lack of files in an appropriate manner.

Regression

Unknown.

Workflow

Hi @martincostello, thanks for linking the workflow it helped me identify the issue pretty quickly, it seems that the action is not able to detect that you're running on an ARM machine, can you modify your workflow to specify linux-arm64 as the OS name
when calling the action? like such:

uses: codecov/test-results-action@v1
with:
  ...
  os: linux-arm64

[martincostello]

I can try applying that out as a workaround tomorrow and let you know what happens.

[martincostello]

That fixed it, but the workaround is pretty ugly:

+ os: ${{ matrix.runner == 'ubuntu-24.04-arm' && 'linux-arm64' || '' }}

[joseph-sentry]

hmm, I see. There's one more alternative that I just remembered @martincostello

Can you try replacing the call to the test-results-action to a call to the codecov-action with report_type = test_results like so:

    - name: Upload test results to Codecov
      uses: codecov/codecov-action@ad3126e916f78f00edff4ed0317cf185271ccc2d # v5
      if: ${{ !cancelled() }}
      with:
        flags: ${{ matrix.os-name }}
        token: ${{ secrets.CODECOV_TOKEN }}
        report_type: "test_results"

This should allow you to avoid having to pass the OS argument manually.

[martincostello]

So this action is actually completely redundant?

[joseph-sentry]

@martincostello we originally thought they would be completely separate features, but slowly learned that they didn't require the separation. Combining the actions in on our roadmap, but not in the near future.

[martincostello]

So is the recommendation to stop using this action completely and just run the original codecov action in two different modes?

[joseph-sentry]

For your specific case, yes.
