Summary

This PR fixes the currently broken automated codecov coverage in github workflow.

Issue : #1284

Problem Reference - #1652 (comment)

Additional Technical Details Required

As mentioned here - #1586 (comment)

Additionally, the coverage report for each plugin is getting overwritten to the same XML file. There needs to be separate XML files generated for each plugin.
Lovekesh has some additional thoughts.

Currently the xml file name is being generated like coverage-multisite-${{ github.sha }}.xml, so if it's getting overwritten for each plugin, what different identifier can we use here so that it's unique for each plugin ?

The test is still failing, even after adding an additional arg seperator --, I ran a ls -la command to debug, the coverage file is not getting stored at root of the project.
Is that the cause or any other.

I'm not able to debug and stuck here, any help or insights would be instrumental.

I see this https://github.com/WordPress/performance/actions/runs/11825633049/job/32949852740?pr=1653#step:12:49 which seems to be the problem:

warning - 2024-11-13 20:58:58,206 -- Some files were not found --- {"not_found_files": ["coverage-6c3bb1148143cc38a09cb04f2cf7400b806d21c2.xml"]}

Yes, there's no coverage file to upload and hence the test is failing, however the WorkFlow before uploading is running (where xml file is generated ) and the hash is also same I verified.
So is there a way to determine that if the file is properly getting generated or not or is this some directory path issue.
Maybe file is getting stored somewhere else, and I'm trying to upload the file from root of the project.

I believe @thelovekesh has in mind what is wrong there.
