Hello everyone, I just wanted to know if pants supports merging xunit reports?

It does not. I think the only real reason is ignorance of a tool that can do this. For coverage we merge, but that's because coverage includes a merge tool (

coverage combine

). See here for the overview of that handling: https://github.com/pantsbuild/pants/blob/eeb3fd97710c9f37fd7344ee584f263065ac33e7/src/python/pants/backend/python/goals/coverage_py.py#L68-L86

I've found this project: https://github.com/weiwei/junitparser#merge-xml-files

Great!

Fwiw I was using this tool in CI for a few months now as a cli command, and it works
