@hjpotter92 Thanks for the PR.

1. Do you have somewhere how the result of this looks like? I understand that in this PR we don't see anything in codecov.io, because it creates coverage only for the master branch. But maybe you have a result of how it works in your fork?

2. Is it possible to make it working somehow also for PRs? It'd be nice to see how a PR affects the code coverage.

You can see coverage reports for other projects:

• livepeer-com
• livepeer-in-a-box

it works with open pull requests against master branch. The default codecov token (set at organisation level) hits API limits, that's why some PRs miss report generation. I'll have a discussion w/ Eli wrt the same. The code in workflow itself doesn't need any change. You can check an example report on currently open PR here: livepeer/studio#1014
