Description

I did a little hacking on the actions you set up:
https://github.com/ashryanbeats/xdpm/blob/github-actions/.github/workflows/cli-test.yml

Here's the result:
https://github.com/ashryanbeats/xdpm/runs/346161827

You'll note that there are no more failure annotations. This may not be the final result we're looking for, but I'm hoping this is helpful.
