Unit tests aren't running in CI

[igoumiri]

Describe the bug

• As far as I can tell, we're only building/installing the package but we're not running the unit tests during CI.
• In addition, the CI checks on PRs appear to be blocked (waiting approval).
  
• Finally, we seems to be deploying the documentation from any branch and not just the main branch.

To Reproduce
Steps to reproduce the behavior:

1. open a PR that breaks some unit tests
2. notice that checks don't run (waiting for approval)
3. assuming checks ran and passed, notice that you're not blocked from merging
4. notice that the docs have been deployed from your branch before you even merged

I haven't actually reproduced the issue beyond step 2 but I noticed that:

1. Unit tests are broken on main
2. The CI action doesn't seem to run any of the unit tests. There is a coverage step but it's silently failing:
   

Expected behavior
All the PR checks (build/install, lint, docs, unit tests) should run on push and probably block merge until they pass.

Output
See inline screenshots.
