Seems a little weird to run all Python unit tests in a single step. It makes
sense to group some together but I think at some point it will be weird to just
have this as one step.

That's reasonable. How would you suggest grouping them?

This is a discussion that we may also want to have w.r.t. the java unit tests,
which are currently also set to run monolithically.

Not sure exactly what tests we have but something like:
- device-related unit tests
- test runner unit tests
- ...
Or maybe have one for core pylib and others for non-pylib? Not sure what makes
sense?
