Don't know, I have no knowledge about language servers. But I would
expect, that you first check whether pylsp is installed (you do it
already), and then you could connect to pylsp, send a specific request,
and decide, based on the ansewer, whether it is a proper language
server.

In this case, it is Emba indeed. We have decided to run our tests based
on Debian. I don't see a reason to change this decision.

It would be desirable to test Emacs also against other basic software
(RHEL/Fedora, *BSD, macOS, MS Windows), but this is out of our
resources.
