Thank you very much for making this awesome utility that I use almost every day.
I'd like to package it for Alpine Linux (see here):
https://gitlab.alpinelinux.org/alpine/aports/-/merge_requests/20565

However, I need to run the tests on a server (no GUI).
I've tried doing them with xvfb-run python3 setup.py test, without luck.
So, do you have any way to run these tests on a server environment?

Thank you very much in advance.
