Oomox
https://github.com/themix-project/oomox/Popular desktop application for customizing themes on Linux desktop (like WindowBlinds on Windows).
There are 6 different test environments based on Docker: https://github.com/themix-project/oomox/tree/master/dockerfiles (currently four of them are used in Travis).
It uses a lot of linters, Flake8, pylint, mypy, vulture, McCabe, ShellCheck.
One of the components uses screenshot-based UI testing (also running on Travis+Docker stack): https://github.com/themix-project/oomox-gtk-theme
Packaging for several distributions, deb packaging based on Docker so can be done from any distro: https://github.com/themix-project/oomox/tree/master/packaging/ubuntu
