Like a reftest, i.e. comparing a screenshot to what one expects the screenshot to look like? You can probably take a screenshot of the GNOME desktop by running gnome-screenshot or by making a D-Bus call to org.gnome.Shell.Screenshot.Screenshot for a new user (so themes do not affect it) and compare what is shown in the upper left corner. It says Activities and the font and color of the top left corner will presumably change rarely. A simpler and possibly preferable solution would be checking if GNOME can successfully start an application set to autostart as per the xdg desktop specification without gnome-session crashing. I am not sure how such a test can be run without disrupting a running login session. Possibly GNOME can be launched on an X server configured to use xf86-video-dummy like I once tried on a headless server, see: https://wiki.archlinux.org/index.php/Vino#Running_on_a_headless_server I do not know if this can eventually be adapted to Wayland. Xdummy probably does not support KMS which I believe is required on Wayland. I so far have not got around to contributing code to the Guix project, so I probably will not be implementing this either... Regards, Florian
