Hello Guix! One of the lessons from the 1.0.0 screw-up was that we should test the graphical installer itself:
https://guix.gnu.org/blog/2019/gnu-guix-1.0.1-released/ I think we should try to do that before the next release; not doing it means testing by hand, which also takes a lot of time. One idea that I had was that we could change the installer so that it listens for connections on some pre-defined Unix-domain socket. When it gets a connection, it would perform a dialog with its client: sent it a summary of the current form, wait for its choice, and so on. The forms would thus be unavailable from the keyboard: essentially ‘run-form’ calls would be replaced by ‘draw-form’ calls in that mode. Our test infrastructure would thus connect (from a marionette) to the installer and participate in that dialog. It could even take a QEMU screenshot at each step. How does that sound? Am I overlooking things? I guess the difficulty will be to represent questions and answers. Ludo’.
