I think a synopsis that spills onto multiple lines is probably too long.
How about simply:

(synopsis "Automatically tile windows in i3 and Sway")

> +    (description "This script uses the i3ipc-python library to switch the layout

Maybe something like:

(description
 "This package provides a script that automatically switches the layout
of an i3 or Sway desktop based on the dimensions of the focused window.")

(By the way, that's the standard formatting for a description: the
string is on a new line.)

You can make a working X environment with "xvfb-run -- the-test-command" 
or with (IIRC) "Xvfb :1&" + (sleep 1) (preferably the former, as the 
latter is racy) -- search with "git grep -F xvfb-run" or "git grep -F 
Xvfb" for examples.

Thanks!

xvfb-run works well, however some "Fontconfig error: No writable cache directories"
occurs. I don't know what to do with this, do you have any ideas?

For these kind of things, creating the relevant directory and setting an 
environment variable tends to work. Maybe try (setenv "HOME" 
(getcwd)))?  However, IIUC, these fontconfig errors can usually be 
ignored (probably because it's just a cache?), likely the "Transport 
endpoint is not connected" test failure is independent.

My guess is that it tries to connect to the WM i3, but that WM is not 
running in the build environment fails.

You could give starting the WM before running the test a try, but maybe 
it's not worth the effort.

Greetings,
Maxime.

We got this working on IRC :)

Looks like the tests do a popen on i3 themselves:
