There is already test framework within Guix. You may find 
information at:
https://guix.gnu.org/manual/en/guix.html#Running-the-Test-Suite

In short, there are unit tests and system tests which can be found 
at
gnu/tests/*.scm for inspiration. It is just a matter of 
time/resource
availability to write tests.

For cups specifically, you may not need screen capture processing 
or
similar. It should be enough to use CLI tools available out of the 
box.
