Unlike the typical graphical applications, Emacs's UIs are mostly
controlled by events that have a very shallow translation to Lisp
data.  Even mouse clicks can be faked, and a convenient Lisp function
to make that totally easy would not be hard to write.

Perhaps the input side of testing UI features will be fairly easy.

The output side is not so straightforward, but if we set up something
to accumulate a sort of dribble record of X11 output operations, in
the form of Lisp-visible data, maybe tests could check that to see
if they have changed from before.
