Obviously, this would be very useful.  I've looked into it a bit when
managing zsh, but never came around to it.

Anyone looking into this should take a look at "dejagnu", to be found
at any GNU archive.  It uses "expect", which is able to test
interactive programs like zsh by running them on a pty and simulating
interactive input.
