It depends on what you are trying to test, I suppose. I think
there is a broad class of "textual transformation" tests that
would be trivial to implement as batch jobs called from a simple
In fact, I've made a very simple sketch of how such a thing would
work, which verifies the cc-mode filling bug in CVS HEAD (and
also demonstrates that it works "as expected" for 21.1.1 and 20.7.1.)
There is a driver script which runs GNU find on a subtree looking
for programs which have the name, by convention, "run-test".
Each command "run-test" accepts an argument "--description" which
is spits out a one-line description to be displayed while the
test is running, as well as an option to specify a full path to
the emacs binary to test. Each program "run-test" returns 0 for
pass and non-zero for fail.
I suspect from perusing the mailing list that this sort of thing
might be valuable, if people would use it.
