With some help of Christian I have been writing some test cases using 
ert.el. I have found ert.el easy to use.

I know that Christian and Phil wants to improve it more. (And I have 
some suggestions based on the few tests I have written so far.) I think 
that here is a good chance to get a unit test framework into Emacs.

Most of the few tests so far are for nXhtml, but I just wrote a test for 
how scrolling is done when `scroll-conservatively' is 1. I wondered if 
it was possible to test this. It seems so.

(The result of this test actually shows that Emacs sometimes scrolls 
more than 1 line when calling next-line repeatedly. Is this expected or 
is it a bug?)

If someone is interested in looking at this it is currently all in 
nXhtml package (otherwise I would not have time to test). The test above 
is in the latest beta which is here:

   http://ourcomments.org/Emacs/DL/elisp/nxhtml/beta/

Maybe this can be used when reporting bugs? Either the reporter or 
someone who tries to fix it could write a test for the bug.
