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.
