I sometimes use httpunit to write regression tests. But, there must be a way to do it automatically. I'd like to use a tool where I specify a url and then enter form values and submit the form and then have it give me the httpunit code that can do what I just did over again. Then I'd just modify something in the code to test for a value on the last page and I'd be all set.
It doesn't need to use httpunit. Anything that will allow me to easily create regression tests for webapps is great.
