So, we have a grails app set up with a Hudson CI build process. We're running unit tests, integration tests, and about to set up Selenium for some functional tests as well.

However, are there any good ways of fully testing a sites links to make sure nothing has broken in a release.

I know there's link checkers in general, but I'd like to have it be a part of the build process, so a build outright fails if something isn't right.
