Absolutely! This was my reason for pushing Hudson. In addition to making it easy to build your stuff and have it ready for deployment, it does a great job of tracking tests. (I think I've gone on about it at great length about it elsewhere...)

Key takeaways, anyway, are prove --formatter TAP::Formatter::JUnit >TEST-testname.xml and adding **/TEST-*.xml to Hudson as the files it should search for to find test results. This combination automatically captures all your test output and lets Hudson track the number of tests, whether they succeed or fail, and so on.
