Join us for XP Utah tomorrow night at Border's. We'll be doing unit testing tools "show and tell" - Show us a unit testing tool that you're using or are interested in.
Zhon and I will show SchemeUnit, and some of the new features in JUnit 4.
For Scheme, I'm using DrScheme available at http://www.drscheme.org/. It has the unit testing tool built in.
JUnit 4.1 is available at http://junit.org.
http://xprogramming.com/software.htm has a list of unit testing tools.
