In "Thinking in Java", 3rd Edition, Bruce Eckel used his own
unit testing framework. You can look at that to aee if it works for you but I personally would rather use the full functionality of JUnit.

Ant to automate your builds and tests. Maybe it would help to read "Pragmatic Unit Testing" and "Pragmatic Project Automation"
