JUnit can be found at http://junit.org/.

It basically provides a bunch of abstract classes that you subclass to 
test individual classes.

You write a number of test methods, mostly containing asserts -- JUnit 
provides methods like assertTrue(boolean), assertEqual(Object, Object), 
etc.

setUp() is called before each test method, and tearDown() is called 
after each one. JUnit keeps track of which tests failed and erred (an 
error occurs when an exception is thrown), and prints back a report of 
successes and failures.

When writing an API, I've found it useful to provide a complete set of 
unit tests along with the interfaces so implementers can immediately 
tell if there's an error in their code, or if there was a 
misinterpretation of the interface.

This is very simplified. I first discovered these frameworks when 
studying "agile" methodologies (like Extreme Programming). The docs at 
JUnit.org would probably help you understand much better.
