I\'d like to have it yell hooray whenever an assert statement succeeds, or at the very least have it display the number of successful assert statements that were encountered
I don't think, it's the goal of JUnit to count matched assertions or print out more verbose information. If tests are atomic, you'll get most information in there. So I would review my tests.
You're also able to establish a LogFile in JUnit. It's possible, but it will decrease test execution performance...
