There is a more complete listing of testing methodologies the Java SE 
team uses here:

       http://openjdk.java.net/groups/quality/methodologies.html

The SQE team (which I represent) is still in the planning for what tests 
we're going to release.  One thing we want to do is work together with 
the public to build new tests because I think there's a lot of 
information held in the minds of application developers about the real 
quality issues y'all are facing, that information is not known to us, so 
it would be most productive to work together to turn that information 
into tests.
