Yes, but it's not enough. We have discussed and created a wiki page[1] 
about how
to configuration and group harmony tests. The page is a little old, but 
I think the problems
it tried to resolve still exist now. The partitions are not only include 
'api' and 'impl', but also
include partition of different os, architecture, partition of broken 
tests and level of tests.
folder structure or exclude files can't help in this complex situation, 
so we need some tools
to help us to deal with this, i think TestNG is suitable. If JUnit 4.4 
can do it, i will vote to JUnit,
update to a new version is always easier than switch to a new tool after
