Out of tree is probably easiest, especially if we want to share tests
across projects. Take a look at Mauve (http://sourceware.org/mauve/) it
has tens of thousands of tests for core libraries (but also for byte
code verifiers, visual tests, compiler, serialization, etc.)

The good thing about having all tests of various projects in one place
like mauve is that everybody can easily run each others unit and
regression tests. There has been a discussion on the classpath
mailinglist about importing even more tests into mauve from GNU Crypto
now that that project is going to merge with GNU classpath. There were
some suggestions for improvements in the mauve setup. You might want to
join that discussion:

And of course http://sourceware.org/ml/mauve-discuss/

Cheers,

Mark
