OK, these are small libraries for writing tests: HttpUnit <http://httpunit.org/>: 6 of 10 packages exported
SimpleStub <http://simplestub.meterware.com/>: 1 of 4 packages exported There is also the Glassfish ORB, but since that implements a public standard, perhaps its ratio of exported to non-exported projects isn’t as relevant. I think in many cases, it is the architecture of the code that matters.
