For this specific problem I was just using tests based on the things
you mentioned. For wider-ranging tests, try the CORBA Open Source
Testing project. It contains our omniORB testuite and lots of other
things. The ORBacus tests work well with omniORB and test a wide range
of things. COST lives at

Unfortunately, it seems to be dead at the moment, but with any luck it
will be back again soon.

Cheers,

Duncan.
