A test framework for CORBA interoperability

This paper presents a new approach to interoperability testing of CORBA implementations. The ORB Under Test (OUT) is embedded in the test system in such a way, that the behavior of either the client side or the server side of the OUT is controllable and observable. Components of the test system emulate the peer entities of the OUT and the applications based on the OUT in order to get direct access both to the GIOP interface and to the CORBA APIs. A specification framework for the test system is proposed. It separates the concerns of test data and test behavior to facilitate modularity and dynamic of the test system. The description languages CORBA IDL, ODMG ODL and TTCN-3 are used in the framework.
