Experience report on conformance tests for CORBA ORBs

Middleware platforms are in widespread use for distributed systems. Their quality is key to the stability and interoperabilily in multi-vendor heterogeneous environments. It is the aim of the EC IST project CORVAL2 to enhance the techniques used to validate the conformance of OMG's CORBA technology. The paper investigates testability aspects of CORBA ORBs and considers CORBA based systems both from a theoretical and practical view on testing. Test strategies are proposed and a conformance test suite presented.
