System tests for Enterprise JavaBeans and Java based Applications with TTCN-3

Nowadays the use of complex distributed systems increases rapidly and the need for solid testing, too. Enterprise JavaBeans (EJB) is one of the most used standards for developing distributed systems. The applications based on EJB technology are secure, concurrent, transactional, etc. TTCN is in the telecommunication domain a widely established and used test technology. In its new version, TTCN-3 (Testing and Test Control Notation), it has a wider scope and applicability. It cannot be used only for testing the conformance and interoperability of communication protocols but also for testing the correct behaviour of distributed systems and application. This paper describes the language mapping from EJB/Java to TTCN-3 and an Eclipse based solution for testing EJB/Java based applications with TTCN-3.
