The TTCN-3 User Conference (T3UC) is an annual event which brings together the TTCN-3 community. TTCN-3 was initially conceived in Europe but then managed to establish itself quickly in Asia – especially China – as the international testing standard. As the TTCN-3 community is rapidly increasing, TTCN-3 has been used in new application domains and accumulated more positive experiences which are shared between more and more TTCN-3 users. T3UC 2010 will be held in Beijing, China, 8-19 June 2010.T3UC 2010 is co-organized by the BII Group and the European Telecommunications Standards Institute (ETSI), and supported technically by Huawei. It will feature tutorials and presentations from members of the TTCN-3 user community as well as keynotes from invited speakers.Elvior is supporting this event as a platinum sponsor and exhibitor, showcasing its TTCN-3 technology offerings. Elvior’s model-based TTCN-3 testing technology includes a model based test generator MOTES that generates TTCN-3 test cases from the UML state machines and MessageMagic TTCN-3 tool for tests development and execution.
