TTCN-3 is a well established mature testing technology. During its 10 year lifespan the flexibility and adaptability of the language has led to its rapid deployment in the telecommunication domain and beyond, including transportation, internet, medical, web-based services and distributed systems. In addition, its use has expanded from functional conformance testing to include load, performance, and interoperability testing.

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 – a country with a long history and the largest TTCN-3 user community today - which offers an ideal opportunity for testing experts, tools providers, and users from the whole world to come together to meet and share experiences with each other as well as to promote and ensure the continued progress of the TTCN-3 technology.

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.
