New technologies embrace TTCN-3

ETSI Headquarters, Sophia Antipolis, France – 9 June 2009

Presentations at the latest ETSI TTCN-3 User Conference have demonstrated that the internationally standardized testing language TTCN-3 has gained further ground world-wide in the domains of telecommunication, automotive and medical business.

The products of all of these sectors are becoming more and more complex, relying on extensive interactions between components and systems, and also increasingly using (and re-using) elements from third-party suppliers. This vast complexity demands extensive and thorough testing, and TTCN-3 has proved itself as an ideal and intuitive tool for defining the tests. 

The conference also confirmed that TTCN-3 has established itself as the test automation language of choice for model-based testing and automated interoperability testing. Independence from specific test tools continues to make TTCN-3 a key differentiator from other testing technologies.

This year's TTCN-3 User Conference, which took place at ETSI on 4 and 5 June, is the sixth such event and attracted 75 specialists from throughout the world. Speakers came from France, Germany, Spain, Estonia, Russia, China and Canada, with Pavel Yakovenko of the Russian Academy of Sciences and Miguel Ramos of Métodos y Tecnología, Spain, receiving best paper awards.

This geographical mix confirms the growing global interest in the language. Whilst traditional use of TTCN-3 has largely centred on Europe, other parts of the world (notably China and India) are adopting it and are developing considerable expertise in its use. In May 2009, the TTCN-3 Asia Forum was created, based in Beijing, with the purpose of facilitating and promoting the use of the language in Asia, and providing feedback into its ongoing development.

As in Europe, TTCN-3 user conferences are proving popular in Asia, reflecting the growing interest and numbers of users in the region. The next event is scheduled to take place in Bangalore, India, from 17 to 19 November 2009.

In parallel with the conference, an examination was conducted for engineers wishing to become certified TTCN-3 programmers. Also running in parallel was an ETSI Plugtests™ interoperability testing event which successfully demonstrated 100% interworking between commercial TTCN-3 tools, adding further confidence for users of this language.

About TTCN-3
TTCN-3 is an internationally standardized testing language, formally known as Testing and Test Control Notation Version 3.  TTCN-3 is different from conventional programming or scripting languages as it has been specifically designed for testing. The language is not restricted to conformance testing and can be used for many other kinds of testing including interoperability, robustness, regression, system and integration testing. Off-the-shelf tools and test systems based on the language are readily available from a variety of vendors.
TTCN-3 is a product of ETSI's Technical Committee MTS (Methods for Testing and Specification) and is constantly developed and maintained at ETSI by a team of leading testing experts from industry, research institutes, and academia.
