ETSI’s TTCN-3 is a well established mature testing technology. During its 10+ year lifespan, the realization of its flexibility and adaptability has led to its rapid deployment in the telecommunication domain plus many other domains, including automotive, medical, aerospace, transportation, and others. In addition, its use has expanded from functional conformance testing into load, performance and interoperability testing.

Over all these years, TTCN-3 has also been constantly improved to cope with the latest upcoming testing requirements. Identifying future challenges of testing is and has always been a key concern to keep TTCN-3 as a modern and innovative testing technology and thereby protect existing investments in TTCN-3. Recent shifts in technology (For ex: Agile Development), as well as upcoming new application areas such as Long Term Evolution (LTE) and Machine-to-Machine(M2M) have a particular impact on system validation and testing. This year's conference will be followed by a separate workshop on model-based testing which was turned recently from a topic of research into an industrially deployed testing technology due. ETSI will share its ongoing standardization efforts in this area and also give an opportunity to listen and share industrial user experiences with model-based testing.
