5th ETSI MTS Open Session on new TTCN-3 major release (21.10.2025)

Invitation to 5th ETSI MTS Open Session on new TTCN-3 major release (continuation)

When: 21 October 2025, 2:00 p.m. – 5:00 p.m.
Where: Federal Network Agency for Electricity, Gas, Telecommunications, Post and Railway (Bundesnetzagentur), Canisiusstraße 21, 55122 Mainz, Germany

Background:
The TTCN-3 testing language has intensively been developed by ETSI during the last 20 years. By today, TTCN-3 has become a significantly important testing technology in different domains. The last major release of the TTCN-3 standards was published in 2009 with version 4.1.1. Since then TTCN-3 was constantly maintained and further developed.

Motivation:
The TTCN-3 language specification has reached the state where modernization and refactoring are required. Currently, language maintenance has become complex, since even small corrections and extensions require changes in many different places in the TTCN-3 language specification and extension packages. Also, TTCN-3 users suffer from this kind of complexity, because specific aspects of a language feature may be spread across different sections and documents. This decrease learning, understanding and, finally, acceptance of TTCN-3.

The goal of this Open Session is to have an open discussion with TTCN-3 users, tool provider and standardization experts to discuss requirements and ideas towards a new major release of the TTCN-3 standards. In 2023/2024 the members of the ETSI TTFs for TTCN-3 maintenance have already started the analysis and collection of technical issues for this new major release. The ETSI TTF T040 (https://portal.etsi.org/xtfs/#/xTF/T040/) currently is collecting further proposals regarding a modernization and innovations of TTCN-3. This event is the 5th Open Session after previous events in January 2024, September 2024, January 2025 and May 2025.

This Open Session is open for ETSI members and non-ETSI members. It is also planned to provide the possibility of remote participation. Interested persons are asked to register on the ETSI portal at https://portal.etsi.org/Meetings.aspx#/meeting?MtgId=82982.
