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.

The goal of this Open Session is to have an open discussion with TTCN-3 users, tool provider and standardization experts to discuss the Guide for the Migration to TTCN-3 V5. The document is available via https://www.etsi.org/deliver/etsi_tr/104000_104099/104081/05.01.01_60/tr_104081v050101p.pdf. This event is the 8th Open Session after previous events in January 2024, September 2024, January 2025, May 2025, October 2025, February 2026 and June 2026.

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 <to be provided>. If you have any problems or suggestions, please do not hesitate to contact the TTF T056 project manager Jens Grabowski (This email address is being protected from spambots.
