At UCAAT 2021, learn about the "3 Things you Have Always Wanted to Know about the Test Description Language". Watch this presentation and several other talks related to TDL at the eighth ETSI User Conference of Advanced Automated Testing (UCAAT) 2021.

Join us in a virtual worldwide event, free of charge, from October 19th to October 21st. The conference also includes talks and tutorials on numerous other topics related to automated testing and has established itself as a meeting point for testing experts from industry, academia, and standardisation.

ETSI has recently published two sets of test specifications using TDL. ETSI's Technical Committee for Methods for Testing and Specification (TC MTS) has recently issued a three-part test specification for the MQTT protocol, as well as a three-part test specification for the CoAP protocol. Both are commonly used in the IoT industry. Download these test specifications, and other examples of how to use TDL, from our materials page.

We are happy to announce that the article "Using TDL for Standardised Test Purpose Definitions" (preprint by Fraunhofer) is accepted at the 13th IEEE International Workshop on System Testing and Validation (STV'20), co-located with 20th IEEE International Conference on Software Quality, Reliability, and Security (QRS 2020). Within this article, the Structured Test Objective Specification extension for TDL and its application in several contexts related to standardised test purposes are discussed.
