The objective of the TT-Medal project was to develop the methodologies, tools and industrial experience to enable European industry to test more effectively and more efficiently. The project introduced the latest testing technology, developed by ETSI, into European industry. This new technology based on the TTCN-3 testing language provided common methods and tools to enable re-use of test-ware between different phases of a product's life cycle.

TTCN3 combines advantages of increased productivity and power together with a sufficient level of formalism and a component model that gives the possibility to obtain reuse in testing. The TTCN3 language has also influenced the upcoming UML 2.0, indeed TTCN3 can be considered the first implementation of the UML 2.0 testing profile.

The approach of this project was to apply TTCN3 into a wide range of application domains. The methodology and tools developed were expected to fit to many domains not just telecommunications. The goal was to develop testing methods and tools that cover the whole life cycle of a product starting from the initial simulations and ending up with regression testing during the maintenance phase. The methods should enable reuse of test data both between products and between different phases of the development process. The methods enable automatic generation of tests as well as automated deployment of tests. The methods and tools was evaluated in several real industrial cases in several domains.
