In particular, the test technology TTCN-3 (Testing and Test Control Notation) – standardized at ETSI and co-developed by Fraunhofer FOKUS – will be applied. The project is designed to help companies to improve the quality of IoT products, using test suites and test cases described in TTCN-3. This can be achieved through the exchange and use of jointly developed test suites. Developers should be given the opportunity to set up their own test environment. Through the base provided by the Eclipse Foundation, the IoT testware can be made open source and thus free of charge.
