A new approach for automatic generation of tests for next generation network communication services

The provisioning of value-added services in next generation networks (NGN) is a very difficult and error-prone task. Various service architectures combined with the complexity of the protocols for NGN networks poses a vast number of possibilities for mistakes during the development of new services. Therefore it is important to test services before they are deployed in a life system. For this reason, this paper proposes a Test Creation Environment (TCE), which will allow to automatically generate various test cases in the TTCN-3 (Testing and Test Control Notation Version 3) [3][4] testing language on a base of a Service Behaviour Model. Automatic provisioning is linked with a test execution framework to ensure only test certified services are deployed on the network of the service provider.
