A New Approach to Design Graphically Functional Tests for Communication Services

This paper presents a new concept of how a service provider using any kind of Service Creation Environment (SCE) can verify that a generated service meets the requirements of a customer. This requires functional tests which are derived from a finite state machine-based behaviour model being composed from so-called modular finite state machines by a new composition method. The derivation of the tests is fulfilled by the usage of an adequate path finding algorithm. The following execution of the generated tests is done automatically within a Testing and Test Control Notation (TTCN-3) test framework.
