Synchronous testing of multimodal systems: an operational profile-based approach

In this paper we present a method for automatically testing interactive multimodal systems. The proposed approach was originally dedicated to synchronous programming which is mainly used for real-time systems. Nevertheless, the behaviour of real-time systems, consisting of cycles starting by reading an external input and ending by issuing an output, is to a certain extent similar to the one of interactive systems. So considered, this paper investigates the use of the Lutess testing environment dedicated to synchronous software for automatically testing multimodal interactive (not necessarily real-time) systems. More precisely, we focus on test data generation based on operational profiles. The main benefit of this approach is that it increases the ability to automatically test an interactive system over long input sequences, according to various use profiles
