Environment behavior models for automation of testing and assessment of system safety

This paper presents an approach to automatic scenario generation from environment behavior models for testing of real-time reactive systems. The model of behavior is defined as a set of events (event trace) with two basic relations: precedence and inclusion. The attributed event grammar (AEG) specifies possible event traces and provides a uniform approach for automatically generating and executing test cases. The environment model includes a description of hazardous states in which the system may arrive and makes it possible to gather statistics for system safety assessment. The approach is supported by a generator that creates test cases from the AEG models. We demonstrate the approach with a case study of a software prototype of the computer-assisted resuscitation algorithm for a safety-critical casualty intravenous fluid infusion pump.
