Testing Environment for CPS by Cooperating Model Checking with Execution Testing

Abstract

In this study, we propose a testing environment for cyber-physical systems (CPS). In system testing for CPS, many tests are difficult to design or implement because of these systems’ many product variations. The proposed environment executes the tests and guarantees that these systems operate reliably using two methods. The first method provides easy management of test cases by managing functions to be tested and configurations to be tested separately. The second method involves automatic testing of real devices based on model checking technologies. The authors have developed a horizontal prototype of the proposed environment and confirmed its feasibility and applicability.
