Test case generation for production systems with model-implemented fault injection consideration

Abstract

Complex production systems, which have to handle product diversity and short product life cycles, can only be stable and efficient when successfully tested prior to their start-up. Also, changes in automation software within the life cycle of a production system should be verified through repetitive testing before applying the new software version. Therefore, test automation in combination with fault injection on a virtual model of the production system is seen as the next step to improve the verification and validation of a production system. This work presents an approach to achieve negative test cases for a test automation framework.
