Software patterns for fault injection in CPS engineering
Nicolas Navet, Ivan Cibrario Bertolotti, Tingting Hu · 2017
Software fault injection is a powerful technique to evaluate the robustness of an application and guide in the choice of fault-tolerant mechanisms. It however requires a lot of time and know-how to be properly implemented, which severely hinders its applicability. We believe software fault injection can be made more “affordable” by automating it and have it integrated within a model-driven engineering design flow. We first propose in this paper a framework supporting these objectives. Then, illustrating on the domain-specific language CPAL, we present injection patterns that can be embedded in the application code and discuss the types of faults each supports, as well as implementation issues.
