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.

Abstract
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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
