Improving dependability of software components by using wrappers

Authors

Abstract

Protective wrappers are used to make components behave in a robust way. They are particularly useful when the robustness of the reused component is not guaranteed. How to be sure that the wrapped component meets the system requirements? How to assure that the wrapper really protects the system against component failures? This paper presents the use of system-level fault injection to answer these questions. We also present a case study to illustrate the proposed methodology as well as the experimental results obtained.
