What is Software Robustness | IGI Global - The first knowledge sharing application in Vietnam

A software is robust, if any exception raised during its execution, in any architecture and with any initial state, is caught by some exception handler.

Abstract

This chapter investigates a formal approach to the verification of non-functional software requirements that are crucial in Service-oriented Systems, like portability, time and space efficiency, and dependability/robustness. The key-idea is the notion of observable, i.e., an abstraction of the concrete semantics when focusing on a behavioral property of interest. By applying an abstract interpretation-based static analysis of the source program, and by a suitable choice of abstract domains, it is possible to design formal and effective tools for non-functional requirements validation.
