Specify once test everywhere: Analyzing invariants to augment service descriptions for automated test generation

Abstract

We present a technique which enables a novel specify once, test everywhere paradigm by exploiting invariants in a reference ontology. In our approach, each service operation is described in an IOPE paradigm: Input, Output, Precondition and Effect. Our approach augments the service description by creating additional service fault specifications to describe the exceptional behaviors which may arise as a result of invariant violations. We describe our invariant analysis technique and present experimental results which justifies the underlying intuition. © 2008 Springer Berlin Heidelberg.
