Generation of an automated testing environment using OCL for enterprise components

Abstract

A server-side component architecture helps us to implement an enterprise application based on the three-tier architecture. To assure its quality, a great deal of enterprise components composing it are required to test their quality adequately in time. However, previous component testing techniques did not consider an enterprise component on the three-tier architecture. Therefore, we propose an automated testing technique for an enterprise component.

We first propose a test oracle model which collects constraint information from the specification described in OCL and location information to reference behaviors of the component on the three-tier architecture. Then, we carry out a constraint-based testing using the model. We generate test drivers corresponding to test cases, execute them, and check whether constraints are satisfied or not. We have implemented our testing environment, Component Testing Manager(CTM), to support the automated process of our approach. It focused EJB component and used JPDA architecture in order to access an enterprise component and Java virtual machine.
