In this paper we consider the problem of automatically generating test suites associated with web-based enterprise systems. In particular, we discuss the construction of a tool deployed as a plugin for the popular open source Integrated Development Environment (IDE) Eclipse. Our tool allows developers to automatically generate and reuse test classes, test data, as well as manually define test data. Once these components are in place, developers can launch so-called “in-container” test suites, and gather information about the results by using the also popular (and open source) JUnit framework. All features are provided to the developer through a wizard-like graphical user interface embedded in the IDE. Our tool is available from sourceforge.net under “strutstest”.
