Automated Test Case Generation for Java']Java EE Based Web Applications

Automated testing is important for validating the behavior of programs with complex user interfaces, such as web applications. In the enterprise context, web applications are popular client-server programs that provide rendered web pages as a user front-end, and the business logic is typically implemented on the server-side. In this paper, we present an approach to automatically generate test cases for component-based user interfaces for web applications built on the Java EE platform. We generate a sequence of user actions to navigate through the web application. For each supported user action, we gather constraints from the view template describing the web page (e.g. a button must be enabled in order to be clicked by a user), as well as constraints that are introduced while executing a server-side component. We have implemented our approach in a tool to determine its practical use in an experiment.
