Enhancing generated Java GUI models with valid test data

Iterative prototyping process in the development of graphical user interface (GUI) software is a considerable challenge for test automation. The maintenance work required for updating the test suites because of the constant changes in the GUI decreases the benefits gained from test automation and a large part of GUI software is still tested manually. In this paper we present a method and tool support for automatically creating and iteratively enhancing models of Java GUI applications, using the models for test case generation and automatically executing the generated test cases. During the first step the GUI Driver tool generates models presenting the state and behavior of the GUI application that is executed and observed automatically. Then the user can provide valid test data for the input fields of the GUI application and the GUI Driver tool uses the information to automatically enhance the generated GUI models. The enhanced models can be used for model-based testing (MBT) purposes.
