Event Handler Tree Model for GUI Test Case Generation

More and more software applications have Graphical User Interfaces (GUIs). GUI is popular because of its intuitive and convenient way to operate software. However, for its event-driven nature, it also makes applications hard to be tested, and the generation of test cases is very time-consuming. In this paper, an Event Handler Tree (EHT) model is proposed to assist the test case generation process. The EHT is constructed by analyzing source code, and with the EHT we can automatically combine the cell events into runnable test cases. Moreover, the test cases are easy to repair when GUI is modified. Experiments and discussions show our approach is feasible and convenient for test case generation.
