Abstract—Graphical User Interface (GUI) is pervasive to the extent that half of the code of the software systems written today is to produce the required GUIs. Test case generation for GUI based software systems is complex as it is necessary to include all possible sequences of events that may be exercised by the widget or end-user. The major issue with GUI based systems is that even a single change in the GUI may make the entire suite of existing test cases unusable. Hence a solution to analyze the existing test cases (i.e. the test cases that were already generated before modification of GUI) and identify the test cases that have become unusable and that are reusable in the context of the modified GUI is provided here. Test cases that are reusable are retained and the test cases that have become unusable are subjected to transformations. These transformations make the unusable test cases reusable through the construction of Event Flow Graph (EFG) generated and parsing EFG using Depth First Search (DFS) to identify reusable and unusable test cases.

Index Terms—Graphical User Interface, Test Case Generation, Event Flow Graph, Depth First Search, Unusable Test Cases, Reusable Test Cases.
