Graphical user interface application comparator
A graphical user interface (GUI) application comparator helps application designers create error free graphical user interface applications (GAPs). The comparator finds differences in the GUI elements used to compose an interface between a current GAP version and a subsequent GAP version. One benefit is that a test script writer may better understand how the GAP has evolved in order to write a better test script. Another benefit is that the comparator output may be analyzed by subsequent processing systems for automated analysis of test scripts.
