In software engineering, graphical user interface testing is the process of testing a product's graphical user interface to ensure that it meets the written specifications. This is normally done through the use of a variety of test cases. To generate a set of test cases, test designers attempt to cover all the functionality of the system and fully exercise the GUI itself. The difficulty in accomplishing this task is twofold: to deal with domain size and with sequences. In addition, the test faces are more difficult in case of regression testing. In this work, we develop a new paradigm for GUI testing, one that we call Observe-Model-Exercise (OME) to tackle the challenges of testing context-sensitive GUIs with undetermined input spaces. Starting with an incomplete model of the GUI’s input space, a set of coverage elements to test, and test cases, OME iteratively observes the existence of new events during execution of the test cases, expands the model of the GUI’s input space, computes new coverage elements, and obtains new test cases to exercise the new elements. The experimental results proves that the proposed work is better than the previously existing works.
