GUIdiff - A Regression Testing Tool for Graphical User Interfaces

Due to the rise of tablets and smart phones and their impact on everyday life, robust and high-quality Graphical User Interfaces (GUIs) are becoming more and more important. Unfortunately, testing these GUIs still remains a big challenge with the current industrial tools, which only cater to manual testing practices and provide limited oracle functionalities such as screenshot comparison. These tools often result in large amounts of manual labor and thus increase cost. We propose a new GUI regression testing tool called GUIdiff, which works similar to diff tools for text data. It executes two different versions of a System Under Test (SUT) side by side, compares the GUI states against each other and presents the list of the detected deviations to the tester. The tool is semi-automatic in the sense that it finds the differences completely automatic and that the tester labels them as faults or false positives.
