AUTOMATED SOFTWARE TESTING SYSTEM

An automated software testing system for testing system-under-test resident software without extensive intrusion into the system-under-test hardware or software. A first version of interactive software is executed on the system-under-test. During execution all input signals to the system-under-test such as mouse activities and keystrokes are recorded by the testing system as a script. Additionally, selected system-under-test display images are captured by the testing system. Subsequently, a second version of the interactive software is executed on the system-under-test and the previously recorded script is played back. The images generated by the second version of software are compared to the images generated by the first version of software and the differences are displayed.
