This paper presents a new automated model-driven technique to generate test cases by using feedback from the execution of a "seed test suite" on an application under test (AUT). The test cases in the seed suite are designed to be generated automatically and executed very quickly. During their execution, feedback obtained from the AUT's run-time state is used to generate new, "improved" test cases. The new test cases subsequently become part of the seed suite. This "anytime technique" continues iteratively, generating and executing additional test cases until resources are exhausted or testing goals have been met. The feedback-based technique is demonstrated for automated testing of graphical user interfaces (GUIs). An exbstract model of the GUI is used to automatically generate the seed test suite. It is executed; during its execution, state changes in the GUI pinpoint important relationships between GUI events, which evolve the model and help to gen...
