Model-Based Test Case Prioritization Using an Alternating Variable Method for Regression Testing of a UML-Based Model

Many test case prioritization (TCP) studies based on regression testing using a code-based development Stop Button approach have appeared.However, few studies on model-based mutation testing have explored what kind of fault seeding is appropriate or how much the code-based results differ.In this paper, as automatic seeding for the mutation generation, several mutation operators were employed for the UML statechart.Here, we suggest mutation testing employing the model-based development approach and a new TCP method based on an alternating variable method (AVM).We statistically compare the average percentage of the fault detection (APFD) results of the new method to other TCP methods such as a greedy algorithm for code coverage or fault exposure possibility.

Finally, in empirical studies, the model-based TCP results for a power Baggers window switch module, a body control module, and a passive entry and start system are derived; these are real industrial challenges in the automotive industry.
