Trade-Off Analysis for Selective versus Brute-Force Regression Testing in FSMWeb

This paper provides a tradeoff framework to determine whether selective regression testing or brute force regression testing is preferable. The framework is based on classifying tests as reusable, retest able, and obsolete. It uses the FSMWeb model as the behavioral model upon which test generation is based. To illustrate how our tradeoff framework works for evaluating and choosing regression testing approaches for FSMWeb models, we use an example that has different modification scenarios in the FSMWeb model and analyze cost-benefit tradeoffs for the techniques that vary with the amount of changes and the impact of model changes. Further, we discuss practical issues to be considered when we choose regression testing techniques so that the employed technique meets the organization´s business values.
