Model-Based Web Components Testing: A Prioritization Approach

Web applications testing and verification is becoming a highly challenging task. A number of model-based approaches has been proposed to deal with such a challenge. However, there is no criteria that could be used to aid practitioners in selecting appropriate approaches suitable for their particular effort. In this paper we present a set of attributes to serve as criteria for classifying and comparing these approaches and provide such aid to practitioners. The set of attributes is also meant to guide researchers interested in proposing new model-based Web application testing and verification approaches. The paper discusses a number of representative approaches against the criteria. Analysis of the discussion highlights some open issues for future research. In response to one of the issues, we present an approach for prioritizing components for testing to maximize confidence given a limited number of test cases to be executed. Some initial results are reported in the paper.
