Updated Presentation - Using Formal Specification Models and

Many people depend on web applications for important daily activities. But web application quality has not kept pace with popularity. Hence, improved web application quality is needed and increased testing can help. One step in this direction involves creating schemes to support automatic generation of navigation test cases. Approaches involving formal models, Unified Modeling Language development models and other mechanisms have been tried. But they are always used in isolation. Consequently, a combination of formal specification models and UML models for the generation of test cases is proposed. To evaluate the effectiveness of this approach a case study is used. Combined model based test cases are compared to captured user sessions of volunteers. Since test cases and user sessions are just sequences of logical web pages, Levenshtein distance is used for comparison purposes. Preliminary empirical results show there is value to the approach in that the combined test set does a better job of mimicking real user sessions than does test cases from UML models alone. There are a few advantages to the approach. It is easy to create the models and subsequent test case generation can be completely automated. With the approach, test cases are available very early in the development process when it is more economical to repair the problems they identify. Contributions made from the study involve the proposal of an innovative model combination, evidence to support its merit and the identification of implementation hurdles.
