Abstract. So far, model-based testing approaches have mostly been used in testing through various kinds of APIs. In practice, however, testing through a GUI is another equally important application area, which introduces new challenges. In this paper, we introduce a new methodology for model-based GUI testing. This includes using Labeled Transition Systems (LTSs) in conjunction with action word and keyword techniques for test modeling. We have also conducted an industrial case study where we tested a mobile device and were able to find previously unreported defects. The test environment included a standard MS Windows GUI testing tool as well as components implementing our approach. Assessment of the results from an industrial point of view suggests directions for future development.

Abstract. We address the problem of misalignment of artifacts developed in agile software development projects and those required by model-based test generation tools. Our solution is domain specific and relies on the existence of domain experts to design the test models. The testers interface the test generation systems with use cases that are converted into sequences of so called action words corresponding to user events at a high level of abstraction. To support this scheme, we introduce a coverage language and an algorithm for automatic test generation.

Abstract.Model-based testing (MBT) seems to be technically superior to conventional test automation. However, MBT features some difficulties that can hamper its deployment in industrial contexts. We are developing a domain-specific MBT solution for graphical user interface (GUI) testing of Symbian S60 smartphone applications. We believe that such a tailor-made solution can be easier to deploy than ones that are more generic. In this paper, we present a service concept and an associated web interface that hide the inherent complexity of the test generation algorithms and large test models. The interface enables an easy-to-use MBT service based on the well-known keyword concept. With this solution, a better separation of concerns can be obtained between the test modeling tasks that often require special expertise, and test execution that can be performed by testers. We believe that this can significantly speed up the industrial transfer of model-based testing technologies, at least in this context.
