TY - THES A1 - Meyer, Tobias T1 - Automatisierte Tests oberflächenbezogener Geschäftslogik mit simulierten Benutzereingaben N2 - A lack of stability and reliability in user interfaces leads to user dissatisfaction. If this dissatisfaction is a repeating occurence users loose trust in the software and the company behind it. In the long run this leads to a migration from existing users to competitors and less new customers. To combat these effects companies have to ensure their user interfaces are stable and reliable. The Schleupen AG provides a browserbased user interface to its customers, which is split into a display layer running in the browser and a logic layer running on the server. In this thesis an automated solution for finding such problems in the logic layer was developed and applied to a selected subset of user interfaces. The solution was able to find multiple issues with most of them representing possible stability problems. This showed that automated testing of user interfaces for stability and reliability is possible and worthwhile.
