Automated Testing of Context-Aware Applications (2015)
Tönjes, Ralf ; Reetz, Eike ; Fischer, Marten ; Kümper, Daniel
he development of context-aware applications is a difficult and error-prone task. The dynamics of the environmental context combined with the complexity of the applications poses a vast number of possibilities for mistakes during the creation of new applications. Therefore it is important to test applications before they are deployed in a life system. For this reason, this paper proposes a testing tool, which will allow for automatic generation of various test cases from application description documents. Semantic annotations are used to create specific test data for context-aware applications. A test case reduction methodology based on test case diversity investigations ensures scalability of the proposed automated testing approach.
Knowledge-based Spatial Reasoning for IoT-Enabled Smart City Applications (2015)
Kümper, Daniel ; Fischer, Marten ; Tönjes, Ralf
For efficient analysis of large smart city data sets in (real) time a knowledge-based approach is suggested, con- straining iteratively the search space while increasing accuracy by more complex computation. Results are shown for searching the distance to the nearest object, e.g., parking space.
