To reduce this effort, we have developed a widely automated method for deriving test plans from requirements that are expressed in natural language. It consists of three stages: annotation, clustering, and test plan specification. The general idea is to exploit redundancies and implicit relationships in requirements specifications. Multi-viewpoint techniques based on RM-ODP (Reference Model for Open Distributed Processing) are employed for specifying the requirements. We then use linguistic analysis techniques, requirements clustering algorithms, and pattern-based requirements collection to reduce the total effort of testing against the requirements specification. In particular, we use linguistic analysis for extracting and annotating the actor, process and object of a requirements statement. During clustering, a similarity function is computed as a measure for the overlap of requirements. In the test plan specification stage, our approach provides capabilities for semi-automatically deriving test plans and acceptance criteria from the clustered informal textual requirements. Two patterns are applied to compute a suitable order of test activities. The generated test plans consist of a sequence of test steps and asserts that are executed or checked in the given order. We also present the supporting prototype tool TORC, which is available open source. For the evaluation of the approach, we have conducted a case study in the field of acceptance testing of a national electronic identification system. In summary, we report on lessons learned how linguistic analysis and clustering techniques can help testers in understanding the relations between requirements and for improving test planning.}}, author = {{Güldali, Baris and Funke, Holger and Sauer, Stefan and Engels, Gregor}}, issn = {{0963-9314}}, journal = {{Software Quality Journal}}, number = {{4}}, pages = {{771--799}}, publisher = {{Springer Nature}}, title = {{{TORC: test plan optimization by requirements clustering}}}, doi = {{10.1007/s11219-011-9149-4}}, volume = {{19}}, year = {{2011}}, } @proceedings{7774, editor = {{Van den Bergh, Jan and Sauer, Stefan and Breiner, Kai and Hußmann, Heinrich and Meixner, Gerrit and Pleuß, Andreas}}, title = {{{Proceedings of the 5th International Workshop on Model Driven Development of Advanced User Interfaces (MDDAUI 2010): Bridging between User Experience and UI Engineering}}}, volume = {{617}}, year = {{2010}}, } @inproceedings{8027, author = {{Gimnich, Rainer and Kaiser, Uwe and Momm, Christof and Quante, Jochen and Riediger, Volker and Sauer, Stefan and Trifu, Mircea and Winter, Andreas}}, editor = {{Doberkat, Ernst-Erich and Kelter, Uwe}}, number = {{2}}, pages = {{28--85}}, title = {{{Proceedings 12.

In GSD, such a diversity can lead to new problems: offshore development teams have to repeatedly re-adjust to method variants used by the respective business units. This can lead to misinterpretation of information and risks for project success. We report on re-aligning the varying software engineering methods and unifying the methodology throughout Capgemini sd&m.
