Continuing a Benchmark for UML and OCL Design and Analysis Tools [chapter]

Martin Gogolla, Jordi Cabot
2016 Lecture Notes in Computer Science  
UML and OCL are frequently employed languages in model-based engineering. OCL is supported by a variety of design and analysis tools having different scopes, aims and technological corner stones.  ...  It puts forward a set of UML and OCL models together with particular questions centered around OCL and the notions consistency, independence, consequences, and reachability.  ...  of the benchmark and improve this way it's coverage.  ...

Assembling Scenario Patterns for Checking Model Behavior

Nisha Desai, Martin Gogolla
2020 Journal of Object Technology  
We explain the catalogue applicability through a collection of exemplary models and validate our proposal through a study conducted with UML and OCL experts.  ...  For checking behavioral model properties, operation call sequences, i.e., dynamic scenarios, can be used, and developers must identify relevant scenarios.  ...  Acknowledgments Reviewers and ECMFA program chairs kept us running. They provided critical, very fruitful contributions that helped a lot to improve the work.  ...

User Assistance Characteristics of the USE Model Checking Tool

Frank Hilken, Martin Gogolla
2017 Electronic Proceedings in Theoretical Computer Science  
We demonstrate how the tool supports modelers to analyze, validate and verify UML and OCL models via the use of several graphical means that assist the modeler in interpreting and visualizing formal model  ...  Together with the Object Constraint Language (OCL), formal models can be described by defining the structure and behavior with UML and additional OCL constraints.  ...  We thank Subi Aili for his contributions to the configuration GUI -ideas and implementation -in his diploma thesis.  ...
