MoMuT is a model-based testing tool addressing functional and non-functional test-case generation from behaviour models. It can work from several different input modelling languages (e.g. UML and domain specific languages). ([1][2][3][4]).
Detailed Description
MoMuT is a model-based testing tool addressing functional and non-functional test-case generation from behaviour models. It can work from several different input modelling languages (e.g. UML and domain specific languages).
For functional test- case generation, it uses mutation-based test- case generation, where a behaviour model is slightly changed (= mutated) and test cases are searched that would allow to discriminate the original and the mutant by the outside behaviour. The change might e.g. be a modified operator or a literal used. The concept is sketched in the following figure.
Non-functional aspects that can be addressed are:
- safety invariants (by checking condition during exploration)
- robustness (via smart fuzzing on top of generated tests)
- performance (if a learned cost predictor can be derived)
Contribution and Improvements
In the project, we will improve support for testing communication protocols driven by the needs of evaluating the correctness of an implementation of a key exchange protocol.
Interoperability with other C4D tools
Models to be used as input for MoMuT can be in different formats and formalisms e.g. UML (in Eclipse Papyrus or SparxSystems Enterprise Architect format), a MoMuT specific textual format or a domain specific language. If Papyrus UML is used, this should be compatible/integrable with models for Papyrus4Robotics. This could also lead to interoperation with the security analysis tool.
