Approach to generating functional test cases from BPMN process diagrams

Business Process Model and Notation (BPMN) is a popular and widespread modelling language used to describe business processes. These BPMN business process models can serve as a foundation for functional software testing. Functional software testing is an important part of software development, which ensures that software works as expected and that it includes all the desired functionality, as defined in the process models. This position paper presents an approach and considers two different methods on how to automatically create functional test cases from BPMN business process models. The generated test cases shall be understandable for all stakeholders and abstracting from the technical implementation. To achieve this general understandability of the test cases, Gherkin is used as a test case definition language. The two proposed methods will be developed and evaluated in future work. This planned evaluation includes comparing the automatically created test cases with manually created ones.
