Techniques to generate UTP-based test cases from sequence diagrams using M2M (Model-to-Model) transformation

Abstract

In order to conduct model based testing of sequence diagrams, test cases should be automatically generated from sequence diagrams. To this end, the scenarios expressed by the sequence diagrams are identified and paths that satisfy the test coverage are extracted to generate test information. However, since sequence diagrams express loop, optional, and alternative information using combined fragments, an automatic generation of test cases from sequence diagram is complicated. To solve this problem, in this paper, a model transformation process that transforms from sequence diagrams into activity diagrams is defined, the scenarios of sequence diagrams are represented in the form of control flows by the transform process. Next, test coverage is applied to generate test cases. The process to generate test cases from sequence diagrams is shown through case studies.
