| Summary: | The activity and state chart diagrams are the most frequently used UML diagrams for testing a system based on its specification. One of the key important qualities of the UML diagrams is their comprehensibility. The content analysis of previous studies highlighted the lack of experts’ evaluation of the comprehensibility of activity and state chart diagrams with regard to test case generation. Thus, the main objective of this study is to evaluate the comprehensibility of the UML activity and state chart diagrams for test case generation. First, a content analysis was performed to identify the comprehensibility criteria. The criteria are perceived difficulty and subjective confidence. Next, a set of evaluation questions was designed based on the content analysis. Then, test cases were generated from activity and state chart diagrams manually of an adapted case study. An interview was conducted with five experts to validate the evaluation questions. The experts evaluated the comprehensibility of the activity and state chart diagrams by using the evaluation questions. The result of the study provided specific details of the different characteristics of activity and state chart diagrams. Further, it suggested that the activity diagram is more comprehensible than the state chart diagram in the aspect of test case generation. The finding of this study could assist software testers in choosing the appropriate UML diagrams for software testing. |
