A Review on Test Case Generation Methods Using UML Statechart

Despite continuous effort in test case generation in UML diagrams, especially UML statecharts, there are inconsistencies in the processes used in this domain that have raised needs for a framework that will have a complete set of process to generate test cases. As a prerequisite for creating this framework and to better understand the existing processes used in test case generation, a review on existing work in this domain was conducted to discover the current methods, types of coverage criteria and types of evaluation conducted to evaluate test cases quality. The review was conducted on 24 existing work in test case generation using UML statecharts using content analysis method. The results revealed that most of the work in this domain, translated the UML statechart diagram into an intermediate model. Among the common algorithm for establishing test cases is Depth First Search. Furthermore, this review emphasizes the importance of achieving all-state coverage and all-transaction coverage in conducting coverage criteria.
