An enhanced technique for generating hybrid coverage test cases using activity diagrams

The complexity of software projects is increasing rapidly and in turn both cost and time of the testing process have become a major proportion of the software development process. Thus, it has become a strong motivation to investigate model based testing methods to decrease the overall cost, effort and time of the testing process by automating the generation of the test cases as well as their execution. This paper proposes an enhanced approach for automatically generating test cases from activity diagrams. Category partition method is applied to generate the final set of reduced test cases. The proposed model validates the generated test paths during the generation process to ensure that they meet a hybrid coverage criterion. The proposed model is automated and applied to around forty different case studies in different domains. Experimental evaluation is demonstrated to prove that the proposed model saves time and cost, thus increases the performance of the testing process.
