Thorough and effective testing is necessary to produce high quality and reliable software. The primary goal of testing is to cover as many as faults in the software. Test case design is an essential task in the testing activities of software development. Further, manual testing is time-consuming and labor-intensive for large software. Automated design of test cases is very important activity in software testing process. In this paper, the UML activity diagram is used for automatic test case design. Using the UML activity diagram, we present a test case generation methodology. First, a specific activity diagram is to be converted to a graph, called ACtivity Transition Graph (ACTG) is constructed from. Then by traversing the ACTG and using different coverage criteria, the test paths are generated. Finally, test cases are generated using our proposed Generation of Test Cases from the Activity Diagram (GTCAD) algorithm from the test paths. The approach presented in this paper shows all activity flows during testing of object-oriented software and finds all activity related faults as well as hybrid coverage based synchronous faults.
