Test Case Generation From Behavioral UML Models

Free registration required

Executive Summary

The authors propose an integrated approach to generate test cases from UML sequence and activity diagrams. They first transform these UML diagrams into a graph. Then, they propose an algorithm to generate test scenarios from the constructed graph. Next, the necessary information for test case generation, such as method-activity sequence, associated objects, and constraint conditions are extracted from test scenario. Their approach reduces the number of test cases and still achieves adequate test coverage. They achieve message-activity path coverage and category partitioning method for each predicate conditions found in the specific path of the design model.
