Approach to activity diagram model driven testing for Web applications

A testing method driven by Activity Diagram ( AD) model for Web applications was proposed. This approach generated test sequences from activity diagrams that satisfied round-trip coverage criteria, generated test data that drive the execution of test sequences based on test input syntax, integrated test data to test sequences for test case generation, ran the test cases for Web application testing, and reported the test results. A prototype tool that supported the proposed approach was implemented. An experiment has been carried out to validate the feasibility and effectiveness of the presented approach.
