Abstract: In order to guarantee Web duality and reliability, people attach more and more importance to Web application testing. Analyzing and understanding Web application, mastering inter control flow and data flow information, good structural testing models and methods can be built so as to carry out structural testing based on coverage rate. In this paper,an structural testing model that is five-level described as function level,function cluster level,object level,object cluster level and application level, was offered. Testing methods of designing and choosing test cases were also introduced so as to support structure testing of Web application.

Key words: Web application, Structural testing model, Web application testing
