With the rapid development of computer network technology, Web technology with its extensive, interactive, fast and interoperability features quickly swept the world, and has penetrated into all areas of society, the number of pages is rapidly growing exponentially. Driven by demand in the market, the Web is not only assume the task of simple data released, and including the construction of information systems and complex application logic, there have been many large-scale Web-based applications, the rapid development of Web technology, the scale of the Web program more The greater the structure of the Web system has become increasingly complex. Web program availability, reliability, interoperability and security issues, at the same time, more and more people's attention, and the increasingly stringent requirements. Traditional software testing techniques is difficult to achieve with the unique nature of Web applications testing, probing, testing methods and systems suitable for Web applications is the subject of today's software industry challenging. At present, the Web program to test a lot of research, made some preliminary research results, and the formation of a number of methods, tools and strategies, but mainly concentrated in the performance testing, security testing, the function of the system for Web little research, especially the entire Web application testing modeling. In this paper, the main methods and basic types of Web testing, and conducted in-depth research and analysis of existing test model to study the new features of the existing Web technology and web systems. New features for Web system, in accordance with the \grouping together, form a Web function block. Based on state transition test method is an effective way to detect the dynamic behavior of the Web program. By improving the existing Web test method for complex dynamic Web application page, a new event-based test model, focusing consider single-page internal event-driven state transition and technical conditions applied to the current Web application system to meet the test of the Web management information system modeling needs. Model systems, modules and page three levels of the Web system modeling, considering navigating relationships, the dynamic behavior of the data stream and procedures that describes the Web system architecture, system-level Web application diagram (WARD), module-level Web applications Relations The diagram describes the structure of the Web module, with a description of the internal structure of the complex dynamic page event-based Web page state transition diagram (WSMD). WARD is the evolution of the map, the main transformation navigation relationship is broken down into four categories, namely, switching calls relationship embedded call, the lock call pop pop-up calls and asynchronous relationship. WSMD mainly consists of a set of states, a set of events and state transition set constructor extract key tag in the Web page, build a set of states, analysis of Web pages that can be triggered by events, analysis of event response function, extracting events controlled conditions call table, so as to establish a set of events, event execution, causing state transition, and build a state transition set. Event test model-based modeling process, Chongqing Electric Power Company power dispatching management information system for the experimental background, experimental model defects and deficiencies found in the experiment, was amended and improved. The experiments show that the event-based test model comprehensive and accurate modeling of the Web system, there are some practical value.
