Design And Implementation Of A HTTP/S Protocol Based Web Performance Testing Tool

Nowadays, testers focus on Web application system performance. Because manual performance testing has many fatal defects, performance testing tools have been widely used. These tools usually create and run virtual user script to simulate the effect the same as the real users' operations in order to make special stress on Web application system based on many protocols such as HTTP/S etc. . In the meantime, testers use performance monitor tools and timers to record the performance of Web application system under special stress and Web application system response time feeled by the browser-side users. Finally performance testing tools achieve performance testing and analysis report and provide the testers with plenty of testing and analysis data.In this thesis, we introduce the Web performance testing, compare and analyze the Web performance testing tools used in IT field, and summarize the necessarity of research on Web performance testing tool. We make some research on recordingand playbacking, virtual script, stress and load testing, performance monitoring and testing report making. We put forward the design and implementation scheme of Web performance testing tool, and then implement the Web performance testing tool based on HTTP/S protocol — Performance Testing Tool (Web). Further more, we make some functional and performance optimization, and improve the efficiency of Web performance testing.In this thesis, we put forward a Web replay model WRM used to assess replay browser. We makes a quantity comparison between these two web replay browsers using WRE based on the function comparison between Performance Testing Tool (Web)'s BView and LoadRunner's Run-Time Viewer replay browsers, and then draw a conclusion.In this thesis, we illustrate the using of Performance Testing Tool (Web) and performance testing flow, and put forward the direction of Web performance testing tool research and development. Finally we summarize the works done in this thesis and needed to deal with in the future.
