Web负载测试的研究与应用

Web应用对并发服务性能的严格要求决定了对其进行负载测试的必要性。通过分析B/S系统结构模型和Web应用的服务形式，确定了Web负载测试的理论基础和可行性，并建立了测试模型。以OpenSTA为例介绍了当前主流自动化Web负载测试工具基于脚本的工作机制和测试步骤，讨论了对测试结果数据的分析与可视化方法，并总结了评估Web应用系统性能的主要指标。

Research and Application of Web Load Testing

Web applications have critical demand on large-scale concurrent serving ability,which determines the importance of Web load testing.This paper analyzes the structure model of B/S system and serving formation of Web applications,through which the theoretical fundamentals and feasibility of Web load testing are given, and a testing model is built. The working mechanics of OpenSTA and procedures of using it are introduced as an example of mainstream automatic Web load testing tool.At last the analysis and visualization methods to the testing results are discussed,as well as some indexes of performance.
