Web系统性能测试研究与实践

RESEARCH AND PRACTICE OF WEB SYSTEM PERFORMANCE TESTING

随着Internet技术的日益发展,Web系统应用越来越广泛,面向的用户群体也日益庞大。系统的复杂性及用户操作的不确定性,对系统性能提出了更高的要求。在Web系统上线发布之前,对其开展性能测试,及时发现不足,为系统正式运行提供质量保障。介绍性能测试的原理、指标及测试场景的选择等,并使用Silk Performer性能测试工具测试企业外部网站系统。实验结果表明,性能测试可以模拟和预测真实环境中对系统的压力,将系统中存在的问题暴露出来,有助于问题的定位与解决。

With the growing development of Internet technology,the applications of Web system are increasingly popular,and the user groups it faced are also getting increasingly large. The complexity of the system and the uncertainty of users＇ operation put forward higher requirements on the performance of the system. To carry out performance test before the Web system is on-line released can find problems and provide quality assurance for the system. In this paper we introduce the principle,criteria and test scenario selection of performance test,and test an external website system of the company using Silk Performer performance test tool. Experimental results show that the performance test can simulate and predict the pressures on the system in real environment,and expose the problems existed in the system,these are helpful to orientate and solve the problems.
