基于虚拟实验室的压力测试方法与服务平台

摘要

This paper analyzes the characteristic, method and tools of load testing for current information systems. A load testing process based on VLab that is different from the common load testing process is brought forward. Then a basic archi-tecture of load testing service platform based on Vlab is described and the strategy of building the platform is analyzed. For the purpose of verifying the feasibility of platform implementation, a small scale platform is built by COTS tools and self-developed program and the test is executed contrast to the common platform. Experimental results show that the load test-ing service platform based on Vlab can ensure the validity of test results, and promote the test efficiency at the same time.%分析了当前信息系统软件压力测试的特点、方法和工具，提出了与一般压力测试过程不同的基于虚拟实验室（Virtual Laboratory，Vlab）的压力测试过程。在此基础上，描述了一个基于Vlab的压力测试服务平台的基础架构，对平台构建的策略进行了分析。为验证平台实现的可行性，利用COTS工具并结合自主开发构建了一个小规模的压力测试服务平台，与一般压力测试平台进行了对比测试。实验结果表明，基于Vlab的压力测试服务平台能保证测试结果的有效性，同时提高测试效率。
