5 系统测试
开发进入后期，一个关键性环节就是测试，这关系到最终开发质量。针对软件测试，实质上就是在给定环境下，进行系统实际运行，并对运行质量与结果进行评估的活动，这里的给定环境包括正常与非正常两种条件，通常来说，软件测试会有意识的或主动性的去促成错误出现，从而基于此进行针对性观察确定系统稳健性和可靠性，因此软件测试可以在某种程度上等同于软件问题探测过程。
5.1 系统测试的意义和功能
曾经整个软件界都在关注所谓的软件危机现象，并付出巨大努力试图彻底将其解决，但随着技术与理论深入，开发者逐渐认识到没有真正意义上的软件危机存在，本质上这就是指软件运行过程的一种错误状态，并造成软件开发失败或成本等控制环节失控。软件无法完全根绝错误性，这是因为软件是人为造物，无法达到完美状态，因此核心问题就变成如何避免错误大量出现或如何有效解决已经形成的错误，并尽量抑制软件错误概率。
在整个软件开发过程及其正常生命周期中，都始终绕不开软件测试环节。在传统瀑布模型中，作为一种质量管理手段，软件测试学具有限制性适用场景，那就是在运行维护阶段之前，换言之就是开发结束与交付之前的一个最终检验环节。但是近年来出现了一些新变化，软件工程学理论有了新的发展，认为测试要放开限制性条件将其应用到软件生命全周期全环节，对阶段性成果注意进行效验，确定与预期符合度，从而对软件错误能够更早发现其源头，早期阶段测试的进行，将能够有效抑制错误扩散，并降低最后成品测试难度或复杂性。
事实上，软件测试只能尽量降低错误出现概率或密度，不管技术如何进步，错误仍然难以绝对避免，但是这也客观现实也并非意味着开发者不能采取手段去抑制错误密度及降低错误影响，如新语言、新开发方式等等，都将有效降低错误引入。而对于部分难以根据的引入错误，就需要通过测试手段及早发现，同时也需要对软件错误率进行一种评估，以保障最终开发结果的稳健性。工程学科不可或缺的组成单元，其中一个就是测试，也是开发环节必备手段，贯穿于程序设计整个发展历程。从统计数据来看，在整个开发过程中，软件测试工作量占比超过40%，同时测试开销占比也极高，一般能够达到30%到50%，当然如果把维护阶段也纳入到整个开发范围，那么测试成本占比会出现一定幅度下降，但很多时候维护实际上就是一种再开发，因此实际上也会涉及到测试工作。
