问题 单项选择题

下列叙述中正确的是______。

A.软件测试应该由程序开发者来完成

B.程序经调试后一般不需要再测试

C.软件维护只包括对程序代码的维护

D.以上三种说法都不对

答案

参考答案:D

解析:程序调试的任务是诊断和改正程序中的错误。它与软件测试不同,软件测试是尽可能多地发现软件 中的错误。先要发现软件的错误,然后借助于一定的调试工具去找出软件错误的具体位置。软件测试贯穿 整个软件生命期,调试主要在开发阶段。为了达到更好的测试效果,应该由独立的第三方来构造测试。因 为从心理学角度讲,程序人员或设计方在测试自己的程序时,要采取客观的态度是程度不同地存在障碍的。 软件的运行和维护是指将已交付的软件投入运行,并在运行使用中不断地维护,根据新提出的需求进行必 要而且可能的扩充和删改。
