问题 单项选择题

下列叙述中正确的是

A.软件测试的主要目的是发现程序中的错误

B.软件测试的主要目的是确定程序中错误的位置

C.为了提高软件测试的效率,最好由程序编制者自己来完成软件测试的工作

D.软件测试是证明软件没有错误

答案

参考答案:A

解析: 本题考查软件工程中测试的目的和方法。仅就软件测试而言,它的目的是发现软件的中的错误,但是,发现错误并不是最终目的,最终目的是通过测试发现错误之后还必须诊断并改正错误,这就是调试的目的。由于测试的目标是暴露程序中的错误,从心理学角度看,由程序的编写者自己进行测试是不恰当的。因此,在软件测试阶段通常由其他人员组成测试小组来完成测试工作。因此,经过上述分析可知选项A的说法是正确的,而选项B、C、D的说法是错误的。
