问题 单项选择题

下面关于软件测试模型的描述中,不正确的包括()。①V模型的软件测试策略既包括低层测试又包括高层测试,高层测试是为了源代码的正确性,低层测试是为了使整个系统满足用户的需求②V模型存在一定的局限性,它仅仅把测试过程作为在需求分析、概要设计、详细设计及编码之后的一个阶段③W模型可以说是V模型自然而然的发展。它强调:测试伴随着整个软件开发周期,而且测试的对象不仅仅是程序,需求、功能和设计同样要测试④H模型中软件测试是一个独立的流程,贯穿产品的整个生命周期,与其他流程并发地进行⑤H模型中测试准备和测试实施紧密结合,有利于资源调配

A.①⑤

B.②④

C.③④

D.②③

答案

参考答案:A

解析:本题考查对软件测试模型的了解。在题干所述第①点中:低层测试应该是为了源代码的正确性,高层测试应该是为了使整个系统满足用户的需求:第⑤点中:测试准备和测试执行应该是分离的,而不是紧密结合的,所以有利于资源调配,降低成本,提高效率。①和⑤都不够准确,所以答案是A。

     Phoenix , Arizona, the USA was shaken by a big sandstorm recently. It was a huge dust storm that
