下面关于软件测试模型的描述中,不正确的包括(21)。①V模型的软件测试策略既包括低层测试又包括了高层测试,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

  6. ?People are including in an illusion whenever they find themselves explaining at a cocktail(鸡尾酒)party , say , that they are “in computers,” or “in electronic funds transfer”. the implication is that they are part of the high-tech world, Just between us, they usually aren’t. The researchers who made fundamental breakthroughs in those areas are in high-tech business. The rest of us are__(71)__of their work. We use computers and other new technology components to develop our products or to organize our affairs. Because we go about this work in teams and projects and other tightly knit working groups(紧密联系在一起的工作小组),we are mostly in the human communication business. Our successes stem from good human interactions by all participants in the effort, and our failures stem from poor human interactions. The main reason we tend to focus on the __(72)__rather than the human side of the work is not because it’s more__(73)__, but because it’s easier to do .Getting the new disk drive installed is positively trivial compared to figuring out why Horace is in a blue funk(恐惧)or why Susan is dissatisfied with the company after only a few months. Human interactions are complicated and never very crisp(干脆的,干净利落的)and clean in their effects, but they matter more than any other aspect of the work. If you find yourself concentrating on the __(74)__rather than the __(75)__,you’re like the vaudeville character(杂耍人物) who loses his keys on a dark street and looks for them on the adjacent street because, as he explains, “The light is better there!”.
