问题 单项选择题

广义的软件测试由“确认”、“验证”、“测试”三个方面组成,其中“确认”是()

A.想证实在一个给定的外部环境中软件的逻辑正确性,检查软件在最终的运行环境上是否达到预期的目标

B.检测软件开发的每个阶段、每个步骤的结果是否正确无误,是否与软件开发各阶段的要求或期望的结果相一致

C.检查某样东西是否符合事先已定好的标准

D.试图证明软件在软件生命周期各个阶段以及阶段间的逻辑协调性、完备性和正确性

答案

参考答案:A

解析:

本题考查对广义软件测试中“确认”和“验证”概念的了解。

“确认”和“验证”两个概念比较容易混淆。确认(Validation)是“确认工作产品完全提供了用户想要的功能,检验产品是否真正提供了用户想要的东西。”确认更多是从用户的角度,或者是模拟用户角度来验证产品是否和自己想要的一致。确认是想证实在一个给定的外部环境中软件的逻辑正确性,并检查软件在最终的运行环境上是否达到预期的目标,而不是检查软件是否符合某些事先约定的标准。验证注重“过程”,确认注重“结果”。所以答案A是正确的。

According to the dictionary definition of“create, ordinary people are creative every day”.To create means“to bring into being, to cause to exist something each of us does daily”.

We are creative whenever we look at or think about something in a new way. First, this includes an awareness of our surroundings. It means using all of our senses to become aware of our world. This may be as simple as being aware of color and texture(质地),as well as taste, when we plan a meal. Above all, it is the ability to notice things that others might miss.

A second part of creativity is an ability to see relationships among things. If we believe the expression,“There is nothing new under the sun, the creativity is remaking or recombining(重组) the old in new ways.”For example, we might do this by finding a more effective way to study or a better way to arrange our furniture, or we might make a new combination of camera lenses and filters to create an unusual photograph.

A third part of creativity is the courage and drive to make use of our new ideas, to ask for them to achieve some new results. To think up a new idea is one thing; to put the idea to work is another.

These three parts of creativity are included in all the great works of geniuses, but they are also included in many of our day-to-day activities.
