问题 问答题

简述系统测试的主要步骤。

答案

参考答案:

解析:系统测试工作按模块测试(单调)、子系统测试(分调)、系统测试(联调)和验收测试四个步骤进行,具体内容如下: (1) 模块测试。模块测试是对单个模块进行的测试,目的是保证每个模块作为一个单元能够正确运行。通常情况下,模块测试方案设计比较容易,发现的错误主要是编码和详细设计方面的错误。模块测试比系统测试更容易发现错误,能更有效地进行排错处理,是系统测试的基础。 (2) 子系统测试。子系统测试是在模块测试的基础上,将测试过的模块组合起来形成一个子系统进行测试。子系统测试主要解决模块问的相互调用、通信问题,所以测试重点在接口方面。子系统测试通常采用自顶向下和自底向上两种测试方法。 (3) 系统测试。在所用子系统都成功测试之后,将它们组合起来进行的测试就是系统测试。系统测试主要解决的是各子系统之间的数据通信、数据共享问题,测试系统是否满足用户要求。系统测试的依据是系统分析报告,要全面考查系统是否达到了设计目标。系统测试可以发现系统分析遗留的未解决问题。 (4) 验收测试。在系统测试完成后,要进行用户的验收测试。验收测试是把系统作为单一的实体进行测试,它是用户在实际应用环境中所进行的真实数据测试。与系统测试的内 * * 本一致,测试要使用手工系统所用过的历史数据,将运行结果与手工所得相核对,考查系统的可靠性和运行效率。

Here’ s an unusual story: a diamond ring

was recently found in an egg. The    

magician, Liu Qian, discovered it, in front          

of an audience of millions at CCTV’ s Spring

Festival Gala. Liu’ s magic tricks have made the centuries-old art of magic fashionable once again, and made him the hottest magician in China.

As a seasoned young magician from Taiwan, Liu is popular worldwide for his magic shows. Countries he has performed in include the U

nited States, Japan, South Korea and the UK.

Witnessing something impossible happen right before your eyes is the root of people’ s love for magic.

“It’ s actually thinking rather than one’ s manipulation(操作)skills; that is more important to achieving a successful magic show. We think carefully about how to design the shows creatively, to make them appear more interesting.  ”Liu said.

Liu Qian’ s success dated back to his childhood. Born in 1976 in Taiwan, he found himself attracted to a magic toy in a shop when he was seven years old. At the age of 12, he won Taiwan’ s Youth Magic Contest, which was judged by the great American magician, David Copperfield.

Yet, Liu never planned on becoming a professional magician. He studied Japanese literature at university and only hoped to be an amateur  (业余的) magician in his spare time. However, his failure to find a proper job after graduation pushed him towards magic as a career.

To refine his performing skills, he has performed on streets, roads and fields for passers-by, policemen and farmers.

“Street shows are the biggest challenge for us magicians. We have to deal with unexpected situations and tough crowds, ” Liu said.
