问题 问答题

[说明]
某公司需开发一套通用信息管理系统。为保证开发进度和开发质量,对开发的全过程进行测试,重点对模块和系统性能进行测试。

在测试准备会上,大家对测试目的和原则发表了以下观点:
A. 测试是为了证明程序无错
B. 因为在系统开发的各个阶段都可能出现错误,应尽早并不断进行测试
C. 开发人员对功能理解的错误很难由本人测试出来,因此,测试工作的主要过程应避免由开发人员来承担
D. 测试后软件中仍存在的错误概率与已经发现的错误数成反比
E. 成功的测试是发现了至今尚未发现的错误的测试
F. 严格的测试计划会使测试工作死板教条,影响测试进度
以上观点中正确的是 (1) (2) (3)

答案

参考答案:(1)B或因为在系统开发的各个阶段都可能出现错误,应尽早并不断进行测试
(2)C或开发人员对功能理解的错误很难由本人测试出来,因此,测试工作的主要过程应避免由原开发软件的人或小组来承担
(3)E或成功的测试是发现了至今尚未发现的错误的测试

解析:本题从软件测试的过程出发,考查对软件测试的基本概念、模块测试和系统测试的任务以及软件调试方法的掌握情况。
本问题考查对软件测试基本概念的掌握。
在6个备选答案中,A选项是错误的,因为测试的目的是查找软件中的错误,它无法证明软件的正确性。D选项是错误的,因为按照软件工程的基本观点,经测试后,软件中仍存在的错误概率与已经发现的错误数成正比。F选项是错误的,因为严格的测试计划会使测试工作有效地发现软件的错误,从而保障测试进度。其余选项是正确的。

单项选择题

(A)

Around the world more people are taking part in dangerous sports and activities. Now, there are people who look for an immediate excitement from a risky activity which may only last a few minutes or even seconds.

I would consider bungee jumping (蹦极) to be a good example of such an activity. You jump from a high place 200 meters above the ground with an elastic (弹性的) rope tied to your feet. You fall at up to 150 kilometers an hour until the rope stops you from hitting the ground. It is said that about 2 million people around the world have now tried bungee jumping. Other activities which most people would say are as risky as bungee jumping include jumping from tall buildings and diving into the sea from the top of high cliffs.

Why do people take part in such activities as these Some psychologists suggest that it is because life in modem societies has become safe and boring. Not very 10ng ago, people’s lives were constantly in danger. They had to go out and hunt for food, diseases could not easily be cured, and life was a continuous battle for survival.

Nowadays, according to many people, life offers little excitement. They live and work in quite safe conditions: they buy food in shops, and there are doctors and hospitals to look after them if they become ill. The answer for some of these people is to look for danger in activities such as bungee jumping.

Which of the following is true according to the passage()。

A. About 200,000 people in the world have tried bungee jumping.

B. In order to keep one safe, a rope is tied to feet of the jumping.

C. Diving into the sea from the top of the cliffs is much more dangerous than bungee jumping.

D. Many people nowadays feel life dull because they haven’t tried bungee jumping.
