failure n. 1.失败 (opp. success); 不及格。 2.不足,缺乏;衰退;【医学】衰竭。 3.不履行,玩忽。 4.破产,倒闭;(银行等的)无力支付。 5.失败的事;失败者。 6.【物理学】失效;【机械工程】断裂,破坏,变钝。 F- is the mother of success. = F- teaches success. 〔谚语〕失败是成功之母。 a failure of rain 雨量缺乏。 failure in duty 不尽职。 a crop failure = (a) failure of crops 收成不好,歉收。 failure of electricity 停电。 a failure of issue 无后(嗣)。 failure of eyesight 视力减退。 He is a failure as a teacher. 他教书不行。 heart failure 【医学】心力衰竭。 a social failure (社会上的)失败者。 end in failure = meet with failure 终归失败。 invite failure 招致失败。
It seems that our inability to work more effectively with users to better understand their requirements , coupled with weak engineering discipline in managing requirements , is the leading cause of software failures 从表中可以看出,没有能够更有效地与用户一起工作以更好地理解他们的需求,加上在管理需求方面缺乏工程训练,是软件失败的主要的原因。
In practice , software failures are often affected by various factors , such as the operating environment , the testing method , the resource allocation , and so on , thus it is impossible for software failures to follow a same distribution 在实际情况中,软件故障经常受各种因素的影响,例如运行环境、测试方法和资源分配等,从而软件故障不可能服从同一分布,这就是移动点问题。
According to some distinct character of the software , the dynamic testing model that defines the test content and test environment is designed . and the software failure data is collected in the process of software testing simulation , which is realized by using the ibm pc assembly language to execute the test on pc 根据fmc执行软件所具有的实时性、嵌入式、余度计算、面向机器的语言、硬件依赖性及多机处理等约束条件,设计了软件测试内容及测试环境,建立了基于覆盖的动态软件测试模型。
First , this paper introduces the conception of software test , testability , and some existent model used for analyzing testability . second , we analyze the merits and demerits of each model , as followed , after we particularly investigating the process of software fault leading to software failure , we put forward our improved scheme ? stdm and specify the process that it measure software testability more logically . at last , based on stdm we design and implement a stds ( software testability detecting system ) , which can be used to measure the testability of c programs , and show the detected result in different level 本文首先介绍了软件测试和可测试性的基本概念等用于检测软件可测试性的理论基础,并详细分析了一些理论检测模型及各自的优缺点;接下来,针对这些可测试性检测模型中所存在的问题,根据对软件错误导致软件失效过程的研究分析,本文提出了一种改进的解决方案stdm用于对软件的可测试性进行量化检测,文章在最后设计并实现了构建在此stdm模型基础之上的一个软件可测试性检测工具,该工具能够对c源程序进行可测试性检测并得出量化结果数据,验证了该模型的有效性。
