摘    要:软件的可靠性估计、程序结构及测试之间存在着重要的联合,针对一个程序及其输入值有限集,可以由测试来处理所精心定义的程序状态。但是,程序测试的基本理论仍不明了,其部分原因是测试的目标不明确,对测试或者测试方法的评价也没有统一的标准,测试不应该以纠错为最终目标,其最终目标应该是精度量被估测软件的可靠性。其于这个目标,需要提出蝗可信度理论,并以它为基础,明确应该使用什么样的测试方法及测试环境。目前可信度理

关 键 词:可信度理论  可靠性  软件测试  软件开发

Dependability Theory and Testing

Abstract:There are important internal relations among software reliability, program structure and testing. Over a finite collection of input values, testing deals with the well defined situation of a fixed program. However, the fundamental theory of testing is in disarray. Part reasons are a confusion of testing goals and assessments for test method. Testing's primary goal is not to check errors. It should be to measure the dependability of tested software. In support of this goal, it is necessary to suggest dependability theory and also necessary to know what test methods and what circumstances should be used. The outlines of dependability theory are not yet clear.
Keywords:Dependability Operational profile Reliability Failure intensity
