Back-to-back testing involves cross-comparison of all responses obtained from functionally equivalent software components. Whenever a difference is observed it is investigated and, if necessary, a correction is applied. Events associated with back-to-back testing process are defined and examined. The process is first modeled assuming failure independence, and then, assuming failure correlation. It is shown that multiversion testing involving more than four versions, offers rapidly diminishing returns in terms of failure-detection effectiveness, unless additional versions reduce the span of correlated failures. It is also shown that back-to-back testing can remain an efficient way of detecting failures even when the probability of identical and wrong responses from all participating versions, is very close to one作者: 鬼柳 时间: 2007-10-26 14:22

我知道是怎么回事了，指不同版本之间的比较测试，我们现在做的项目应该就属于这种情况：之前的版本使用c#开发，后来按照原有的功能转换成.net版本，然后比对原有的c#版本对.net版本进行测试，这就是back-to-back testing
