What is reverse debugging? Classification of reverse debugging methods

Abstract The article discusses an approach to speeding up the search complex errors in software – reverse debugging. In this approach, debugging is divided into two phase. The first phase is to save the behaviour to a log file. The second phase is the reproduction of behaviour and the search for errors. During the second phase, both past and future program states can be examined. The article describes methods that support this approach and general principles for such methods and their differences. A classification of reverse debugging methods is proposed by debugging scope and replay scope. Examples of modern reverse debugging tools and their place in the proposed classification are given.
