In this article I have tried to collect the different definitions of a defect or a software bug. It seems to be something elementary, but it is fundamental, so it is sometimes useful to come back to it.
“Rapid testing” by Robert Culbertson, Chris Brown, Gary Cobb: Software error is no more than a flaw in software development, which causes inconsistency of expected results of a software product and in fact the results obtained.
“Testing Dot Com, or benefit the abuse of bugs in Internet startups” Roman Savin So, the bug is a deviation of the actual result on the expected result. In accordance to the law of excluded of the third we have a bug if there is any actual result differs from the expected.
Wikipedia In general, developers differentiate software defects and failures. In case of failure, the program does not behave as you expect. Defect – an error / inaccuracy, which may (or may not) be a consequence of the failure.
My definition Defect is the behavior of the program which makes it difficult or impossible to achieve the goals of user or satisfy the interests of participants. It implies the possibility of correction. If you cannot fix it goes into the discharge limits of technology. “The interests of members must be understood” in the sense of A. Coburn.
