Difference Between Error And Failure
it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the top What's the difference between fault, error and defect? [duplicate] up vote 9 down vote favorite 5 Possible Duplicate: Difference between defect and bug in testing In computer science technical writing, especially in software engineering, what's the difference between fault, error software errors, faults and failures and defect? I want to quote an answer on Stack OverFlow by Daniel Joseph: To quote the Software Engineering Body of Knowledge Typically, where the word “defect” is used, it refers to a “fault” as defined below. However, different cultures and standards may use somewhat different meanings for these terms, which have led to attempts to define them. Partial definitions taken from standard (IEEE610.12-90) are: Error: “A difference…between a computed result and the correct result” Fault: “An incorrect step, process, or data definition in a computer program” Failure: “The [incorrect] result of a fault” Mistake: “A human action that produces an incorrect result” Based on my understanding of above definition, error is the result of fault, i.e., failure.

Fault From what I've come to understand, a Fault in this context would be a flaw in the code's written logic. So in this case the Fault would be the fact that the code instructs the computer to start iterating over all elements of v with a start index of 1 instead of the expected 0. Error When running the above method, we always get an Error but in once instance (when v.length == 0), as what we really want is to iterate over all elements of x, but since we're starting with i = 1, that is not really happening. With an empty vector as input, as we don't enter the for loop, so our incorrect code isn't run, meaning that the Error doesn't happen, and everything happens as should in theory. Failure Since our code has a Fault that in execution-time will almost always manifest in a Error, we only have a Failure when we effectively see the incorrect output. Assuming that an Error effectively happened in my pro
