标题: Definitions: Errors, fault, failure and defect [打印本页] 作者: sanjieyu 时间: 2006-8-10 15:08 标题: Definitions: Errors, fault, failure and defect We used Error,fault,failure and defect during our testing.
What is the definiens for these?
Defect including: Errors, fault and failure
· Errors: A human action that produces an incorrect result
· Fault: An incorrect step, process, or data definition in a computer program
· Failure: The inability of a system or component to perform its required functions within specified performance requirement.
So it is not one to one corresponding relationship between the Error, Fault and Failure..
For example, A dev made a contrived mistake, such as he changed one control name in one place but forget to change it in other places, this called Errors. So the program maybe has some faults now, at last, when execute the program, maybe have some failure.
QA submit Failures and Dev fix Errors, so sometimes Dev will complain many bugs are due to the same Error reason, that is maybe one Error can cause many Failures, so the important thing is QA should better analyze the issues before he submit作者: xiaonan 时间: 2006-8-10 17:39
