Bug Vs Defect 

 

Error : Is an undesirable deviation from requirements

Bug : Is an error found BEFORE the application goes into production

Defect :Is an error found AFTER the application goes into production

 Any deviation from requirement is a bug , which may or may not cause failure. But defect is the one which wil cause the software failure. I mean a software can run without failure with bugs in it. But a software cant run withour failure with defects in it.

Bug: The codes are developed

Bug: The codes are developed as per the requirements still the expected results are not obtained then it is called BUG

Defect: The Codes are developed and still the expected results are not obtained due to the non conformance of requirements then it is called defect

Kindly correct me If I am wrong

Hi Kishore, AFAIK, The

Hi Kishore,

AFAIK, The description for the term Defect is not as u said.

ERROR = A mistake found during the development/coding of the application.
ISSUE = In the application is any deviation/Mismatch we observed otherthan the Expected Result.
DEFECT = An issue logged in Quality Centre.
BUG = The Defect accepted by the development called BUG.
FAILURE = This is the term i heard many times if there is any mismatch in Production (after the app's goes to prod.)

Many people have their own kinds of definitions on this terms. I never heard an error error occured in production is called as Defect. Totaly its a failure of that app's.

You are always welcome to reply/comment on this post.

Thanks,

Bug is any inconsistance

Bug is any inconsistance with requirement, where defect scope is higher than bug, its the inconssitancies of requirement associating with severity, priority, root cause, to the specifice bug, it's reffered as defect.
