Answer / param gates

Let me explain with an example.

If input is 2+2, then output is an error message, it is
error(syntax error).

If input is 2+2, then output is 5, it is bug(logical error).

If the program is for addition and subtraction, and only
addition is there and subtraction is left out, it is defect.


Usually the error is found by developer.

Usually the bug is found by tester.

Usually the defect is found by client or user.

Answer / krish

Bug- Bug should be found during testing the application

Error:It is a non-conformance to the explicitly stated
requirement. It should be found during unit testing or
compiling the code

Defect: A defect is any of the above but found/un-covered in
the “released-application” - running in the “Production
Servers” [gone “Live”] or may be in “Beta-Release”.

Fault: When the application runs without any issues in the
intended Production Environment under normal circumstances
but misbehaves after continuously running for about a month
or after performing about a million transactions then we
call this condition as Fault.

Answer / jai

Bug is from tester's perspective

"The output that deviates from the actual requirement
(SRS). In that case tester call it a bug and developer call
it a defect."

Defect is from developer's perspective

Error occurred while coding or some logical error.

Failure &fault is same and can be difined as when client
fails to get the required results during acceptance testing
he/she termed it as failure/fault.

Feel free to comment
Thanks

Answer / jyothi

bug:its an informal name given to defect.
error:this terminology is used by developers,they may get
compile time error or run time error.
failure:defect leads to failure of bussiness...

one defect may leads to multiple failure or one failure..
these are the differences i feel.

Answer / prashant tangle

Error: it is human mistake, probably you can say that
developer has done a mistake i.e. error in code.

Fault: It is unexpected result due to above mistake, you
can say that due above error in code there is fault at the
system or application.

Failure: It can occurs due to fault(s) at system, say that
due to multiple faults system fails.

Defect: It is purely finding a fault in the system, it can
be a bug.

Answer / s. u

Defect: Found by Developer
Bug: Found by Tester
Error: Error in the software
Failure: Found bu Client

Answer / vinita patidar

Hi,

Defect,failure, fault all are bug.But the major difference are:

When tester find any bug in software is called defect.

when developer find any bug in software is called failure.

When customer find any bug in software is called fault.

You get the build directly from the developer or through tl,if so how?
