Error: It is the term used to describe a non-conformance to
the explicitly stated requirement.
For example: Let me explain with an example. If the
requirement mentions 5 Plus 3 Divided by 4; the programmer
codes to add 5 and 3 first; and then divides the result [8]
by 4 to arrive at result 2.
But if the actual/intended application requirement is to
first divide 3 by 4 and then add 5; expecting a result 5.75
then this is a classic Design/Code Error.
Bug: Assume that the programmer has actually understood the
intended requirement correctly but has declared/stored the
result as an integer to show a result of 5 instead of 5.75 –
this is called a Bug. Here the programmer has to declare the
variable as “double or float” and not “int”.
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”.
error: means mistakes in the program
bug:means if the error is rectified it is called bug
defect:if the error is not rectified it is called defect
small example for above scenario:
take a pen it consists of cap,stiker....if stiker is lost
that is called (ERROR),u can replace it with another stiker
that is called (BUG),if pen has hole we can't replace
it ,in that condition we called as (DEFECT)
the terms error,bug,defect are nearly inter connect to each
other.
error:mistake in the program
defect:mistake found by the test engg is called defect
bug:if the defect is accepted by the developer is called
BUG: in other words Expected result not equalto Actual
result is called bug,

If in the Req it is to first divide 3 by 4 and then add 5;
Error : the programmer codes to add 5 and 3 first and then
divides the result ( calculation is not doone as mentioned
in the req )
Bug: programmer understands but declares the variable
differently ie in this case, it must be double or float
but declares it as int.
Defect:deviation from the requirement specification
Bug:deviation from the Functional specification
Error:related to source code like syntax error,logical
error etc
In an interview point of vie all these sounds same which
interrupts the succesful execution and expected out. But in
general
Error: i sthe mistake performed by the developer like
syntax error
Bug: is the deviation between the Actual out put and the
expected output.
Defect: Bugs that are accepted by the developer is called
defect
error : A mistake in a coding is called error
defect or issue: due to errors in coding testing engineers
are getting mismatches of our app. build this is defect or
issue
bug: these defects or issues are accepted by the developers
then it is bug.
Error: problem related to a program is called error.
Defect: problem that is identified by testing department is
called defect.
Bug:error that is identified by development department is
called bug.
In my opinion error and bug are same.
What is the actions will be taken after preparing and
reviewing test cases. Directly we will go for execution and
how can we know the status of the application(whether the
build is completed by unit testing).After unit testing
completed, what are the next steps????
What is User Acceptance testing and when u'll do this and
who will do this testing.
If u got any bug while doing UAT what would be the status
of Severity and Priority?
What is a TEST CONDITION?When it is used?who prepares tesst
conditions?
Also pls explain me clearly with an example.Plsss reply me
fast. Thanks for the repliers.
