Answer Posted / varshab
Bug & defect is same.many people think that these are two
different things.If you still have any doubt abt it You can
refer ISTQB syllabi for it.These are just two terms used
for same thing.It is also called as Incident or Fault.
Bug/Defect : It is flaw in component or system which can
cause component or system to fail to perform its required
operation.
You should also know defination of error & failure to
understand these terms clearl.
Error : Incorrect human action.
Failure : Departure from expected behaviour.
User made mistakes while using software that result in
error.then because of this error system fails to perform
its intended operation so it leads to defect/Bug .If these
Bug occured during execution system can fail so bug leads
to failure of system.
Error-> Bug - > Failure.
