Severity and Priority of Defects.
There are two
important things related to defects of software testing :
- Severity
- Priority
Severity:
Severity is the
extent to which the defect can affect the software or application. Severity
defines the impact of defect on the system or software. Example: When user
clicks on a remote link and the page of application crashes. Being it the
remote link on the application the Priority of the defect will be low however
the severity will be high.
Critical: The defects
or bugs that can result in termination of the complete software or one or more
components of software are categorised as of Critical Severity the failed
function is unusable and there are no alternative methods to do that work.
Major: The defects or
bugs that results in stoppage of complete system or one or more module of
software. The failed function is unusable but there are alternative ways to do
that work.
Moderate: The defect
or bug doesn’t stop or terminate any functionality but caus causes the software
to produce incorrect or inconsistent output.
Minor: The defects
that causes no termination or stoppage of the system. The desired outputs can
be obtained by another available function.
Cosmetic: Cosmetic
defect is related to the changes related to look and feel of the application.
Priority:
Priority defines the
sequence in which the defect should be resolved by the developing team. The priority
of the defects is set by tester to developer having the time frame to fix the
bug. The priority of the defect is set on the basis of customer requirement.
Priority can be of
the following types:
Low: The priority of
the defect is set as low when the defect is an irritant and can be fixed later
after more serious defects.
Medium: The priority
of defect is set as medium when the defect can be fixed in normal course of
development.
High: The priority of
defect is set as high when the defect is affecting the software or product
severely. The system is unusable without the defect is fixed by dev team.
Interview Question
related to Severity and Priority:
High Priority and
High Severity: Defect which occurs on basic functionality of the software and
is not allowing the user to use the system or software.(Example: a website
having details or students, when the user saves a record it doesn’t allows the
user to save the new record.)
High Priority and Low
Severity: The spelling errors on the cover page or main page of a website or
application.
High Severity and Low
Priority: Defect which occurs on the functionality of the software which doesn’t
have any work around and is not allowing user to use the system on click of a
remote link.
Low Priority and Low Severity:
Any cosmetic defect on a paragraph or in report not on cover page or heading.
