       Severity Vs Priority

  • Severity and priority in Software Testing

    In the Defect Tracking system Priority and Severity are used to share the importance of a bug among the team and to fix it accordingly.


        • The degree of impact that a defect has on the development or operation of a component or system.
        • Severity defines how severe will be the impact of a defect on the performance of the system.
        • Defect Severity is one of the most common causes of disputes between Testers and Developers.
        • Severity means how severe it is affecting the functionality.
        • Severity is associated with standards.
        • The Test Engineer can decide the severity level of the bug.
        • Based on Bug Severity the product fixes are done.
    Severity and Priority

    Severity Type





    Cannot able to test application further. (Show stopper)



    Major functionality not working but able to test application



    Bug in Functionality but in the sub module or one under the other module.



    Issues in location of the object or the look and feel issue (Cosmetic)


        • Priority means how fast it has to be fixed.
        • Product manager is to decide the Priority to fix a bug
        • Priority means how urgently the issue can be fixed.
        • Priority status is set based on the customer requirements
        • Priority actually tells the developer the order in which defects should be resolved.  






    immediate attention and should be resolved as soon as possible.



    should be resolved soon after the defects with higher priority have been resolved.



    does not require immediate attention and should be rectified after the defects with higher priority have been resolved.

    High priority and High severity

        • Basic functionality of the system is affected and user is blocked as user is unable to use this application
        • Such defects should be rectified immediately.

    High priority and Low severity

        • For example Spelling mistake in the company’s name or issues with logo.
        • Such defects are of low severity
        • But these needs to be fixed immediately and should be considered as high priority defect.

    Low priority and High Severity

        • Major defect in some module but user would not be using it immediately
        • This can be fixed later

    Low priority and Low severity

        • Generally cosmetic in nature
        • Doesn’t affect the functionality of the system
        • Can be fixed later
