Severity is defined as the extent to which a particular defect can create an impact on the software. Severity is a parameter to denote the implication and the impact of the defect on the functionality of the software.
Priority is defined as parameter that decides the order in which a defect should be fixed. Defect having the higher priority should be fixed first.
Difference between Severity and Priority in Testing:
|Severity is a parameter to denote the impact of a particular defect on the software.||Priority is a parameter to decide the order in which defects should be fixed.|
|Severity means how severe defect is affecting the functionality.||Priority means how fast defect has to be fixed.|
|Severity is related to the quality standard.||Priority is related to scheduling to resolve the problem.|
|Testing engineer decides the severity level of the defect.||Product manager decides the priorities of defects.|
|Its value is objective.||Its value is subjective.|
|Its value doesn’t change from time to time.||Its value changes from time to time.|
|Severity is of 5 types: Critical, Major, Moderate, Minor, and Cosmetic.||Priority is of 3 types: Low, Medium, and High.|
