What is severity and priority of bug? Give some example.

Answer

Priority: concern with application from the business point of view.
It answers: How quickly we need to fix the bug? Or How soon the bug should get fixed?
Severity: concern with functionality of application. It deals with the impact of the bug on the application.

How much the bug is affecting the functionality of the application?

Ex.

• High Priority and Low Severity:
  Company logo is not properly displayed on their website.
• High Priority and High Severity:
  Suppose you are doing online shopping and filled payment information, but after submitting the form, you get a message like "Order has been cancelled."
• Low Priority and High Severity:
  If we have a typical scenario in which the application get crashed, but that scenario exists rarely.
• Low Priority and Low Severity:
  There is a mistake like "You have registered success" instead of successfully, success is written.
