Q: What is severity?
A: Severity will be a status about a written program, can be like it is technical disturbance review process. How much issue make technical behavior disturbance then will be defined by one of status low, medium and high.
In a written program there may be any type of problem and due to that program won’t work according to requirement and on that condition QA team will define the status of issue, means what type of mistake is there as per technical view.
For instance taking a simple module to be cleared more, like a “sign up” module is developed by development team and shared to QA team for verification now during verification process QA team found “sign up” feature is working but an invalid value is being passed for “email id” like “example@examplecom” ( without dot ), it means when further user will try to login then probably user won’t be able to login may be user will try correct email id and due to proper restriction to “login form” user won’t get access then further will try to “forget password” then it will also not work. So means “severity status will high”.
