How Can You Assign a Bug Severity ?

Do you write test cases for regression testing?
Yes we will write regression test cases.... Regression is nothing but when new functionality is added then we r doing regression testing... so we r writing test cases for new functionality and we will write test cases like P1 for regression test


What is Defect Seeding?
In this method, intentionally the developer/lead will introduce the bugs in to product... we don’t know in which Module they will occur... So we have to do regression testing to identify that bugs as well as residual bugs(more Bugs). The main intention of this is to get more bugs.

What is concurrency testing?

It means testing the software with anticipated load levels For the purpose of identifying problems in recourse Contention, Response times etc

Rate Bug Severity
High severity-- in any application the application will be Crashed with multiple use any funcnality for ex add button Use 200 times. The application will be crashed so we can Give high seveiority.low priority’s there is no need to Debug it right now u can debug it after some days.
Lowest severity and highest priority. -- For ex the yahoo Website spelling is mistake the spell is yahoo. So here we Can give high priarity.because it will affect the site
Name. So we have to give the quick priority. But here we Can give low severity .the spell change is not going to The application crash.

Low level bug is also called as cosmetic bug. I.e. if there Is change in the spelling or color mistake then we call it As low level bug. It will be having low severity (s1). And
Priority is p5 (i.e. before delivery we can fix the error)

Medium level bug: if there is any mismatch with the Expected and actual values then we call it as medium level Bug, here the severity is s2. And priority is p4 (i.e. with
In a week)

High level bug: It is an unexpected error or output, and the Severity is s3. And priority is p3 (i.e. with in 2-3 days)

Very high or major level bug: any fatal error or the module Crashes while running the application we call it as high Level bug. Severity is s4 and priority is p3 (i.e. with in a Day)

Urgent or Critical bug: application crash, severity is s5 And priority is p1 (i.e. it has to be fixed with in 2 to 3
Hours)


What is difference between GUI and Usability Testing?

GUI Testing is nothing but testing the design of the Application. I.e. the properties of the Buttons and Text box Etc.

Usability Testing is nothing but the application is user Friendly or not. I.e. easy to use and easy to operate.
