HI

  Test case is a minimal input designed to check the 
functionality of an application between expected and actual
result.
 or
 verification vs validation.

severity is a metric to measure the defect level 
it is oriented to Application .

priority is a metric to measure the defect level
oriented to customer or client.

Test cases  are the guidlines by which u can test the 
functionality of the application between expected and 
actual result.

Test cases written on the basis of client's requirement.

Seviority is a metric which  defines  the impact of the 
bugs on the application.

eg. suppose we are working on the banking project and 
during the execution found a bug related to interest of 
money  it means it has high seviority because it will give 
a financial  impact on the banking process.

Priority is related to Seviority if the seviority is high 
than priority will be also high.

How to test the functionality of the application in terms 
of input ,process ,output is called test case.

how much seriousness of the bug in terms of the 
functionality is called severity.

how much important to fix the bug in end-user point of view
is called priority

eg.calculate (2*3=6),but the answer is coming 7 instead of 
6 by using a calculater.
here we abserve that the functionality is working (when we 
press the 2,3,*,keys)but the answer is wrong means end-user 
point of view answer should be 6.here the severity is 
low,and priority is high.

Test case is a Document that describes an input,action or 
an event and its expected result.(This is the only correct 
defination)

e.g If a developer forgot to add Brand name of the client 

 for the client it is having high seviority and High 
priority.
 for the developer it is having low seviority and low 
priority.

Testcase is the document that we need to test the
functionality of the specific feature.

* Severity means How it is affecting the specific feature.
        Ex.: If we are not able to login, after correct
input of login and password.
         It means it is critical.

* Priority means How Quick the bug need to resolve.
        Ex.: If the name of the NOKIA is written as NOOKIA,
then it is P1 type Bug, allthough it is not affecting any of
the functionality of that company.
         It means it is P1 type Bug.

Test Case means where we while write the functionality of 
the application.

1.Seviority:- it means it gives the importance according to 
the defect.

2.Priority:- it means that how quickly the bug is fixed.
