Smoke test...

During the Stress Test:

Before going to this we should know what is meant by
Memory leakage?
Memory leakage means In some cases developers allocate
memory but forget to release it.
When a test is conducted for many days or weeks,
this problem results in allo-cation of all of the
available memory until no memory is left on hard disk.
This is the point where your soft-ware starts showing 
abnormal behavior.

Endurance testing checks for memory leaks or other problems 
that may occur with the prolonged execution.

Endurance Testing: Checks for memory leaks or other 
problems that may occur with prolonged execution.

Its a type of performance testing comes under stress 
testing. Mainly occures in embedded systems where Physical 
memery is not as like a PC. you can not create test 
scenerios for this type of testing and cannot write test 
cases for this.

Hemant is correct, you cannot create test cases for this 
type of testing in performance testing you cannot do 
scenerio based testing like you are performing for 
functional testing. sometime programmers are doing this 
testing using PERL scripting. Memory leackage bugs are 
generally occurs in C++ language only.
