Function Testing is testing the function of the product

Eg:Mobile
   It's main function is (1)to make a call 
                         (2)to receive a call
   Testing these 2 funcion of the mobile is called Function 
testing

Sumit,

Kindly explain the non functional testing in the same 
regard, can you?

I am seriously looking for non functional testing example 
not wild guess, hope you understand.

HI,
Smit here
In the Above example I explain Functional ex.

Eg:Mobile
   It's main function is (1)to make a call 
                         (2)to receive a call

   Non-Functional is (1) It's Colour, look & feel feature
                     etc

Non Functional testing for the above would be stress 
testing etc..
