hi.

Positive test cases: ordinary calculations ie, 2+2,4*4,5/5.
result should be correct and acceptable.

Negative test cases:
1. 5/0
2. 0/0
3.pressing more than one button at a time should not
work.

Hey thanx Merlin ! I got the answer but again you have to be very specific regarding the test cases.
like
in case of 2+2
Precondition is : Textfield should display "0. and not "0"
When you presss 2 expected result should be "2." and not "2"
hope you got it.
Thnx for replyn the thread ....Catch u some other time
