Answer / vinay
White box testing is done to check the right coding and
internal coded loops and modules working properly or not but
Black box testing is must after white box because in black
box we give the input and check the expected output and also
check system compatibility which is the main requirement of
the software.

Answer / dwarika dhish mishra
Blackbox means opaque object, It means we never go in to internal structure of the product. Black box testing is done to test the functionality of product without going to internal structure.
Through Black box testing we find out the bugs related to UI, Usability, Functionality. but by using black box testing we can't find out bugs related to Memory leak, Logical error.

Hi All, I am new in testing field. I got an interview and the question was asked- What would be your high level test case on the following scenario. There are 2 fields one is SCORE and other is GRADE and there is a go button. Scenario is If score is 90- 100 then grade should be A, if Score is 80-90 then B, if 70- 80 then C Else F. So I told that - I will check Boundary values by giving max +1 and min-1 values. I will check the functionality is working as per the requirement or not. I will include + and - testing. But seems like my answer was not correct, obviously because I don't have much experience. So plz provide me the best answer of this Q ? Thanks in advance. Preeti
