Explain Boundary value analysis, Equivalence partitoning
and Error guessing?
Answer / aa
Boundary value analysis : Designing test cases at boundary
values. If field take values from 10 to 20 numbers,
following are the boundary values which is taken care while
doing testing.
Valid boundary values 10, 11, 19, 20
Invalid Boundary values 9, 21.
Equivalence partitioning : Designing test cases by deviding
the input values in to equivalence partitions.
valid Equivalence partitions 14 or 18
Invalid equivalence partitions 5, 26
Error guessing : From testers experience , are able to guess
where bug will come and in which scenario.

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
