Question { 22611 }

Explain the differences between White-box, Gray-box, and
Black-box testing.

Answer

White Box testing:In white box esting we check
coding,functional path,design nof the application.

Black Box testing:Inblack box testing there is no need to
know internal structure and coding of the appliction.

Gray Box testing:It si teh combiantion of both.Fo Gray box
testing we need to know programing language and intenal
structure of teh application also. In Gray box testing we
test the application from bot the side externally and
internally.

Question { Opus, 13743 }

Please let me know Whether testing comes under verification
or validation ?

Answer

verification and validation comes under testing,
verification is nothing but static testing and validation
means dynamic testing.So static testing comes under
verification while dynamic testing comes under
Validation.It would be wrong to say that testing comes
under verification or validation.

Question { 7699 }

we have develop one program i.e palindrome for string
character to check whether that string is palindrome or not.
example palindrome mean if u type ABCDCBA,RAAR..u can read
it form start or u can read it from end u find same string...
write the test cases for the above what u wil do for edges
boundaries check wether the program is correct or not

Answer

1)prerquisite:String should be minimum length 3.
2)The position of each character of string should be same
from both the side left and right.

eg:for the string ABCDCBA From left the position of A,B,C,D
is same as from the right.

Question { Accenture, 14390 }

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.

Answer

Hi preeti, the given scenario is not a valid scenario.I am
explaining you in deatil.The Grade respective to the score
will not valiadte.It will be like this

1)90-100---A
2)80-89----B
3)70-79----C
4)Else-----F

OR it can be 91-100----A
81-90-----B
70-80-----C
Else---F
And the boundary value analysis for this Object(0-100)
1)Min(0)-----Pass(0)F Grade
2)Max(100)---Pass(100)A Grade
3)min(+1)----Pass(1)F Grade
4)Max(-1)----Pass(99)A Grade
5)Min(-1)----Fail(-1)F Grade
6)Max(+1)----Fail(101)F Grade

for each validation user should have to write 6 test cases
Total validation above mentined 4 condtions so, (4*6)=24
test cases will occur.
For example considering first case:90-100(for grade A)

1)Min(90)-----Pass(90)A Grade
2)Max(100)--- Pass(100)A Grade
3)min(+1)---- Pass(91)A Grade
4)Max(+1)---- Fail(101)F Grade
5)Min(-1)---- Fail(89)B Grade
6)Max(-1)---- Pass(99)A Grade

Answer

yaa qestion was tricky,as u r saying we can check
functionality its fine we can apply BVA for Text box but
here system will fail at the value 80 and 90.For this
scenario atleast two bug will definetly occure at the value
80 and 90.
