what is the difference between BVA&ECP?
Answer Posted / naresh
These two menthods are useful to minimize the test cases.
These two methods are looking very simillar
In BVA(Boundary Value Analysis) we can check the the
boundaries values min-1, min, middle value(optional), max,
max+1
For example: If the boundary value for a field is between 1
to 98 , we can check with the values 0,1, any of the value
between 1 to 98 , 98 and 99
please let me know if i'm not correct
but in Equivalece Class Partioning we should check the
condition with different values from three partitions like
we should take some values in the positive partition and
take some values from negative partitions. For example take
the above example here the positive partition is the range
beteween 1 to 98, the negative partitions are o to -97 and
99 to 196.
see in the BVA we are not checking with the minus values
like -1, -2, -3 we can't say it can't take minus values and
also we are not checking with the three digit numbers in
the BVA, but here we have scope to check the three digit
values also as well
