can u pls explain me what is boundary value analasys and equivalent partitioning..

u have to define 4 cases 2 for valid class & 2 for invalid
class, like if u have user name max 6 char for that u have
to enter 1.Blank 2.one char 3.six char. 4.seven char that is
boundary value analysis.

Answer / durga prasad

Boundary value analasys:
Let the upper limit and Lower limits be N and M for a
system then
N-1, N , N+1 , M-1, M and M+1are considered as inputs for
Boundary value

Equivalent partitioning :
When N amd M are lower and upper limits of a system the
Equivalent partitioning includes "N. M and any input
between "N and M".

Boundary Analysis- This is a black box test design tech. In
boundry analysis tester will test the software at tha edges
of the equivalence partition. Idea is to assume if software
work perfectly at the edges it will work properly else
where. e.g. if a text field accepts value between 0-100
boundry value test should include values as lower limit-1
i.e. -1 & valid value anything between 0 to 100 & Upper
limit +1. Boundry value analysis is used to reduce the
redundancy in test cases.

Equivalence Partition- This is a blk box test design tech.
in which the whole input domain is divided in to few no of
logical partitions. These logical partitions are termed as
Equivalence Partitions. It is assumed that all values in a
partition are supposed to have same system responce.
e.g. if a text field accepts value between 0-100 then
according to eqv Partition less than 0 is one partition, 0-
100 will be second partition & more than 100 will be third
partition. Equivalence partitioning is used to reduce the
redundancy in test cases.

Answer / gautam

in above answer use 2 & 4 for BVA
& for equivalence use all 1 to 4 step.
