What is Boundary Value Analysis(BVA) and Equivalence Class
Partition(ECP)?

Answer Posted / sunitha

BVA: Instead of we entering every possible input domain we
check the input domains with boundaries only.

Eg:empID takes 4-16 alphabets.

value - status.

min->4 pass
min-1->3 fail
min+1->5 pass
max->16 pass
max-1->15 pass
max+1->17 fail.

ECP:
with this we enter valid values enter as input domains.

Eg:
empID should accept 4-16 alphabets.

valid - invalid

a-z 0-9
A-Z spaces, special characters.
