What is Boundary Value Analysis(BVA) and Equivalence Class
Partition(ECP)?
Answer Posted / swapna
BVA & ECP are 2 mathematical notations which will be followed in BBT(input domine test'g),it,s a part of functional testing.
BVA: it helps to determine SIZE & RANGE(boundaries) of inputs.
ECP:it helps to determine VALID/INVALID cases of inputs.
Example: IN a login process,USername object allows alphabets & numarics from 4 to 20 characters long in both lower & upper cases. where as password object allows only alphabets from 4 to 10 characters long only in lower cases.
1)USER NAME:
BVA(Size/Range) ECP(Valid/invalid)
Min = 4 = pass Valid & invalid
Max = 20 = pass 0-9, A-Z blank spaces&special char's
MIN-1=3 = fail a-z
Max-1=19= pass
Min+1 = 5 = pass
Max+1 = 21 = fail
2)PASSWORD:
BVA(Size/Range) ECP(Valid/invalid)
Min = 4 = pass Valid & invalid
Max = 10 = pass a-z 0-9, A-Z
MIN-1=3 = fail blank spaces&special char's
Max-1=9= pass
Min+1 = 5 = pass
Max+1 = 11 = fail
