Take username field as example that have req for entering 5

BVA for this is

min = 5
min+1 = 6 pass
min -1= 4 fail
max = 15 pass
max+1 = 16 fail
max-1 = 14 pass


EVP for this is

Check values like
any value <5 characters
between 5 to 15 characters
any value > 15 characters

BVA and EVP covers all possible scenarios to find bug in the
