If an integer input field accepts values between 10 and 100 inclusive, the critical boundary values for Boundary Value Analysis (BVA) are:
A10, 50, 100
B0, 10, 100, 1000
C9, 10, 100, 101
D5, 15, 95, 105
Explanation
Two-value BVA tests the exact boundary values and their immediate outer neighbors ($10-1=9$, $10$, $100$, $100+1=101$).
