Q1. What is BVA Testing?
Ans. 
BVA Testing stands for Boundary Value Analysis Testing, a software testing technique to test the boundary values of input ranges.
• BVA Testing is used to identify errors at the boundaries of input ranges.

• It involves testing the minimum and maximum values, as well as just inside and just outside the boundaries.

• For example, if a system accepts values from 1 to 10, BVA Testing would test values 0, 1, 10, and 11.
