Boundary value analysis is a testing technique that focuses on testing the boundaries of input values.

• It involves testing values at the upper and lower limits of valid input ranges

• It also tests values just outside of those ranges

• For example, if a system accepts values between 1 and 100, boundary value analysis would test values like 0, 1, 2, 99, 100, and 101
