Boundary value analysis

Boundary Value Analysis works well when the Program Under Test (PUT) is a "function of several independent variables that represent bounded physical quantities" [1]. When these conditions are met BVA works well but when they are not we can find deficiencies in the results.

Boundary value analysis. Jun 28, 2023 · Boundary Value Analysis (BVA) is a Black-Box testing technique used to check the errors at the boundaries of an input domain. The name comes from the Boundary, which means the limits of an area. So, BVA mainly focuses on testing both valid and invalid input parameters for a given range of a software component.
