Boundary Value Analysis

Boundary Value Analysis (BVA) is a testing technique used in various fields, including software development, to identify errors at the edges of input ranges. Instead of testing only typical values, BVA focuses on the extreme limits, such as minimum and maximum values, as well as values just inside and outside these limits. For example, if a system accepts numbers from 1 to 100, BVA would involve testing numbers like 1, 100, 0, and 101. This helps ensure that the system behaves correctly at critical points, reducing the risk of bugs or failures in real-world scenarios.
