What outcome is expected from implementing boundary value testing?

Implementing boundary value testing is focused on identifying potential defects that are most likely to occur at the edges of input ranges. This method stems from the principle that errors often appear at the boundaries of acceptable input values rather than in the middle of input ranges. By systematically testing values at, just below, and just above these boundary conditions, testers can uncover issues that may not be detected through regular testing methods.

For instance, if a function accepts input values ranging from 1 to 100, boundary value testing would involve testing the values 1, 100, 0, and 101. These tests specifically target the limits and help ensure that the system behaves correctly at these critical points. Therefore, the outcome from boundary value testing is effectively finding defects that tend to cluster near the input limits.
