Hi

Boundary value analysis is a software testing design technique in which tests are designed to include representatives of boundary values. The test cases are developed around the boundary conditions. One common example for this technique can be, if a text box (named username) supports 10 characters, then we can write test cases which contain 0,1, 5, 10, >10 characters.

Thought it may be useful
