Boundary value analysis method checks the boundary values of Equivalence class partitions. Boundary value analysis is basically a testing technique which IDENTIFIES the errors at the boundaries rather than WITHIN the range values.

For Example: An input field can allow a minimum of 8 characters and maximum 12 characters then 8-12 is CONSIDERED as the valid range and 13 are considered as the invalid range. Accordingly, the test cases are written for valid partition value, EXACT boundary value, and invalid partition value.
