Software test Method-Boundary value analysis method

Boundary Value Analysis Method:

In the test technology, the boundary value analysis method and the Equal price class division method have this agreement important position, the degree of frequent use of the test work is basically consistent with the Equivalence class division method, each use of the Equivalence class division method should be corresponding to the use of boundary value analysis method, the combination of two methods in-depth understanding, and flexible use is also the basis of software testing work

The boundary value analysis method is a black box test method to test the boundary values of input and output. The boundary value analysis is usually supplemented by the equivalence class partitioning method, in which case the test case is derived from the boundary value of the equivalence class.

Examples of equivalence class partitioning methods include:

1, the requirements of the software required when the total amount of product shopping cart shopping in [200,300], Shopping cart products enjoy 90 percent discount

Then the use case of the boundary Value Division method is 200,300, which is an effective complement to the equivalence class partitioning method.
