BAV : Testing at the Edge of Inputs
Boundary Value Analysis: Boundary value analysis is a black box testing techniques its used to validate the input values at their boundary limits. This BAV technique is used to identified the errors at the boundary conditions. In BAV, tester need to identify the input boundaries to determine the minimum and maximum acceptable values for each input field.To design the test cases tester need to follow the below criteria, 1.Minimum boundary value. 2.Above the minimum value. 3.Below the maximum value. 4.Maximum boundary value. 5.Above the invalid maximum value. 6.Below the invalid minimum value. If tester will prepare the test cases in above criteria and run the each test cases will confirm the applications handles the boundaries correctly. Benefits of boundary values are tester can effectively identified the bugs which was commonly missed by other validation techniques, especially boundary cases.Also BAV will helps to reduces the test effort by concentrating high risk values. In BAV, tester can targets the edges of input where the defects are more likely to the surface.Also it includes minimum and maximum input values just inside and outside of boundaries.In BAV technique testers don't need knowledge of the software about internal logic and source code.
