Boundary Testing

Boundary Testing is the most used kind of test design that should help a tester to choose the most effective meanings for testing. This kind of testing can be applied at any testing level such as unit, integration, system, and system-integration test levels. Here are the main steps of the data testing analysis: one should define the range and range boundaries, for every boundary one should create 3 test cases, the first one should check the boundaries itself, the second one should check the meaning below the boundary and the third one should check the meaning above the boundary.
