An equivalence class is a subset of a value range from outputs or inputs for which a similar behavior of the component or system is assumed during testing. A value is representative for an equivalence class.
One of the test methods often employed in software testing involves equivalence classes. Simply put, system input is grouped into classes based on representative input domains.
Boundary value testing is a subtype of equivalence class testing and a common testing method for creating test cases. Boundary value testing is a testing method facilitated by our testing tool TPT.
Equivalence classes in the test case design are used to reasonably reduce the number of test cases. An equivalence class describes a value range. It is expected that that system under test reacts the same, no matter which value from that class you use as input. So it is common […]
