Boundary value analysis and Equivalent partitioning

Question

difference between BVA and ECP in software testing

Blackbarbie Bb · Answer

Equavalece class partion: Equvalence partion is a black box testing method.Divides input domain of a program into classes of data from which testcases can be derived. In Equavalence partioning a test case designed as to uncover group of class of errors. Here the input domain is divided into classes groups data. These classes are known as equvalence classthe process of making these equvalence classes is known as equvalence class partion. Equavalence class partion represents a set of valid and invalid states of every input conditons Boundary value Analaysis: It has been observer that Program that work correctly for a set of values.In an Equavalece class fail on some special values These values often lie on boundary of equavalece class. BVA testcases are extreme test cases.
