Explain Equivalence Class Partitioning
Equivalence Class Partitioning: It is a method in black box testing. It is designed to decrease the number of test cases by dividing tests in such a way that the system is expected to act the similar way for all tests of every equivalence partition. Test inputs are selected from every class. Each possible input belongs to one and only one equivalence partition." In another words it is a method that can help you derive test cases. You recognize classes of input or output conditions
