Testing - What is Equivalence Partitioning?

What is Equivalence Partitioning?

- The division of domain data into different equivalence data classes is performed using Equivalence Partitioning. It is implemented for reducing the number of test cases to finite set of testable test cases, by covering the maximum requirements.

- Equivalence partitioning is a technique used in software testing which aims to reduce the number of test cases and choose the right test cases. This is achieved by identifying the “classes” or “groups” of inputs in such a way that each input value under this class will give the same result.

E.g. a software application designed for an airline has special offer functionality. The offer is that first two member of every city booking the ticket for a particular route gets a discount. Here, the group of inputs can be “All cities in India”.
