Black Box Testing – Equivalent Class Partitioning Explained

What is Equivalent Class Partitioning?

Equivalent Class Partitioning is a black box technique (code is not visible to tester) which can be applied to all levels of testing like unit, integration, system, etc. In this technique, you divide the set of test condition into a partition that can be considered the same.

• It divides the input data of software into different equivalence data classes.
• You can apply this technique, where there is a range in the input field.

In other words, It is used to minimize the number of possible test cases to an optimum level while maintains reasonable.
