Detailed explanation-1: -Note that there are two types of equivalence classes: valid equivalence classes representing valid input data of the program; invalid equivalence classes representing all other possible condition states (i.e. invalid input values).

Detailed explanation-2: -Equivalence partitioning or equivalence class partitioning (ECP) is a software testing technique that divides the input data of a software unit into partitions of equivalent data from which test cases can be derived. In principle, test cases are designed to cover each partition at least once.

Detailed explanation-3: -Examples of Equivalence Partitioning technique For example, an OTP number which contains only six digits, less or more than six digits will not be accepted, and the application will redirect the user to the error page. Let’s see one more example. A function of the software application accepts a 10 digit mobile number.
