   Equivalence Partitioning 
The main objective of this method is to partitioning the input so that an optimal input data is selected. 

Steps to be followed are:

1. Divide the input domain into classes of data for which test cases can be generated.
2. Attempting to uncover classes of errors, if any.
3. Identify the both right and wrong input data while partitioning the data.
4. Test the program for all types of data. 

Based on equivalence classes for input conditions.
An equivalence class represents a set of valid or invalid states
An input condition is either a specific numeric value, range of values, a set of related values, or a boolean condition.

•   If an input condition specifies a range or a specific value, one valid and two invalid equivalence classes defined. 
•   If an input condition specifies a boolean or a member of a set, one valid and one invalid equivalence classes defined. 
Test cases for each input domain data item developed and executed.
This
method uses less number of input data compare to exhaustive testing.
However, the data for boundary values are not considered.
This
method though reduces significantly the number of input data to be
tested, it does not test the combinations of the input data.
