How to do the Equivalence Partitioning ?

If a field to be tested accept the range of value the test it for on valid and two invalid data . for details understanding check the below example 

Example on Equivalence Partitioning Test Case Design Technique

Example : Below the student register page given which consist of field like name , class, mobile, age etc. We have to test the age field which accept age between(18-35) .By applying Equivalence Partitioning technique .

Equivalence Partitioning testing example

Here , 

Valid -18 

Invalid -17

Invalid- 36

Here we have applied on valid and two invalid conditions .

• Age between 18 to 35 considered as the valid age.System should accept the age .
• Age less than 18 ie.17 and more than 35 ie.36 is invalid age ,system should display alert message . 

Hope !!! The above tutorial of Equivalence class Partitioning helpful for you...
