Equivalence partitioning is a black box testing technique that divides input data into equivalent classes and designs test cases to cover each class. It aims to test typical, boundary, and invalid cases to improve test coverage. The key steps are to identify the input range, divide it into logical partitions, and design test cases for typical values within each partition as well as boundary and invalid values. This technique helps reduce the number of test cases needed while still thoroughly testing an application's functionality across different input conditions.

Equivalence Partition
Hello! I am Swornim
1. What is Equivalence Partition?
“Equivalence partitioning/ Equivalence Class Partitioning 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 which, test cases are designed to cover each partition at least once.
Literally ▧ It is a Software test design technique similar to Boundary Value Analysis ▧ It is a black box technique* ▧ It can be applied to all levels of testing like unit, integration, system, etc.
Advantages 1. Saves time in testing. 2. Allows to fin more defects tha inputing random values to your code 3. It can be used in bot white box and black box testing
Equivalence Partition It is a Black Box Testing Technique that divides the input domain into classes of data from which test cases can be derived. Diffefence between Equivalence Partition and Boundary Value Analysis Boundary Value Analysis This is also a Black Box Testing Technique which concentrates on the Corner cases or the boundaries of the input domain rather than its center.
Equivalence Partition If we want to test a field which accepts values from 1 to 9, we will write test cases with the following test data. 1. Test case with test data less than 1 2. Test case with test data greater than 9 3. Test case with test data between 1 and 9 Diffefence between Equivalence Partition and Boundary Value Analysis Boundary Value Analysis If we want to test a field from 1 to 9 boundary values will be 0,1,2,and 8,9,10 The left hand value is called the lower boundary i.e 1 here in this example and the Right side value 9 is called the Upper boundary and hence the selection of values is a. Upper boundaries +1,-1 b. Lower boundaries +1,-1
How?? How is Equivalence Partitioning done ?
Process Input a Range Divide Input range to partitions Test each partition once
Invalid Partition 0 -1 -2 . . . Valid Partiton 1 2 . . . 31 Invalid Partition 32 33 . . . Date (1-31)
1. The range is divided. 2. The system picks one value from Invalid table and rejects it. 3. The system picks another value from Valid table and accept it. 4. The system picks a new value from invalid table and rejects it. 5. If one data is rejected the lot is rejected.
Which is !! Input range Divide into partitions Test each partition
