## Boundary Value Analysis & Equivalence Partitioning with Examples - Shikshaglobe

Boundary Value Analysis (BVA) and Equivalence Partitioning (EP) are two closely related software testing techniques. BVA is a white box testing technique that is used to identify errors at the boundary of an application while EP is a black box testing technique used to divide the input data of an application into partitions.

BVA can be used to test both functional and non-functional aspects of an application while EP is primarily used to test functional aspects. BVA is typically used to test numeric fields date fields and drop-down menus while EP can be used to test any type of input field.

Both BVA and EP are powerful testing techniques that can help identify errors in an application. However, BVA is generally more effective at finding errors at the boundary of an application while EP is more effective at identifying errors in the functionality of an application.

Boundary value analysis and equivalence partitioning are two commonly used testing techniques. They are both used to create test cases based on the inputs and outputs of a system.

Boundary value analysis is a technique that is used to test the boundary conditions of a system. It involves testing the extreme values of input to see how the system responds. For example, if a system is designed to accept whole numbers between 1 and 10 boundary value analysis would involve testing with input values of 1 10 11 and -1.

Equivalence partitioning is a technique that is used to group together similar inputs and outputs. This means that if there are three possible inputs (1 2 and 3) then there would only need to be one test case for each input as they would all be treated the same by the system. For example, if a system is designed to accept whole numbers between 1 and 10 equivalence partitioning would involve testing with input values

Boundary value analysis (BVA) and equivalence partitioning are two important software testing techniques that can be used to test the functionality of a software application. BVA is a white box testing technique that is used to identify errors at the boundary of an application while equivalence partitioning is a black-box testing technique that is used to divide the input data of an application into partitions.

Both BVA and equivalence partitioning can be used to test the functionality of an application but they are different techniques. BVA is a white box testing technique that focuses on testing the boundaries of an application while equivalence partitioning is a black-box testing technique that focuses on dividing the input data of an application into partitions.

Both Boundary Value Analysis (BVA) and Equivalence Partitioning (EP) are used to test inputs to a system. The main difference between the two is that BVA test cases are designed around the edges of an input domain while EP test cases are designed around partitions of the input domain.

EP is usually faster and easier to carry out than BVA since it requires fewer test cases to be designed. However, BVA can sometimes uncover more errors since it tests inputs that are closer to the edge of the domain.

Here is an example of each technique:

Suppose we have a system that accepts student ID numbers. An ID number must be 9 digits long and can range from 100000000 to 999999999.

Using EP we would create 3 partitions:

- Partition 1: ID numbers ending in 0 (100000000 200000000 … 999990000)
