What is difference between Boundary Value Analysis and Equivalence Partitioning?

What is difference between Boundary Value Analysis and Equivalence Partitioning?

Boundary value analysis is testing the boundaries between partitions. It allows us to divide a set of test conditions into a partition that should be considered the same. The Equivalence partitioning will reduce the number of test cases to a finite list of testable test cases covering maximum possibilities.

What is Equivalence Partitioning and Boundary Value Analysis please explain with examples?

In Equivalence Partitioning, first, you divide a set of test condition into a partition that can be considered. In Boundary Value Analysis you then test boundaries between equivalence partitions. Appropriate for calculation-intensive applications with variables that represent physical quantities.

What are the guidelines for Equivalence Partitioning?

Guidelines for Equivalence Partitioning :

• If the range condition is given as an input, then one valid and two invalid equivalence classes are defined.
• If a specific value is given as input, then one valid and two invalid equivalence classes are defined.

What is Equivalence Partitioning with example?

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.

What is equivalence value?

Unlike Boundary Value Analysis, in Equivalence Class Partitioning, the input domain values are partitioned into equivalent classes. It validates at least one value from each partition. So, the test cases are designed to cover at least one set of data from each equivalent class.

How do you do Boundary Value Analysis?

Boundary Value Analysis (BVA) is a Black-Box testing technique used to check the errors at the boundaries of an input domain. The name comes from the Boundary, which means the limits of an area. So, BVA mainly focuses on testing both valid and invalid input parameters for a given range of a software component.

How are boundary value analysis and equivalence partitioning related?

Equivalence Partitioning and Boundary value analysis are linked to each other and can be used together at all levels of testing. Based on the edges of the equivalence classes, test cases can then be derived. Each boundary has a valid boundary value and an invalid boundary value.

How are boundaries tested in boundary value analysis?

Boundary Value Analysis- in Boundary Value Analysis, you test boundaries between equivalence partitions. In our earlier example instead of checking, one value for each partition you will check the values at the partitions like 0, 1, 10, 11 and so on.

How is equivalence partitioning used in the real world?

This technique is used to reduce an infinite number of test cases to a finite number, while ensuring that the selected test cases are still effective test cases which will cover all possible scenarios. Let’s take a very basic and simple example to understand the Equivalence Partitioning concept:

How is equivalence partitioning used in black box testing?

Equivalence Partitioning Equivalence Partitioning or Equivalence Class Partitioning is type of black box testing technique which can be applied to all levels of software testing like unit, integration, system, etc.
