Equivalence Partitioning - (Testing Techniques)

Equivalence Partitioning is a popular testing technique that allows you to break down the inputs to your system into groups that have similar behavior. In this tutorial, we'll discuss how to use Equivalence Partitioning to improve your software testing.

Syntax

There is no specific syntax for Equivalence Partitioning.

Example

Suppose you have a form that requires users to enter their age. The valid age range is between 18 and 65. Using Equivalence Partitioning, you can break down the possible input values into three groups:

• Age values less than 18 (Invalid)
• Age values between 18 and 65 (Valid)
• Age values greater than 65 (Invalid)

You can then design test cases to cover each group, ensuring that the form handles each case appropriately.

Explanation

Equivalence Partitioning is a black box testing technique that allows you to partition the possible input values into groups that are likely to have similar behavior. By testing one value from each group, you can ensure that the system handles all of the values in that group correctly.

Use

Equivalence Partitioning is a useful technique for testing systems that have a large number of possible input values. Some common scenarios where Equivalence Partitioning can be useful include:

• Input fields that have specific ranges or validation rules
• Applications that deal with large amounts of data
• Systems that interact with external APIs

Important Points

Here are some important points to keep in mind when using Equivalence Partitioning:

• Be sure to consider all possible input values when breaking them down into groups.
• Test one value from each group to validate that the system behaves correctly for all values in that group.
• When possible, use automated testing to cover all possible input values.
• Consider combining Equivalence Partitioning with other testing techniques, such as Boundary Value Analysis, to ensure full coverage.

Summary

In this tutorial, we discussed Equivalence Partitioning as a testing technique to improve the quality of software testing. We covered examples, explanation, use, and important points of using Equivalence Partitioning. By applying Equivalence Partitioning in your testing, you can ensure that your testing is thorough and covers all possible input values.
