Equivalence partitioning?

Question

What is equivalence partitioning?

Karina Cotton · Answer

Equivalence partitioning is a software testing approach that divides a program's input data into separate partitions, or equivalence classes. Equivalence partitioning is based on selecting representative input values from each partition in order to construct successful test cases. Using equivalence partitioning, testers can reduce the number of test cases Geometry Dash while maintaining acceptable test coverage. This technique allows you to evaluate the application using a manageable collection of test cases that represent various scenarios, rather than checking every conceivable input value.

Equivalence Partitioning - Testing Technique Equivalence Partitioning (EP) is a black-box testing method that categorizes input data into equivalence classes , minimizing the number of test cases while maintaining comprehensive test coverage. Key Concept Equivalence Partitioning In Testing Rather than testing every possible input, equivalence partitioning categorizes inputs into partitions (sets) where: All inputs within a partition are expected to yield the same outcome. A single test case from each partition is sufficient for validation. Advantages of Equivalence Partitioning Minimizes the number of test cases while maintaining defect detection. Provides comprehensive coverage of input scenarios. Enhances testing efficiency and effectiveness.

Equivalence partitioning is a software testing technique used to divide the input data of a program into different partitions, or equivalence classes. The idea behind equivalence partitioning is to select representative input values from each partition to design test cases effectively. By using equivalence partitioning, testers can reduce the number of test cases while still ensuring adequate test coverage. This technique allows for testing the application with a manageable set of test cases representing different scenarios, without the need to test every possible input value. For example, if a program accepts numeric input in the range of 1 to 100, you can divide this input into three equivalence classes: values less than 1, values between 1 and 100, and values greater than 100. Test cases can then be designed to cover these different ranges, such as testing with values like -1, 50, and 101. Equivalence partitioning helps in optimizing testing efforts by focusing on testing a sample of values within each equivalence class, rather than exhaustively testing every single input value. This method increases efficiency in testing and helps detect bugs and issues more effectively. In practice, equivalence partitioning is widely used in various software testing scenarios, ranging from unit testing to system testing, to ensure comprehensive test coverage without overwhelming the testing process with redundant or unnecessary test cases.
