What is the primary purpose of a test case?

The primary purpose of a test case is to provide a step-by-step procedure for executing tests. This structured approach allows testers to systematically verify that a component or system behaves as expected under specific conditions. Each test case typically includes the inputs, execution steps, expected results, and actual results, which ensures that testing is consistent and repeatable.

By following the detailed instructions outlined in a test case, testers can efficiently execute tests, track results, and identify discrepancies between expected and actual outcomes. This precise definition of actions and expected results enables effective assessment of the software's functionality and quality. Furthermore, well-defined test cases contribute to better coverage of requirements and functionalities, facilitating a comprehensive evaluation of the software's performance.

In this context, while other options present valuable aspects related to testing, they do not encapsulate the primary purpose of a test case. Test cases are primarily centered around the execution process, making them crucial for validating software functionality.
