Answer:
a) To test individual components or functions of the software
Explanation:
Unit testing focuses on testing individual components or functions of the software in isolation from the rest of the system. The goal is to ensure that each component works as intended and meets its specified requirements.
Unit tests are typically written by developers and are automated to provide quick feedback during the development process. They are essential for catching bugs early and ensuring that changes to the codebase do not break existing functionality.
Unit testing is a critical part of the software development process, helping improve code quality and maintainability.
