Description: A unit testing framework is a set of tools and libraries that helps developers efficiently and systematically create and execute unit tests. These tests are fundamental in software development as they verify that each unit of code, such as functions or methods, behaves as expected. A unit testing framework provides a range of functionalities, such as organizing tests, automatically executing them, and generating reports on the results. Additionally, it facilitates error identification and validation of code changes, which is essential during the refactoring process. Refactoring involves modifying existing code to improve its structure and readability without altering its functionality. In this context, a unit testing framework becomes an invaluable tool, allowing developers to make changes confidently, knowing they can quickly verify if their code continues to work correctly. In summary, a unit testing framework not only improves software quality but also optimizes the development workflow, promoting cleaner and more sustainable coding practices.
