What is a core function of a Unit Test Framework?

A core function of a Unit Test Framework is to validate individual components of the software. Unit testing involves testing the smallest parts of an application, often individual functions or methods, to ensure they work as intended. This helps developers identify and fix bugs early in the development process, leading to more reliable code and simpler debugging.

The framework provides the necessary tools and methods to create, execute, and report on these tests. It typically includes assertions to check expected outcomes against actual results, making it easier to pinpoint issues.

This focus on validating individual components supports the principle of modular programming, where each piece of the application is designed to perform its specific function correctly. By ensuring that each unit is functioning properly, developers can have greater confidence in the overall behavior and quality of the software as it integrates with other components.

In contrast, integrating different modules or performing load testing are activities that occur later in the software development life cycle. Similarly, ensuring security measures is a broader concern that encompasses various testing types beyond unit tests, reflecting the importance of different testing strategies at different stages of development.
