Unit testing in Python is essential to ensure code reliability and promote a robust development process.

️ By systematically validating individual units of code, developers can identify bugs early in the development lifecycle, preventing them from turning into larger issues later.

Unit tests serve as a safety net, ensuring that code changes won't inadvertently break existing functionality.

They promote code maintainability by documenting expected behavior and serving as executable specifications for future reference.

With a comprehensive unit test suite, developers can iterate quickly, deploy with confidence, and deliver high-quality software that meets user expectations.
