Daily Term: Unit Testing

Unit Testing

Unit Testing involves testing individual components or functions of code in isolation to ensure they work as expected. For example, a Python developer might use the unittest framework to test a function that calculates tax rates, mocking dependencies like database calls. Unit tests catch bugs early, improve code quality, and support refactoring, but they require writing and maintaining test cases, and they don’t catch integration issues.
