What is unit testing?
Unit testing is a software testing technique where individual components or units of a software application are tested in isolation to ensure they perform as expected. It involves testing each unit of the code independently to verify its functionality, typically using automated testing frameworks. The goal is to identify and fix bugs early in the development process and to ensure that each unit works correctly on its own before integrating it into the larger system.
Unit Testing – Software Testing
Unit Testing is a fundamental aspect of software testing where individual components or functions of a software application are tested in isolation. This method ensures that each unit of the software performs as expected. By focusing on small, manageable parts of the application, unit testing helps identify and fix bugs early in the development process, significantly improving code quality and reliability.
Unit tests are typically automated and written by developers using various frameworks such as JUnit, NUnit, or pytest. These tests validate the correctness of code by checking that each function or method returns the expected results given specific inputs.
