JUnit is a widely used open-source Java testing framework that enables developers to write and execute unit tests efficiently. It plays a key role in Test-Driven Development (TDD), where tests are written before implementing the actual code. JUnit offers features such as annotations, assertions, test runners, integration with build tools (such as Maven and Gradle), and support for parameterized testing.
