JUnit is a widely adopted testing framework for Java that enhances test-driven development by facilitating unit testing. It simplifies the process of writing tests with its built-in annotations and assertions, and provides a structure for organizing tests into suites. JUnit also supports regression testing and offers flexible options for executing test cases in a controlled environment.
