JUnit is an open-source, Java-based unit testing framework that plays a crucial role in achieving the culture of TDD (Test Driven Development). The TDD culture lays strong emphasis on setting up the test data for testing a logic that would be implemented once the testing is successful.
JUnit helps to increase the software stability as it helps in identifying the bug in the code logic at an early stage without requiring the software to go to production. This helps in reducing the time required to debug any issues later on.
JUnit is the testing framework, it is used for unit testing of Java code.
JUnit = Java + Unit Testing
