What is the difference between testing and JUnit?
JUnit is a unit testing framework for the Java programming language. It is used by the developer to write tests that are independent of the actual implementation of their code and are meant to throw exceptions if they are not satisfied by the outcome of a certain function or method. The JUnit framework is a test runner, which means its main function is to run tests written in other programs.
In Comparison, Testing is the process of validating that your application works as expected and has no errors or defects. Unit testing is a type of software testing that focuses on testing individual units or groups of interacting units within an application. Unit tests are created to ensure that every part of an application works correctly, from the code it contains to how it interacts with other parts of the program or external services.
