This tutorial explains the use of JUnit in your project unit testing, while working with Java. After completing this tutorial you will gain sufficient knowledge in using JUnit testing framework from where you can take yourself to next levels.
What is JUnit ? JUnit is a unit testing framework for Java programming language. It plays a crucial role test-driven development, and is a family of unit testing frameworks collectively known as xUnit.
JUnit is a Regression Testing Framework used by developers to implement unit testing in Java, and accelerate programming speed and increase the quality of code.

These annotations in JUnit provide the following information about test methods − which methods are going to run before and after test methods. which methods run before and after all the methods, and. which methods or classes will be ignored during the execution. The following table provides a list of annotations and their meaning in JUnit −
Features of JUnit JUnit is an open source framework, which is used for writing and running tests. Provides annotations to identify test methods. Provides assertions for testing expected results. Provides test runners for running tests.
JUnit 4 has introduced a new feature called parameterized tests. Parameterized tests allow a developer to run the same test over and over again using different values. There are five steps that you need to follow to create a parameterized test.
Following table compares JUnit vs TestNG on different features. The table excludes very specific or common features that are present in both these frameworks, such as testing exceptions, timeout settings, lifecycle callback methods etc.
