JUnit is a widely used testing framework for Java applications. It is designed to facilitate the testing of Java code and is part of the xUnit family of testing frameworks.

Key Features

  • Test Annotations: JUnit provides a set of annotations to define test methods, test classes, and test suites.
  • Assertion Methods: It offers various assertion methods to verify the expected results.
  • Test Suites: JUnit allows you to group tests into suites for easier management and execution.

Getting Started

To get started with JUnit, you need to include the JUnit library in your project. You can download it from the official JUnit website or use a build tool like Maven or Gradle.

Example

Here's a simple example of a JUnit test:

import org.junit.Test;
import static org.junit.Assert.*;

public class ExampleTest {

    @Test
    public void testAdd() {
        assertEquals(5, 2 + 3);
    }
}
