Setting up Java JUnit Project with Eclipse + Maven Example

1. In Eclipse, go to File -> New -> Other...
2. Now Select Maven -> Maven Project
3. Click Next,
4. Select "Create a simple project (Skip archetype selection)", Next
5. Enter Group Id and Artifact Id and click Finish.
6. Now open the pom.xml and add the following dependency for Junit 4 under dependencies,

   	<dependencies>
   		<dependency>
   			<groupId>junit</groupId>
   			<artifactId>junit</artifactId>
   			<version>4.8.1</version>
   			<scope>test</scope>
   		</dependency>
   	</dependencies>

7. Create a java file,

   package myprog;
   
   public class Addition {
   	
   	public int add (int no1, int no2) {
   		return no1 + no2;
   	}
   }
   

8. Now write a text class for the class we created under src/test/java package,

   package myprog;
   
   import static org.junit.Assert.assertEquals;
   
   import org.junit.Test;
   
   public class AdditionTest  {
   
   	@Test
   	public void addTwoNumbers() {
   		Addition addition = new Addition();
   		assertEquals(5, addition.add(2, 3));
   	}
   	
   }

Now let's run the maven test command to run the test cases, simply right click on your project folder and select Run As -> Maven test
