TestNG - Plug with Eclipse

To set up TestNG with Eclipse, follow the steps given below −

Step 1: Download TestNG Archive

Download the latest version of TestNG jar file from http://www.testng.org

We assume you have copied the above JAR file in /work/testng folder.

Step 2: Set Eclipse environment

• Open eclipse → right click on the project and go to property → Build Path → Configure Build Path and add the testng-7.4.jar in the libraries using Add External Jar button.

• We assume that your Eclipse has inbuilt TestNG plug-in; if it is not available, then please get the latest version using the update site.

  • In your Eclipse IDE, select Help / Eclipse Marketplace.

  • Search for Testng. You will get the TestNG in the list. Click on Install as shown below:

    

Now, your Eclipse is ready for the development of TestNG test cases.

Step 3: Verify TestNG Installation in Eclipse

• Create a project TestNGProject in Eclipse at any location.

• Create a class MessageUtil to test in the project.

/*
* This class prints the given message on console.
*/

public class MessageUtil {

   private String message;

   //Constructor
   //@param message to be printed
   public MessageUtil(String message) {
      this.message = message;
   }

   // prints the message
   public String printMessage() {
      System.out.println(message);
      return message;
   }
}

• Create a test class TestNGExample in the project.

import org.testng.Assert;
import org.testng.annotations.Test;

public class TestNGExample {
   String message = "Hello World";
   MessageUtil messageUtil = new MessageUtil(message);

   @Test
   public void testPrintMessage() {
      Assert.assertEquals(message,messageUtil.printMessage());
   }
}

The project structure should be as follows −

Finally, verify the output of the program by right-clicking on the program and running as TestNG.

Verify the result.
