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 www.testng.org. http://www.testng.org

OS	Archive name
Windows	testng-6.8.jar
Linux	testng-6.8.jar
Mac	testng-6.8.jar

We assume you have copied the above JAR file in C:\>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-6.8.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 / Software updates / Find and Install.
  • Search for new features to install.
  • New remote site.
  • For Eclipse 3.4 and above, enter http://beust.com/eclipse.
  • For Eclipse 3.3 and below, enter http://beust.com/eclipse1.
  • Make sure the check box next to the URL is checked and click Next.
  • Eclipse will then guide you through the process.

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.
