Write an automation test case using TestNG.

Create a java project using maven in the eclipse and create a TestNG. Let’s follow some basic steps to run your first automation test case using TestNG.

Step 1) Create a Simple Java or Maven Project in Eclipse.

Step 2) Create a TestNG class. In My Case, I create a class with the name “TestCase1” under the “Testcase” package.

Step 3) Observe the autogenerated code in the class. Did you notice there is some error? Don’t worry we are just missing a jar file for TestNG.

Step 4) Add TestNG jar into the project.

If you are working with maven then open the “pom.xml”, Add the dependency for TestNG and save it. To find the latest version of TestNG just Google “Maven dependency for TestNG”.

If you are using a simple java project then you have to download TestNG jar and manually need to import it in the project library.

Step 5) Write the first TestNG Program.

package testcase;

import org.testng.annotations.Test;

public class TestCase1 {

public void f() {

System.out.println("This is my first TestNG program");


Step 6) Run the TestNG class.

Could not find

While you trying the above manual steps to install TestNG in eclipse might be you get this error. so let’s discuss some common ways to resolve this.

Check Network connection of eclipse

Check your internet connection and make sure it’s working and connect with your machine. Also, make sure the same connection is configured into the eclipse network connection. Windows -> Preferences -> General -> Network Connections, make sure you have correct settings.

If you using a private network of an organization or company then disconnect from this network and connect to your network (Like mobile hotspot or home wifi). Try install then. this is my personal experience.

Upgrade eclipse version

make sure, you are using the updated version of IDE, Eclipse, or STS. so go to the official website of the eclipse and verify the version that you have at your machine. keep it up to date.
