import org.testng.annotations.Test;
public class TestNGExample{
@Test
Public void TestNGSample(){
System.out.println(“This is my Frist TestNG programme”)
}

How to Generate TestNG XML file

Make sure that TestNG jar files should be associated to your project
Right-click on the your project(TestNGExample)and select TestNG | Convert to TestNG.

Then click on Next button then Finish Button
Sample TestNG.xml file
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Suite" parallel="none">
<test name="Test">
<classes>
<class name="TestNGExample"/>
</classes>
</test><!-- Test -->
</suite><!-- Suite -->
Now you need to run test through this testng.xml.
