Working with TestNG - Starters Guide

TestNG provides an option to shift to JUnit test, TestNG can automatically identify and execute Junit tests. User can execute already created JUnit test cases using TestNG.

Let's check this example to understand it better

Create JUnit Test Case Class:

package jUnit;

import org.junit.Test;

public class JunitDemo1 {

	@Test
	public void method1() {
		System.out.println("Welcome to JUnit");
	}
}

Create testing.xml file as shown below.

Note: Here we need define the property junit="true" in testing.xml file to execute the JUnit test cases as shown below.

<?xml version="1.0" encoding="UTF-8"?>
<suite name="Suite for conversion">
    <test name="JUnit test case" junit="true">
        <classes>
            <class name="jUnit.JunitDemo1"/>
        </classes>
    </test>
</suite>

Run the testing.xml file by click on run button in eclipse.

The Output is:

So you can see that its as simple as setting an additonal attribute junit="true" in test case element under testing.xml, which allows to testNG to make a switch over to JUnit automatically.
