After building the test listener class, users can then include it at the test class level, or in the TestNG Suite XML file, as follows:

/**
 * My Test Class
 * 
 * @author Name
 * 
 */
@Listeners(TestNG_Listener.class)
public class MyTest {
    ...
}

// TestNG Suite XML File

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">

<suite name="My_Test_Suite" preserve-order="true" verbose="2">
    <!--  test listeners -->
    <listeners>
        <listener class-name="myPath.TestNG_Listener" />
    </listeners>
    ....

</suite>
