If you use / implement any listener in your class / project, then add the @Listeners annotation for this class, like @Listeners below:
@Listeners(value=SuiteListener.class)
eg
@Listeners(value=ClassName who implemets listener.class)
eg
@Listeners(value=SuiteListener.class) public class SuiteListener implements ISuiteListener { lines of code / methods in class }
Add below code snippet to testng.xml
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd"> <suite name="Suite"> <listeners> <listener class-name="report.SuiteListener"></listener> </listeners> <test thread-count="5" name="Test"> <classes> <class name="tests.Test1"/> <class name="tests.Test2"/> </classes> </test> </suite>
