What is ISuiteListener In TestNG

 ISuiteListener is another type of listener provided in TestNG this listener works on the suite level.

ISuiteListener listens to the event of the start of a suite execution and end of the suite execution. 

ISuiteListener runs the methods only before the start of the suite and at the end. It contains two methods:

• onStart: This method invokes before the test suite execution starts.

• onFinish: This method invokes after the test suite execution ends.

 

One should note that if the parent suite contains child suites then the child suites are executed before the parent suite.

Code example:

package isuiteListener;

import org.testng.ISuite;

import org.testng.ISuiteListener;

public class ListenersTest implements ISuiteListener{

@Override

public void onStart(ISuite suite) {

// TODO Auto-generated method stub

System.out.println("this is on start function  "+suite.getName());

}

@Override

public void onFinish(ISuite suite) {

// TODO Auto-generated method stub

System.out.println("this is on finish function "+suite.getName());

}

}
