Listeners in TestNG

If you want to add logs into your test script you can use listeners. Listeners work on action so have below methods.

OnTestStart : Invoked each time before a test will be invoked.

OnTestSuccess : Invoked each time a test succeeds.

OnTestFailure : Invoked each time a test fails

OnTestSkipped : Invoked each time a test is skipped.

OnTestFinish

How to use in your current project

Create Class 'ListenersClass.java'

code like

package com.example.logging;

import org.testng.IClass;

import org.testng.ITestResult;

import org.testng.TestListenerAdapter;

public class ListenerClass extends TestListenerAdapter {

@Override

public void onTestStart(ITestResult tr) {

log("Test Started....");

}

@Override

public void onTestSuccess(ITestResult tr) {

log("Test '" + tr.getName() + "' PASSED");

Use the above class in your exiting main test class by importing above class.

Add listners in to testng.xml as well

listeners>

<listener class-name="Tru.XXX.logging.ListenerClass" />

</listeners>

Enjoy longing so that you can have better understanding where test fails.
