How to Implement TestNG listeners in Selenium Webdriver

[@ragus7609]

You are helping so many people for their jobs with your videos. Never stop sharing knowledge.

[@piyushraj8495]

Hi Mukesh, Thanks for the great teaching. :) For learners:- some time implements method will not show up. go to listeners, right-click go-to the source and select override implements method. I face this so thought of sharing this.

[@Mukeshotwani]

Thanks for the tips! Piyush

[@pramodkumarmohapatra9152]

Thanks @Mukesh otwani for the informative video. Also thanks Piyush for the tip. I was not seeing the methods initially. Then as per your comment, navigated to Listener class( e.g. TestNGListerner as per above video) and Right clicked>>Source>>Override/Implement Methods>>selected the required methods >> clicked OK. Finally all the required methods are visible in the class.

[@muzisadventure7660]

Hi Mukesh, thanks for your vedios. I have learned a lot from you. I am not getting quick fixes to implement the method of ITestListner in class. Plz help

[@nitingupta82]

Another Gem of a Video! Thanks! We can also implement EventFiringWebDriver and extend AbstractWebDriverEventListener in a separate class similar to the case mentioned above. Moreover there are a few shortcuts that comes handy: "// TODO Auto-generated method stub" can be removed by simply using 'Ctrl + d' on the specified line PLUS we can import all the drivers, jars and TestNG annotation drivers by simply pressing 'Ctrl + Shift + O'.

[@Mukeshotwani]

+Nitin Gupta Hi Nitin thanks for shortcuts. EventFiringWebDriver and AbstractWebDriverEventListener called as WebDriver listener which can also be implemented separately :)

[@nitingupta82]

But are they same or are separate things? Webdriver listeners and TestNG listeners.

[@akashdeep6355]

excellent work Mukesh

[@rameshrongala6359]

very nice explanation..mukesh garu.thanks

[@Mukeshotwani]

Thanks Ramesh :) I hope you will implement this feature in your project.

[@snehaldeshmukh7362]

Hi Mukesh, your videos are very good and easy to understand. When are you going to post next Listener video??

[@youvideo983]

Hi Mukesh, when u run the verify script, the same is giving some log4j entries. you said in the video that those are coming because, we have specified the same in the listener class. but I don't see where we have specified to get log4j entries. Can you please show the same or explain how to add in the listener class?

[@basweshwaramlapure8807]

Thank you Mukesh, can you please explain one report listener..

[@preetk4690]

hi mukesh i import the Itestlistener but i didnt got the add unimplemented method why it so

Hi Mukesh , Your videos are great help to me , where I can find the next videos on listener . Thanks in advance

[@neetigoyal9075]

hi Mukesh , one silly question here...here in listeners we see there is one argument ITestResult , what exactly is that.It is not any predefined data type or string.So what exactly it is ?? from where it came

[@Mukeshotwani]

Hi Neeti, ITestResult is interface of TestNG which store the result of Test which we execute and using ITestResult method we can capture our test details like status, time etc www.javadoc.io/doc/org.testng/testng/6.8.21/org/testng/ITestResult.html

[@CoolGuy-ez8lj]

Hi Mukesh, I have a query its possible to implement retryanalyzer inside ITest Listener. If so can you please share the sample program or video

[@Mukeshotwani]

Hi Mate, What is your actual requirement?

[@CoolGuy-ez8lj]

I see your videos for listener and retryanalyzers seperately and running the failed cases using separate class. Can you implement retryanalyzer interface method in the itestlistner interface failed test cases method so that once any test cases fail retryanalyzer will take care the retry logic. I am in learning phase so i dont have any exact project scenario. Just to know the things I am checking with you

[@AbhishekMishra-ru2fi]

Hi Mukesh , Need a help please. I am getting error: Listener ListenersDemo.MyFirstTestCase@2d363fb3 must be one of ITestListener, ISuiteListener, IReporter, IAnnotationTransformer, IMethodInterceptor or IInvokedMethodListener When I tried through XML. Please suggest.

Hi Mukhesh it's very useful and superb understandable. thanking you. can we save this report to excel ?

[@manikandankm3974]

Hi Mukesh, Can we give the Listener in the XML file as well ? Like

[@Mukeshotwani]

Hi Mani, both ways are correct, I have only covered class level but xml approach would be applicable for all classes in TestNG file.

[@cebisilemabaso8445]

Hi It does not give me an option to import ITestListener. Could you please help?

[@wertyzxc1]

Hi Mukesh, Firstly, a big thank you for all the wonderful videos you are posting. I have a question: In the listener class which implements the ITestListener interface, you have provided body for only few overridden methods, others you have not. Is it the right way? because, when any class implements an Interface you should either provide method body for all the methods that it inherited from the interface or mark the class itself as Abstract. How will the Listener class work in your example, because you provided method body for only few methods?

[@anjudogra3532]

super video sir.. thanks alot.

[@Mukeshotwani]

Welcome Anju

[@arkaimps]

Hi Mukesh... Thanks for the short sweet and detailed explanations... Can you please suggest that if a project is using ExtentReport Listeners then we require TestNg listeners separately? ExtentReport also internally uses TestNG only. Which are the cases that is advantageous to use TestNG listeners or ExtentReport Listeners?

[@Mukeshotwani]

Hi Nag ExtentReport Listeners is enough no need to add TestNg listeners

[@arkaimps]

Thanks Mukesh... Sometimes it gets very confusing when there are so many paths to go to the Destinations.. :)

With implementation as explained by you, my code is running twice and result.gettestname() is displaying value as null. Pls explain .On debugging I found that once it went to onTeststartmethod() and then went to TestListenerHelper.class and then came back to onTeststartmethod() resulting into display of text message twice.

me too how can i get ?

[@MyCoolestboy]

Class not found error is coming while executing MyFirstTestCase

[@rdntech2738]

Awesome explanation. Thanks Mukesh. In my application, there is an unexpected popup that shows up on any screen which makes the test case fail. I can surround findelement with try-catch for most likely cases but it may happen on any screen so this is not a good idea to cover every findelement statement with try-catch. I would like to have a mechanism in which if findelement fails at any place due to an unexpected pop up, it will go for handling exception( or handle pop up etc) and then re-execute the same find element statement one more time and return back to test execution to continue future steps. After some research on Internet, I feel it might be done using WebDriverEventListener. Can you please suggest, how this can be achieved? I am using Java Selenium TestNG.

[@PraveenTata16]

To take a screenshot using ITestListener when a test fails we can use this : private WebDriver driver; public void onTestFailure(ITestResult result) { // since you need the driver in your screenshot method do this: this.driver = ((TestBaseClass)result.getInstance()).driver; // here comes your screenshot method // ... } more details here : stackoverflow.com/questions/32476390/take-screen-shot-using-listeners

[@Mukeshotwani]

+Praveen Tata thanks Praveen

[@doyouknow8331]

Can we use these listeners in XSLT reports customization ?

[@ramniwasverma9853]

Nice Video Sir. One question - If a line of code is failing in a method (test case) and we have more lines of code after failing line which will not be executed in this case, but we want those lines to be executed and also want to mark the test case as failed, how can this be achieved ? I hope I am clear enough with my question. i.e. I want to print the message "Print this message after failing the test case.": @Listeners(myPackage.ListenersClass.class) public class CallListeners { @Test public void testListener(){ Assert.assertTrue(false); System.out.println("Print this message after failing the test case."); } }

[@ramniwasverma9853]

Sir, did you get a chance to have a look at above ?

Hi guys, I think result.getMethod().getMethodName()); will work instead of just result.getMethod();. I tried it. Apart from this, when i trying using the xml file, I am getting the listeneers statements twice. E.g.: TestCase started and TestCase details are GoogleTitleVerify TestCase started and TestCase details are GoogleTitleVerify Google TestCase success and TestCase details are GoogleTitleVerify TestCase success and TestCase details are GoogleTitleVerify Any particular reason behind this ?
