Would you use listeners with Extent reporter? So if a test fails, you can say take a screenshot to add to the report?

[@RaghavPal]

Yes that is very much practiced Paul

[@nistan5404]

Hi Raghav, I m following all the steps as you mentioned in video but I m not getting any error to add the unimplemented methods...I also restarted eclipse...but issue remains same...my testNG version is "7.1.0". package Listeners; import org.testng.ITestListener; public class TestNGListeners implements ITestListener { }

[@nistan5404]

My issue is resolved now after using below steps: Right click(on the Listeners class from ProjectExplorer ) -> go to source-> click on overide/implement methods -> select the check boxes for the ITest listener (make sure all check box inside it should be checked )->click on oK. That's it !!! :)

Hello sir plz help to know which is the best certification for jmeter or make a video for which certification is good for fresher QA. Plz plz Sir

[@RaghavPal]

Abhinav, do not post the same comment on different videos. I can see all the comments from different videos at once. So this is just duplicate for me. As i told earlier for JMeter as of now there is VSkills certification and it is enough. It's a open source tool and so we do not have a specific certification from any org/body for it. I will make a video on it as well

[@abhinavanand4076]

Automation Step by Step - Raghav Pal Thank u sir and i am sorry sir for duplicate comments, i did't get any comment regarding Vskills so i do this, i m really sorry for this behaviour 😔😔😔😔

[@RaghavPal]

Thats okay Abhinav, just wanted to let you know as I was getting too many duplicate comments. And I will soon create a video where I will explain this. It will help others too.
