Hi Mukesh, I have been working on selenium from few days now. I am a beginner in selenium. Thanks a lot for all the videos you have uploaded on selenium. helped me a lot. If possible please help me with below : 1. How can we check actual vs expected results through selenium? 2. I create test cases and execute on my system. How can i share it with the team and then they test it on their system? Do they have to install eclipse? is there any way to just use the jar file or something and run the test case in multiple tester systems? Thanks, Ganesh

Hi Mukesh , It really helped me a lot. Thank you for all your efforts. I have a question like if I have to run multiple XML files using runner then how can I get the testNG results within one report. As we know one XML file have one suite. but in my case I want multiple XML file to run within one suite..please suggest me. Thanks

[@gauravgoyal1646]

Hi mukesh in which video tutorial you used ItestResults....

[@cashedge1]

if I add this runner class to my framework and just execute my test cases in normal way then all failed test cases will be rerun ? how testng will know I have to run this class post test execution ?

[@Mukeshotwani]

Thanks Supriya

Hi Mukesh, if there 100 of methods that are failing, then every time I have to give path for 100 of my methods in the array list?

[@amitdhanke4013]

fabulous :)

[@Mukeshotwani]

Thanks AMit

[@farheenahmad2478]

Hey Mukesh, thanks for such amazing explanation, i have one question, which is the special feature of List you are using which is not in Array List?

[@Mukeshotwani]

Hi Farheen, Arraylist has all feature of List too. Since Selenium returns List so we have to accept as list only.

[@vilaskhandare8100]

Thanks sir for such nice video. I want to know in second scenario is it nessesary to use main method ? Or can we use testNg annotation instead?

[@Mukeshotwani]

Hi Vilas, in order to use this feature you have to use TestNG only.

[@rahilkumar3558]

When this Code will execute if any testscript fail? means on what conditions it will run and for how many times it will run?

[@samshoaib6871]

Hi Mukesh, Whats the difference between this and iRetry Analyzer?

[@abhiatYT]

Can't we do via IRetryAnalyzer ? Which approach is recommended ?

[@nagulmeerashaik3336]

Hi Mukesh Frist of all deeply Thanking you so much to uploaded this type useful videos, I learned a lot from your videos. I faced some interviews a few days back still I'm searching for Automation job but when I faced in interview on java concepts most off Interviewer asking on java I would like to know where we use Method overloading and Method overriding concepts in selenium during writing scripts

[@Mukeshotwani]

Overloading we used in iFrame topics and Overridding used in Listener learn-automation.com/handle-frames-in-selenium/ learn-automation.com/what-is-testng-listener-and-how-to-implement-in-selenium/ learn-automation.com/what-is-listeners-in-selenium-webdriver/

Hi Mukesh, Thankyou so much for sharing your knowledge with us..May I know how to capture screenshot for failed tests using TestNG listners. Thanks in advance.

[@Mukeshotwani]

Hi Veda, Here is the sample code for the Listener learn-automation.com/what-is-listeners-in-selenium-webdriver/

[@devopslab-livescenarios1302]

Thanks Mukesh! I have a doubt Like 1 out of 3 TCs is failing initially, so 1 testng-failed.xml file gets created. i did correction in my the failed test case(which is correct now - i.e - i wrote Assert.assertTrue(true) - pass condition) i did refresh the package an created a Test-Runner class and run that class. now it should show me the "Total tests run: 1, Pass: 1, Skips: 0" but its showing "Total tests run: 1, Failures: 1, Skips: 0" is this the correct behavior, Yes/No - Kindly explain?

[@Mukeshotwani]

Hi Minaxi, Ideally, this should show "Total tests run: 1, Pass: 1, Skips: 0" after correction Please rerun the test all should pass

[@sandeepreddy6098]

Hi mukesh, I like the above topic but has simple question.If one test case hs been failed an d it depends on other test case then at that how can re execute the failed test case without opening browser

[@HArjoC]

I have one question, When the failed test cases are stored in failed xml folder. Can we trigger this in a script where we dont have to run manually from the tester runner page?

[@Mukeshotwani]

Yes Harjo, why not you can run testng.failed.xml from script as well.

[@srikanthy6844]

what is threadpoolsize in selenium ???

[@abhilashtc]

Use IRetryAnalyzer which is more effective and structured...

[@antoraja578]

Hi Mukesh, you have executed the failed test case initially, so again one folder gets created, so everytime if you run a failed test case then a new folder will get created every time?

[@Bell4Fun]

No , butyou have to follow the same steps as mention during the execution, and it will ask to replace the existing *.xml and html say yes if you want to over write else no and hence you utilize the existing path.I hope it helps

[@prasannakulkarni3350]

will it run the testcases after this assert code testcase??

How to build only failed test cases in jenkins? Example i have 200 test cases and 25 has failed. so how to build only failed test case?

[@nityaranjan8554]

Hi Mukesh, Just a doubt for this approach. By running this TestRunner class we can't get the class names which are failed. we just found in console output that 1 TC is failed. So how can we know which TC is failed. Can you explain this.

[@Mukeshotwani]

Hi Nitya when you open failed-testcase.xml file you will get all details about class and methods

[@slrumon]

thanks vai.I will never get bored of watching ur video. how can I do the same thing with JUnit???

[@Mukeshotwani]

Hey Khaled thanks mate :) For junit I am not sure because I have not worked on Junit much... I can give a try and will let u know soon.

[@slrumon]

thanks for reply. i found it for junit. let me know if u have anything about allure reporting.

[@Mukeshotwani]

Hi Khaled I have not used Allure reporting. You can try with extent report

[@swanandmahurkar7082]

What about skipped testcases ? what if i want to run skipped and failed testcases together ? please reply

[@Mukeshotwani]

HI Swanand skipped and failed both can be executed with same xml file.

[@Exam99839]

i handle 50 test case but the 25 case only failed other case need for run so how to write code

[@Mukeshotwani]

HI Karthi, you have to fix the failed test cases and run the tesng-failed.xml file

[@prasannakulkarni3350]

hi mukesh I wanted to know that from a list of test cases, for eg: 100 test cases are there among them i want to run first 10 an then last 20 test cases .....how can we do it , please explain...?

[@Mukeshotwani]

You can use Group feature in this case.

[@rajeevbhaskar7814]

How to do it in Nunit?

[@nekkantivenkateswararao1386]

Sir y we r using main method in testng,in testng annotations will be plays major role na sir

[@Mukeshotwani]

Yes, correct but this requirement is different. If you want to run failed test cases (using testng-failed.xml)manually then you dont need any main method. If you want to trigger the xml automatically ten you can use main method or @Test to run the xml file.

15:55 you are running the failed test but its again failed right ?

Yes Krishna because we havent fixed the script. Once you get failed test you have to fix it and then run the test again.

Hi Mukesh, please close all the unwanted tabs in Eclipse while explaining.

[@priyasai935]

Hi Mukesh, thanks for your great work! I'm a new comer to Selenium. I installed Java, Eclipse and added selenium jar files. I tried to write my first program using webdriver for IE browser (as this is only browser at my work) I downloaded IE driverserver.exe and added a code for System.setproperty etc.. but when i wrote 'Web Driver driver = new InternetExplorerDriver();' I'm not seeing 'Import InternetExplorerDriver from the down yellow box.. and also not seeing 'Import Webdriver' too. so i cannot import 'Webdriver' and 'InternetExplorerDriver'. Under the package name, i manually tried to write 'import org.openqa.Selenium WebDriver' also, but it is not recognizing and shows red cross mark.. Why is it happening? what could be the problem? can you pls help me..

How to differentiate failed ans passed testcases without reports

[@Mukeshotwani]

You can get this information in console.

[@ankitsaxenamusic]

Hi Mukesh, I have a query here. Suppose I execute my nightly builds and check the status the next day. Now the first test case has failed due to which my whole build got failed. In that case how will you trigger this logic? Since you have manually ran your runner class. Is it possible to execute the runner class as soon as the test case failed. In that case I guess IRetryAnalyser will come into picture. Kindly suggest if I'm going in the right direction. Thanks Ankit

[@Mukeshotwani]

Hi Ankit yes in running via Jenkins then IRetryAnalyser will help.

[@ankitsaxenamusic]

Thanks a lot mukesh for your quick response. Another question that came into my mind that the restriction in using IRetryAnalyser is that every class may needs to implement this. So if i am having 100 classes then everytime i would need to write the code logic in order to run the failed tests in each class. Wouldn't the code be reduntant then. What could be the solution for this? Pls correct me if i'm going in wrong direction. And thanks a lot for ur efforts in putting up such great videos.

[@Mukeshotwani]

+ANKIT SAXENA Hi Ankit no you can keep in testng.xml file so it will take care of all this..

[@ankitsaxenamusic]

Hey Deepika this error comes when no xml to run. It means all test are passed or no xml generated.

[@deepikac2250]

Thanks mukesh for your reply. I have failed xml file which is generated under test-output folder and I given correct path as well.

[@deepikac2250]

I got know the resolution. I had written 'runner.setTestNames(lst);' instead of 'runner.setTestSuites(lst); ' thats why It was not running. Now my script is running fine. Thanks a lot for providing such a helpful videos.

[@svpglb]

i am very sorry to say this but information given here is wrong. We have listeners in testng which we have to use not this way. Please update your video might give wrong information to beginners.

No issue. I didn't see the code from the video, so wrote it here in case people want to copy it :)
