Thank you, I will.

[@prashantht.v8289]

Superb Video Mukesh, You make it look so easy..

[@Mukeshotwani]

Hi Prashanth thank you.

[@krishanuchakraborty3500]

Hi Mukesh, since Zalenium is sort of deprecated now, can you please look into Selenoid and suggest whether it can be an alternative? If possible, a detailed video on Selenoid would be great!!!

[@umangsharma7447]

thanks for sharing mukesh.. love learning from your videos !!

[@Mukeshotwani]

Thanks Umang and I really appreciate your dedication. When everyone was enjoying new year and you were improving your skills. Keep learning.

Hi Mukesh,
Thanks for providing docker videos.
I have one question.
How to pull IE and Edge images in docker for automating tests in IE and Edge using selenium webdriver?
Could please you make video on this

[@prakashp3022]

There are no official images for ie and edge in docker. .

[@martinmcnulty8155]

Nice videos Mukesh thanks

[@Mukeshotwani]

Thank you Martin 😊

[@chaiti19]

Awesome video as always! Just a small doubt, the 2 default containers will be up always? Like in the video, it shows that the 3rd one(created on runtime) got destroyed. But the othe 2 are still shown on the console. Thanks a lot bdw:)

[@himanshigupta7473]

Hi Mukesh, With Zelenium is it possible to instantiate hub and nodes in different machines connected on same network?

[@Mukeshotwani]

Hi Himanshi, in that case you need to use Docker. Zalenium create automatic contains at runtime.

Hi Mukesh,
I am working on selenium c#, VSTS.
Can we use docker on VSTS?

[@saiprashanth6618]

Thanks Mukesh for the video.. What's the difference between Selenoid and Zalenium

[@prasadp4648]

Hi Mukesh,
Is it possible to launch multiple chrome instances on one Docker Container for parallel execution?
Thanks in advance!

[@Mukeshotwani]

Yes Prasad Zalenium support multiple instances, it will create run time container each time.

Thanks Rama 🙏

[@vinayraj2505]

Hi Mukesh, nice video by you,I have a small doubt we can just lock our system and run the scripts?

[@Mukeshotwani]

Yes Vinay selenium script can be executed in VM or in local system when it is locked. You can also run selenium script in headless mode. learn-automation.com/how-to-run-selenium-test-in-headless-mode-in-chrome/

[@vinayraj2505]

Thank you 😊

[@laxmanbinawade4278]

Hi Mukesh,
Thanks for such wonderful video, can we run test scenario on different browser version? I want to run test scenarios on old chrome and FF browser, is it possible?
please help me

[@Mukeshotwani]

Hey Laxman by default these images will have latest browsers only.

[@sampathkumar-nd2th]

Hi Mukesh,
If I execute the testcases with chrome browser, it is crashed.
Error:
unknown error: Chrome failed to start: crashed.
When I encountered the same error for selenium grid with docker, I just removed below lines
volumes:
- /dev/shm:/dev/shm
But I am unware how to resolve it in Zalenium.
Thank you in advance

[@somanianands]

Is any plan to create video with Jenkins + Zelenium?

[@trails_2]

I want to run 30 parallel tests on docker, this test consume lot of CPU. Can I achieve this with zalenium, sir

[@abhishekthomas7799]

how to configure the above script if I want to run tests on different machine rather than localhost?
Any tutorial links?

[@Mukeshotwani]

Hi Abhishek, Zalenium is only installed on local system but it is running our test on containers. You can install Zalenium on any other system/server and then you can access via ip:port

[@abhishekthomas7799]

@@Mukeshotwani ok will try. Thnx

Hi Mukesh
When I execute the command, it is not creating any nodes.

[@sampathkumar-nd2th]

I had existing selenium/hub images available, they caused the issue

[@sudhakarks4726]

Hello mukesh, thanks for video, I tried the same steps it works fine on docker but when I launch the browser localhost:4444/grid/console it says this site can't be reached but on docker cli it's running as shown in the video.
I tried with IP address also it's giving me the same error

[@Mukeshotwani]

Hi Sudharkar, execute the test and then share the logs.

[@sudhakarks4726]

@@Mukeshotwani thanks for the swift response, with out having zalanium running on my browser will my Java scripts doesn't fall in to trouble? If you are referring logs which logs you want me to share you?

[@Mohammed-yi1ku]

have you tried "localhost:4444/wd/hub"

[@sudhakarks4726]

@@Mohammed-yi1ku yes but don't work

[@alluramachandra6337]

Same issue for me also

[@shabanasarithala4672]

Hi Mukesh can you do a video on monting folders or files in zalenium server

[@Mukeshotwani]

sure Shabana can u tell me what is your requirement as of now ?

[@Mohammed-yi1ku]

Hi Mukesh,
As per "github.com/zalando/zalenium",
This is a Selenium Grid extension to scale your local grid dynamically with docker containers. It uses docker-selenium to run your tests in Firefox and Chrome locally, if you need a different browser, your tests can get redirected to a cloud testing provider (Sauce Labs, BrowserStack, TestingBot, CrossBrowserTesting, LambdaTest).
Does it mean that we can link Zelenium and SauceLab ? any referral video ?

[@Mukeshotwani]

Hi Mir Ali, yes you can use Zalenium with SacueLab too. I will record video on this too soon.

[@נתנאלכהן-ג6צ]

It's Zalenium, not Zelenium.

[@Mukeshotwani]

Thanks Buddy let me make changes.. it's small typo mistake.

[@נתנאלכהן-ג6צ]

@@Mukeshotwani No problem dude. Thanks for the video. Btw, I tried to use Zalenium in December 2018 at my work, but it had a memory leak so the tests failed. There are few bugs about this issue in GitHub. I don't know how it is works now because I gave up when I saw that they didn't fix it even after few months.
