Understanding all-new Dynamic Selenium Grid 4 along with video support!

[@sksingh329]

Thanks Karthik for creating this video.. Nicely explained!

[@ashwinraj8526]

Thanks for the wonderful video , I have the video image in toml file though the videos are not recording and I dont see the image running.

[@mizanur968]

Amazing info, Thanks for the video

[@Nandhis]

Thanks karthik 👍

[@Utub-qc2cz]

Would you please share your experience on how is the performance of Selenium Grid when executing many parallel tests ?

[@MrSno80]

I'm getting an issue where after execution is completed nodes keep busy so running again makes the test failing. Do you know why?

[@b8addict]

Is it possible to only record failed test cases and any way to set the fileName to the test case itself?

[@queenstownswords]

nice! I think this may put Selenium 4 above PlayWright at this point. Do you have any insights on 'best practices' to manage the videos with Selenium 4 Grid in a Jenkins or Azure pipeline?

[@ExecuteAutomation]

Selenium is always best than Playwright, but these grid execution features are awesome and will go well with Pipelines pretty well !

[@addessamerda]

@@ExecuteAutomation - On top of that, it would be very nice if you could share a short tutorial of how to integrate playwright with dynamic grid via docker-compose. I've seen many people (including myself haha) struggling to make them work together regardless the OS (Linux/Windows), it's tricky to make they work properly. Anyway, thanks for all the great content you have shared with us, man. You have always been my #1 reference for learning new testing stuff.

[@TastyGrub]

Hi thanks for the video! Can you explain how the auto scalling works? I do not see new nodes getting created

[@satyaguddu508]

how to set maximum concurrency of individual browser in Selenium Grid 4?

[@toothlessanaconda7707]

It's a nice video. I've tried and it worked but the video is not saving for firefox and Microsoft Edge browser. It's not creating the folder with the session id. Those scripts run on chrome, I'm getting the video file for those scripts only. Can you please provide any solution to this? How I can manage to get the video for firefox, edge browser? I've added the se:videoRecord true for all the browser capabilities but it's not working.

[@jeffreyschmidt2159]

Do you have any idea how this could be done on AWS? both the dynamic grid and the video recording (hopefully saving to an s3 drive).

[@MrSno80]

That spring basic code looks good. Is there any course regarding that code?

[@ExecuteAutomation]

Here mate www.udemy.com/course/spring-boot-testing/ Use coupon code EA-MAR-22 for discount if you are planning to take it up

[@namilkim4523]

Can you put a way to apply it on multiple VMs rather than local formats on KZbin?

[@joaopaulooliveirasantos7733]

Is there an alternative software that people that use VM’s can use for this??? Docker doesnt work inside virtual machines unfortunately

[@ExecuteAutomation]

Enable nested virtualisation to make this work, VMs supports them

[@joaopaulooliveirasantos7733]

Thank you! Also, do you have any updated material on Specflow using Page objects?

[@Kuznecoov]

Thanks for video! Very helpful. I am thinking how to volume own chrome profiles via config.toml

[@mizanur968]

I see that there is 4 default chrome browsers, can we increase it to n numbers?

[@ExecuteAutomation]

The number of sessions you run, the number of chrome browsers will launch
