We are at the very initial state of building e2e regression tests. I found that Playwright fits us because it pierces shawdom DOM, supports page objects by default and supports Python. Most of our QEs use Python for test automation. But I don't see many people talking about this technology in the channel. So did anyone try Playwright?
I'm a big fan of Robot Framework. Take a listen to the Salesforce Developer's Podcast Episode 59 where Josh Birk interview Pekka Klarck the lead developer here https://www.youtube.com/watch?v=-PxPps1BQuw
I do have some Bias as I work for Copado and we have Copado Robotic Testing which an an E2E functional testing tool that is designed for Salesforce and built on the Robot Framework. Copado acquired Pekka's previous employer Quentinel which formed the core of the Copado Robotic Testing solution. We extend Robot Framework to have a more complete and accessible solution. And we are members of the Robot Foundation that Pekka works for today! So if you want to buy a solution check out Copado. https://www.copado.com/platform/test/
If you want to build consider the Robot Framework. You can get some good documentation on how to do it from Julian Joseph's video here: https://www.youtube.com/watch?v=B03PY9RUUqw
