As a developer about to go down the e2e testing pipeline for our new products and chosen puppeteer, I would also be very interested in this.
See also https://www.testfront.io/ for an actual description of how it works, but don't bother signing up. I'm really bad at marketing/getting the word out, and google took forever to approve the extension so I lost interest/ran out of money. Maybe if others show interest, I'll be motivated to resume the plans I had for it.
Here's a 4 minute video of it in action, covering every user join/login/update possibility: https://www.youtube.com/watch?v=ifkaptIYeL8
We switched it out for puppeteer as it was more suited as a library for our-case. Cypress is a great batteries-included E2E solution though.
