If you've ever used Puppeteer, you'd know it enables you to control a Chrome instance (or any other Chrome DevTools Protocol based browser) and exe...

Awesome work! I'm already in love with Playwright. What I really appreciate as a developer is the seamless integration with Firefox and WebKit and not just Chromium, with no extra step to integrate or configure anything. WebDriver can be tedious on these points.
I have a pet project of mine called Instakittens that serves as a playground for testing frameworks (think TodoMVC, but for tests). I already have several test suites that use Puppeteer for browser automation, with Jest, Mocha and Cucumber as test runners. When I saw the announcement for Playwright on Twitter I had the urge to give it a try. Incredibly enough, it took me only a few hours to port the Puppeteer-based suites to Playwright with almost zero compatibility issue: apart from the initialization, I only had to replace
{visible: true}/{hidden: true}to{visibility: 'visible'|'hidden'}in selectors.Awesome work, I’ll check out your repo for sure, will save me a few hours at least 🙂
Does playwrite download its own version of the browser like Puppeteer, or can it use an existing install?
You can use it with an existing install, and avoid the binaries from getting downloaded. Check out the
playwright-coreNPM package, which does not install the binaries. We want to ensure your tests run fast and if your setup does not need the browser to be downloaded, you shouldn't have to wait.Awesome! Thank you 🙏
It downloads the binaries from official channels, not sure you can use an existing or not, will look it up
Thanks. That's my biggest issue with E2E testing FWs.
I'd like to be able to
npx playwrightand have the tests run instantly. Rather than wait 5 min for a download.Might happen, it’s open source, check the issues and see if something exists. Up vote or create one 🙂. Even better create a PR if that’s your thing
Can you use Playwright to create an Electron-like system, but with Firefox instead of Chromium?
It’s a bit early to be sure, but I see the potential
Great tool!
How does Playwright communicate with the browsers?
Chromium is accessed via CDP as far as I know. But for the rest I found nothing.
Have a look at connect method on this file for example
github.com/microsoft/playwright/bl...
Yes I am extremely excited to start using this library
How does it address flakiness in E2E tests though? If it's true than it could be as good as Cypress (little flakiness) and Selenium (multiple browser support) combined.
I’ll be exploring this further as I mentioned, if you have a codebase with e2e tests, do try it out and give feedback as well
We built a cloud platform where anyone can create, manage and execute automated tests for Web and Mobile Applications.
We would love to get some unbiased feedback from your side.
