playwright vs puppeteer

Tagged with node, webdev. Puppeteer is getting a lot of buzz as a way for JS developers to create E2E/UI tests. The drama started immediately.

Puppeteer can drive either Chrome or Chromium (the open-source browser that Chrome is based on), and by default, installing Puppeteer also downloads a compatible version of Chromium. , Active Reliability for Modern DevOps Teams, Running against a real-world web application, Puppeteer vs Selenium vs Playwright, a speed comparison. See All by taminif . … We were also quite interested in testing out the new DevTools mode. Instead of guessing why errors happen, or asking users for screenshots and log dumps, LogRocket lets you replay the session to quickly understand what went wrong.

The launch tweet from Andrey Lushnikov (who’s Twitter bio is “former TL @ Chrome Puppeteer, former eng @ Chrome DevTools”), is responded to by Sam Sneddon who questions the cross-browser compatibility. We were therefore very keen to have the benchmarks run against a production application. You can check the status of the test suite at the Is Playwright Ready? For each benchmark, we gathered data from 1000 successful sequential executions of the same script. returns: This object can be used to launch or connect to WebKit, returning instances of WebKitBrowser. Less surprising is perhaps that running Puppeteer without any added higher-level framework helps us shave off a significant amount of execution time on this very short script. First off, let us rank the tools from fastest to slowest for both testing scenarios: This first benchmark brought up some interesting findings: Speed is important, but it can't tell the whole story. Currently it has more activity, growing traction and introduces new features faster than Puppeteer. Playwright or Puppeteer? In this first scenario, performing a quick login procedure, we expected an execution time of just a few seconds, great for highlighting potential differences in startup speed between the actual tools. Eventually, programmers started using headless browsers in some cases. Looking at the progress on both sides, we wonder if the future will bring DevTools to the forefront, or if WebDriver will keep enjoying its central role in browser automation. This approach was later abandoned as we encountered issues on the Selenium side, with the session becoming unresponsive after a certain number of cookies had been loaded. Playwright vs Puppeteer.

I wondered why Playwright is better – a new tool that neatly rests on GitHub in a Microsoft organization. The Chrome DevTools team develops it, giving it a major advantage over similar projects because it has institutional support from the same company that makes the most widely used browser in the world. Google followed up headless Chrome with the public release of Puppeteer a few months later. As we saw up with the differing devices, we call the launch function directly from a browser type with const browser = await chromium.launch({ headless: false }); . Proportionally, the difference between the newer tools and both flavours of WebDriverIO is also lower. ├── @wdio/sync@6.10.0 Playwright is a Node.js library for browser automation. But is it better than Selenium? Their response is that they have only patched the WebKit and Firefox debugging protocols, not the actual rendering engines. By using the Playwright API, you can write JavaScript code to create new browser pages, navigate to URLs and then interact with elements on a page. # Choosing selectors.

Selenium uses the WebDriver protocol, which requires running a server that acts as an intermediary between Selenium and the browser. Among the results of our benchmark were also some unexpected findings, like Puppeteer being significantly faster on shorter scripts and WebDriverIO showing larger than expected variability in the longer scenarios. It can drive Chromium, WebKit (the browser engine for Safari), and Firefox. Memory: 16 GB, bench-wdio@1.0.0 /Users/ragog/repositories/benchmarks/scripts/wdio-selenium Run your own benchmark!
