Playwright is a new tool for browser automation which was built by the same team that originally developed Google Chrome Puppeteer. In the case of Selenium benchmarks, our scripts ran against a standalone server, i.e. Headless browsers can work well for testing simpler websites, but to test everything that websites can do, they need to emulate full browsers as closely as possible by supporting various web standards. Puppeteer: Yes Playwright: Yes Parallelism Grids and Infrastructure. With a recent update to Azure Functions, it is now possible to run headless Chromium in the Linux Consumption plan.

It is worth noting that the latter two are now producing more variable results compared to the previous scenario, while Puppeteer and Playwright are now displaying smaller variations. Selenium tests are commonly flaky, failing intermittently for non-obvious reasons that are difficult to reproduce. We still recommend you take the time to go through it, so that you can better understand exactly what the results mean. ├── @wdio/cli@6.9.1 On longer E2E scenarios, the difference seems to vanish.
