Playwright
Playwright is Microsoft's open-source framework for browser testing: an API for Chromium, Firefox, and WebKit, stable and fast.
Playwright is an open-source framework from Microsoft for browser automation and end-to-end testing, released in 2020. With a single API, you can control Chromium, Firefox, and WebKit, effectively covering Chrome, Edge, Firefox, and Safari. It's developed by a team that previously worked on Google's Puppeteer, with new releases appearing monthly.
Its primary application is automated testing of web apps: click paths, logins, and checkout flows are automatically verified with every release. Additionally, Playwright is suitable for scraping and browser agents. Its strength lies in its stability, as auto-waiting and the Trace Viewer significantly reduce the dreaded test flakiness.
Compared to Selenium, Playwright is more modern and faster, but also newer. The Selenium ecosystem is larger, and only Selenium covers some legacy browsers. One thing is clear: you won't get anywhere with either without programming skills.
It's the top choice for development teams starting with automated browser tests today. Business departments without developers are left out — for simple, no-code web automation, Zapier or Make are more suitable.
Functions
