The Puppeteer library provides a high-level API to control Chromium-based browsers, including Microsoft Edge, using the DevTools Protocol. See Use Playwright to automate and test in Microsoft Edge. Headless browsers don't display a UI so generally you use the command line - however, you can also configure Playwright to run the full Microsoft Edge UI. Playwright launches browsers as headless, by default. Playwright enables cross-browser web automation that is evergreen, capable, reliable, and fast. The Playwright library provides cross-browser automation through a single API.

You can also provide feedback to browser engineers and the web standards community about the design of the API, your use cases, or your experience using the APIs. To see a list of the available origin trials and register your origin to give them a try, see the Microsft Edge Origin Trials Developer Console. To access the experimental APIs on each user machine, you don't need to go to edge://flags and turn on feature flags. When using Origin Trials, users of Microsoft Edge that visit your site may run code that uses experimental APIs. You can use Origin Trials to try out experimental APIs on live sites for a limited period of time.

For information about how Microsoft Edge uses the Chromium open-source project, see Microsoft Edge and Chromium Open Source: Our Intent. By building Microsoft Edge on the Chromium open-source project, the Microsoft Edge DevTools Protocol matches the APIs of the Chrome DevTools Protocol. Use the DevTools Protocol to instrument, inspect, debug, and profile browsers, including Microsoft Edge. Provides advantages over JavaScript unit tests.Ĭhecks your code for best practices and common errors, to test and improve accessibility, performance, cross-browser and PWA compatibility, and security of your site.
