Playwright module provides a method to launch a browser instance. The following is a typical example of using Playwright to drive automation:

The playwright.config centralizes configuration: target browsers, timeouts, retries, projects, reporters and more. In existing projects dependencies are added to your current package.json.

Playwright is aligned with the modern browsers architecture and runs tests out-of-process. This makes Playwright free of the typical in-process test runner limitations.

By default, Playwright runs the browsers in headless mode. To see the browser UI, set headless option to False. You can also use slow_mo to slow down execution. Learn more in the …

The Playwright library can be used as a general purpose browser automation tool, providing a powerful set of APIs to automate web applications, for both sync and async Python.

Playwright Library provides unified APIs for launching and interacting with browsers, while Playwright Test provides all this plus a fully managed end-to-end Test Runner and experience.

Playwright can run your tests in multiple browsers and configurations by setting up projects in the config. You can also add different options for each project.

Playwright checks for the overlay every time before executing or retrying an action that requires an actionability check, or before performing an auto-waiting assertion check. When overlay is …
