Maximize Window | Playwright Tutorial - Part 72

• 02:27 Setting viewport as null in playwright.config.ts
• 03:04 Enabling args as --start-maximized for Chromium-based browsers
• 04:16 Setting viewport for a specific test

In this video tutorial, the instructor explains how to maximize the browser when running test scripts using Playwright. By default, the browser launched with Playwright is not maximized, unlike Selenium.

The video provides two methods to maximize the browser.

The first method involves modifying the playwright.config.ts file. By setting the viewport to null and enabling the args option with --start-maximized for Chromium-based browsers, the browser will launch in maximized mode. However, the --start-maximized option only works for Chromium and not for Firefox or Webkit browsers.

The second method allows for specifying the viewport size for a specific test. By using test.use and providing the desired height and width, the browser will be launched in a specified viewport. The instructor suggests using the window.outerWidth and window.outerHeight properties in the browser console to determine the appropriate width and height values.

The instructor demonstrates the second method by providing a sample height and width and executing the test script. However, it is mentioned that this method only sets the window size and not the maximized mode as seen in the first method.

The video concludes by mentioning that the first method works for all browsers but the second method only works for Chromium-based browsers. The instructor also mentions that they were unable to find a maximized configuration for Firefox.

Overall, the video provides a quick tutorial on maximizing the browser when using Playwright and offers two different methods to achieve this goal.
