Playwright Test Structure in Details -Session-02

How to Maximize a Browser window using Playwright Java

  Playwright itself does not have a direct maximize () method like some other browser automation tools, but you can achieve the effect by setting the viewport to the screen size of your display. Below are ways to handle Maximize a browser in Playwright Java  Ø   Setting the viewport to the screen size  o    setViewportSize(1920, 1080): This sets the browser window to a full HD resolution, effectively maximizing it. o    setHeadless(false): Ensures the browser runs in a visible mode so you can see the window being maximized.  Code Snapshot  Playwright playwright = Playwright. create ()   ;   Browser browser = playwright.chromium().launch(new BrowserType.LaunchOptions().setHeadless(false));     // Create a new browser context   BrowserContext context = browser.newContext(new Browser.NewContextOptions()          .setViewportSize(1920, 1080));     ...
