Check out system requirements for details. For high-dpi devices, this will keep screenshots small. infinite animations are canceled to initial state, and then played over after the screenshot. Tracing. Using "device" option will produce a single pixel per each device pixel, so screenhots of high-dpi devices will be twice as large or even larger.#, threshold? finite animations are fast-forwarded to completion, so they'll fire.

Note that only native control elements such as HTML button, input, select, textarea, option, optgroup can be disabled by setting "disabled" attribute. // Bring some structure to your snapshot files by passing file path segments. Now to execute the test in one browser and in headed mode, we will use the command: We should see that the test succeeded and an HTML report is generated. By default, the timeout for assertions is set to 5 seconds. // Contains the right items in the right order, // Locator points to the outer list element, not to the list items, // Has the right items in the right order. await expect(page.locator(div#flash)).toContainText(You logged out of the secure area!)
