The Cypress scrollIntoView() command scrolls the webpage until a specific DOM element enters the viewport's visible area, waiting for 4 seconds (by default) for elements to become visible on the page. This wait duration is customizable, and it can be used to reduce test flakiness for pages with hidden elements, dynamic content, lazy-loaded images, and infinite content. The command can also be chained with assertions or actions like click(), type(), etc., ensuring that the tests accurately mimic real user interactions. Additionally, the Cypress scrollIntoView() command provides various options such as easing animation, offset pixels to be scrolled after the element is scrolled into view, timeout for resolving before it results in a timeout, and more.
