Why isn't Cypress scrollIntoView working reliably in my tests?

I’m using Cypress on Windows 10 with Chrome 92. I want to scroll to a button before clicking it, but sometimes the element is not visible or clickable. scrollIntoView doesn’t always bring the element into the center of the viewport, and tests intermittently fail with an “element not visible” error. I need a reliable way to scroll and interact with elements.

By default, scrollIntoView aligns the element to the top of its container, which may not center it in the viewport. Page layout, CSS, or dynamic scripts can interfere with scrolling. Adjusting the alignment can improve reliability:

cy.get(‘#your-button-id’).scrollIntoView({ block: ‘center’ }).click();

This scrolls the element to the center of the viewport. Ensure no scripts or CSS dynamically reposition the element after scrolling. Adding assertions for visibility can also prevent flaky tests.

Animations, lazy-loading, or scripts that animate elements on scroll can cause timing issues. The element might not be fully positioned or visible when Cypress tries to click. To stabilize tests, wait for the element to be visible after scrolling:

cy.get('#your-button-id').scrollIntoView().then($el => {
  cy.wrap($el).should('be.visible').click();
});

Consider disabling animations in test environments or using cy.wait for any delayed effects. Adjusting the viewport or stubbing animation scripts can also improve reliability.
