TypeError: scrollIntoView is not a function

If we want to unit test 'scrollIntoView' function in a react application using react testing library then we can mock the function using 'jest'.

window.HTMLElement.prototype.scrollIntoView = jest.fn()

scrollIntoView is not implemented in jsdom. Here's the issue: link.

You might get it working by manually adding it:

window.HTMLElement.prototype.scrollIntoView = function() {};
