An Automated Tester posted the following
“I hope you want to test infinite scroll by scrolling down to the last element. You can use mockIsIntersecting(dom.getByTestId(“datatestId”), true) from library react-intersection-observer/test-utils to test this.”
This made me think deeply:
Is it using infinite scroll if you can scroll to the last element? 🤔

Maybe in most situations, an “infinite scroll” feature isn’t truly infinite unless it is dynamically generating content. But in some cases, it’s near infinite, like in Twitter where your feed could just go on for seemingly forever because there is far more content than a human can read.
However, in that case, you could never do a test on real data that scrolls to the bottom. If you had mock data, then you could test that scrolling with limited data does reach the bottom.
I told a colleague about this and got him thinking about other claims of infinite. He said it’s like the grains of sand idea. There’s a massive amount but it’s not really infinite. Or the size of the universe; constantly expanding, but at any given time; is finite.
Mike: A line on a graph that extends out to infinity, it doesn’t though; it extends out as far as you graph.
Me: Buzz Lightyear can go beyond infinity (“To infinity, and beyond!”).
