It'd be useful to know how Google deals with URLs that end with a trailing slash vs a non-trailing slash in cases where the content is completely different.
In the vast majority of cases, when a URL renders with both a trailing slash and without (without one version redirecting to another), the content is duplicated. Despite that, it actually is possible to render different content - strictly speaking, they are two different URLs and should be able to serve different content should they want to. Try this URL without the trailing slash, for example.
It's not uncommon to see sites serve content at both URLs - albeit usually duplicate - and this test would be a nice way of showing that search engines would be doubling their crawl budget and technically treating both URLs as seperate pages.
My guess is that both URLs will end up indexed.
