Why add the word "Shortcut" on the front of these two types?  Seems like it just
adds verbosity for no (or negative) clarity, and there aren't symbol conflicts
I'm aware of that would necessitate this.

Similarly, I think the names below could be briefer and clearer by omitting most
of the instances of "Shortcut" (e.g. struct TestData, void
PopulateShortcutsBackendWithTestData(), etc.)

Nit: Prefer type aliases to typedefs

There are currently no symbol conflicts, but I am uncomfortable putting classes
named "TestData" and "ExpectedURLs" into the global namespace.  I think that's
asking for conflicts in the future.  I'd like to keep the "Shortcut" in
TestShortcutData, but I will shorten the "Populate" method name as you
suggested.  I've also dropped the "Shortcut" prefix from the typedefs.
Done.
