We already have abstractions in the API tests (`self.platformContext.{shlib_prefix,shlib_extension}`) which exist precisely for this reason. There's no function to automatically construct the library name (you have to do the concatenation yourself), but I certainly wouldn't be opposed to adding one.

If they're going to be testing the exact same thing, then I don't see a reason for keeping these around.
