Comment (by SergeyBiryukov):

 This reminds me of comment:1:ticket:47701 and [45646] / #47701:
 * [source:tags/5.8/tests/phpunit/tests/functions/wpGetMimeTypes.php].

 I think something similar would be enough here:
 * Make sure it returns an array.
 * Make sure it's not empty.
 * Make sure the filter works as expected.
 * Make sure it reverts to the original array after removing the filter.

 While the latter two steps might technically be out of scope here, I agree
 that if the function result is supposed to run through a filter, testing
 for that specifically seems like a good idea.
