NSStringEmojize has unit tests that actually test. This doesn't.

[DavidPhillipOster]

Please add some real unit tests.

Please add a unit test that has a single string with multiple colon synonyms in it. Keep the distance between the colon items short, like @" :\mushroom: :\mushroom: :\mushroom:" (backslashes added to keep this site's colon parser from firing.)
