      Description

      Duplicated string literals make the process of refactoring error-prone, since you must be sure to update all occurrences.
      On the other hand, constants can be referenced from many places, but only need to be updated in a single place.

      Exceptions

      To prevent generating some false-positives, literals having less than 5 characters are excluded.
