> Sometimes using {{withOutput}} and {{runTest}} is not possible if the
> {{.equals}} method is not the correct way to compare equality. This is
> especially true for Mapper and Reducers that return doubles or structure with
> doubles in them, since there is no way to specify a desired error tolerance
> for the result.
> Being able to specify a {{Comparator}} for the key and value types enabled
> the usage of {{runTest}} for these cases.
