> 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.
