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.
