> 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.
