Subject MR-Unit vs JUnit for unit testing
Date Tue, 12 Apr 2016 07:51:10 GMT
Hello everyone,

I have heard about MR-unit and I was wondering if someone could explain 
to me what is the gain of using MR-Unit for unit testing MR jobs 
compairing to usage of JUnit and Mockito?

Concretely, what are the things that I can do that I cannot do them 
using JUnit, or it is much more difficult?

My idea is to move all the logic from mappers/reducers to helper classes 
and just verify that appropriate methods are called on the mocks.

Why use MR-Unit?

Best regards,
