Unit Testing Scoobi

[Deepak Jain]

I have a scala+scoobi project that does bunch of map,groupBy,combine, reduce & other scoobi operations. I would like to write unit tests around this. How do i go about it ?

1) Should i go the route of EasyMock (or Mockito) to mock DList (DList is a trait) ? 

2) Should i create a single (sample size) record(s) (actual) and run the scoobi app against it and call it as unit test (when infact its integration test)

3) I found this article  http://blog.xebia.com/2012/03/08/apply-tdd-to-hadoop-jobs-with-scoobi/  

How do i go about it ?

Do we have few examples ?
