Ted Dunning commented on MAHOUT-1059:
-------------------------------------
Good comments. Your comment about which class is being tested is pretty much
on target.
I would like to build an AbstractVectorTest for testing vectors in general.
That should help a bit.
Is the mocking necessary? Adding the a mocking package as a test dependency is
fine, but perhaps not yet needed.

> The upcoming clustering needs several capabilities to support different
> operations. These include some matrix extensions for adding behaviors to
> different kinds of matrices. Also there is a file based matrix that uses
> mmap to access a file as if it were a matrix in shared memory. Since this is
> off-heap and shared between processes, it can seriously help some programs.
