Hi,
How about org.apache.giraph.utils.TestGraph?
I would not try using mrunit for testing Giraph.
cheers

Hi Martin,
it depends on the details of your implementation. In principle, you do
not write Mapper and Reducer
classes, which are tested by MR-Unit. You usually have to implement
the application / algorithm specific
logic, in e.g. the Vertex class. MR-Unit might not help that much here.
This leads to the question, if there is a comparable approach / or
tool like MR Unit for Giraph?
Best wishes
Mirko

How much of the Giraph 1.1.0 version is still based on MapReduce?
Would something like mrunit (http://mrunit.apache.org/) work with it?

I'm using the Yarn version (1.1.0 trunk) and I was not able to
get it to work that way. But I'm no expert on that, if anyone
knows a way to get it done It would be great.

I find running Giraph apps via hadoop's local execution mode
quite useful for debugging.
Thanks,
