mahout test

[Cui tony <to...@gmail.com>]

Can anybody give a brief introduction on how to write mahout test? I need to
make a test on an algorithm and I have not found the way.

Thanks!

What kind of algorithm do you want to test? If it is pure Java you can 
write a unit test; look in one of the testing folders for many examples. 
If you want to test a MapReduce algorithm, you can write it in a unit 
test too, it is just a little more complicated. Look in the clustering 
tests for several examples. In these tests we use a dummy output 
collector (in-memory version of the Hadoop collector) and test it similarly.
