>From github comment by Dmitriy:



also on the topic of test suite coverage: we need to pass our standard tests. The base clases for them are:

https://github.com/apache/mahout/blob/master/math-scala/src/test/scala/org/apache/mahout/math/decompositions/DistributedDecompositionsSuiteBase.scala

https://github.com/apache/mahout/blob/master/math-scala/src/test/scala/org/apache/mahout/math/drm/DrmLikeOpsSuiteBase.scala

https://github.com/apache/mahout/blob/master/math-scala/src/test/scala/org/apache/mahout/math/drm/DrmLikeSuiteBase.scala

https://github.com/apache/mahout/blob/master/math-scala/src/test/scala/org/apache/mahout/math/drm/RLikeDrmOpsSuiteBase.scala

The technique here is to take these test cases as a base class for a distributed test case (you may want to see how it was done for Spark and H2O). This is our basic assertion that our main algorithms are passing on a toy problem for a given backend.
