It has been advised by @mengxr to keep doctests and testing for correctness
separately. (https://github.com/apache/spark/pull/6499#discussion_r32784734)
It might be better to just write sameModel.transform("a") and write a small
test to test model and sameModel give same results using `getVectors` maybe?
