As far as I know, there is no unit testing of the window function in Scala /
Python. At least, we should add unit testing in Python.

[~yuu.ishik...@gmail.com] Could you clarify which of these functions need
support for better `collect` in SparkR. We only need the collect functionality
if we are fetching data back to the driver ?
