Yes, tests and update for the
[docs](http://zeppelin.incubator.apache.org/docs/development/howtocontributewebsite.html)
will be great to see as part of this PR indeed!
BTW Spark interpreter does not require Spark installed on the same machine
with Zeppelin.
Depending on the way you [run
Zeppelin](https://github.com/apache/incubator-zeppelin#setting-spark_home-and-hadoop_home),
it can use embedded Spark (actually, by default) so it will work in local mode
without any external dependencies.
