Subject: Unit testing Spark/Scala code with Mockito

On a second note with regard Spark and read writes as I understand unit
tests are not meant to test database connections. This should be done in
integration tests to check that all the parts work together. Unit tests are
just meant to test the functional logic, and not spark's ability to read
from a database.

I would have thought that if the specific connectivity through third part
tool (in my case reading XML file using Databricks jar) is required, then
this should be done through Read Evaluate Print Loop – REPL environment of
Spark Shell by writing some codec to quickly establish where the API
successfully reads from the XML file.

Does this assertion sound correct?
