How would one run unit tests with <code>nose</code> for Apache Spark applications written in Python? With <code>nose</code> one would usually just call the command <pre class="prettyprint"><code>nosetests </code></pre> to run the tests in the <code>tests</code> directory of a Python package. Pyspark scripts need to be run with the <code>spark-submit</code> command instead of the usual Python-executable to enable the import of the <code>pyspark</code>-module. How would I combine <code>nosetests</code> with <code>pyspark</code> to run tests for my Spark application?

If it helps we use nosetest to test sparkling pandas. We do a bit of magic in our utils file to add pyspark to the path based on the SPARK_HOME shell environment variable.
