Solve the following python programming problem given the following code:
@ with_config ({ 
    'spark' : { 
        'py-packages' : 'dummy_test_module', 
}, 
}) 
@ patch.dict ('sys.modules', { 
    'pyspark' : MagicMock (), 
}) 
@ patch ('pyspark.SparkContext') 
def test_pyspark_runner(self, spark_context) : 
    sc = spark_context.return_value.__enter__.return_value 
    def mock_spark_submit(task) : 
        from luigi.contrib.pyspark_runner import PySparkRunner 
        PySparkRunner (* task.app_command () [1 :]).run () 
        self.assertTrue (os.path.exists (sc.addPyFile.call_args [0] [0])) 
with patch.object (SparkSubmitTask, 'run', self) : 
        job = TestPySparkTask () 
        job.run () 
sc.textFile.assert_called_with ('input') 
    sc.textFile.return_value.saveAsTextFile.assert_called_with ('output')
