Databricks Fixtures for PyTest

This creates fixtures for running tests as jobs in Databricks. This does NOT use the yield keyword since the fixtures load the existing context natively

import pytest

@pytest.fixture
def spark():
  import pyspark
  from pyspark import SparkContext
  from pyspark.sql import SparkSession

  sc = SparkContext.getOrCreate()
  spark = SparkSession()

  return spark

def some_test(spark):
  from pyspark.dbutils import DBUtils

  dbutils = DBUtils(spark)
  # test
