SBT test does not work for spark test

Question

I have a simple spark function to test DF windowing:

    import org.apache.spark.sql.{DataFrame, SparkSession}

    object ScratchPad {

      def main(args:         


        

Answer 1

Folowing quick and dirty hack solves the problem

System.setSecurityManager(null)

Anyway as it's related to automated tests only maybe it's not that problematic after all ;)
