Breakpoints not hit with Scalatest + intelliJ

[Michel Lemay]

Hi,

I'm adding unit tests to some utility functions that are using SparkContext
but I'm unable to debug code and hit breakpoints when running under
IntelliJ.

My test creates a SparkContext from a SparkConf().setMaster("local[*]")...

However, when I place a breakpoint in the functions inside a spark
function, it's never hit.

for instance:

rdd.mapPartitions(p => {
  myFct(...)
})

Any help would be appreciated.
