I am trying to write the unit test case for my private method in scala using MockitoSugar but it is throwing Can't find a private method exception. Here is my code.
      object ActivityRepo{
        private def addActivity(activity:Activity):Future[Activity]={
              //doing DB calls
          }
      }
Unit test:
      "Activity Repo Test" must {
        "add Activity" in {
          // doing mock for the DB calls
          val addActivity = PrivateMethod[Future[Activity]]('addActivity)
          val result = ActivityRepo invokePrivate addActivity (activity)
          // doing assertions      
         }
      }
Where is the mistake?
