Mockito matchers, scala value class and NullPointerException

Question

I\'m using mockito with scalatest. I have following problem when using matcher with value class.

import org.scalat         


        

Answer 1

My class also extended AnyVal

case class ApplicationKey(value: String) extends AnyVal {
  override def toString: String = value
}

and this worked for me:

   when(waterfallLogicEventWriter.writeAuctionEvents(            
     Eq(waterfallRequest.auctionId), Eq(waterfallRequest.ip),
     ApplicationKey(any[String]),                                
     any()).thenReturn(waterfallEvents)
