How to set up a method that takes an implicit parameter in scala using Mockito

I get the familiar "Invalid Argument Usage" trying to set a method that takes a regular parameter and an implicit parameter.

trait MyLogger {
    def debug(msg: => Any)(implicit context: LoggingContext)
}

val implicit lc = EmptyLoggingContext
val myMock = mock[MyLogger]

when(myMock.debug(any())(any())).thenAnswer(
    new Answer[Unit]() {
        override def answer(invocation: InvocationOnMock): Unit = ???
    }
)

      

        
        
        
      

    

With the above, I get "2 responders, 1 recorded"

If I change it to:

when(myMock.debug(any())).thenAnswer....

      

        
        
        
      

    

I am not getting a pairing error, but the response override is never called.

I've also tried:

when(myMock.debug(any())(any(classOf[LoggingContext]))

      

        
        
        
      

    

which again gives the expected error in 2 responders.

Any suggestions greatly appreciated.

Thank.

UPDATE: The problem here is that msg is a by-name parameter which is not mockable in mockito
