Does Java – mockito have the same idiom as jmock’s country?

The book "object oriented software" provides several examples in jmock, in which the state is explicit and will not be exposed through the API I really like the idea Is there any way to do this in mockito?

This is an example of this book

public class SniperLauncherTest {
   private final States auctionState = context.states("auction state")
                                              .startsAs("not joined");

   @Test public void addsNewSniperToCollectorAndThenJoinsAuction() {
     final String itemId = "item 123";
     context.checking(new Expectations() {{
       allowing(auctionHouse).auctionFor(itemId); will(returnValue(auction));

       oneOf(sniperCollector).addSniper(with(sniperForItem(item)));
                                   when(auctionState.is("not joined"));      
       oneOf(auction).addAuctionEventListener(with(sniperForItem(itemId)));
                                   when(auctionState.is("not joined"));
       one(auction).join(); then(auctionState.is("joined"));
     }});

     launcher.joinAuction(itemId);
   }
}

Solution

I do the same exercise with Spies:

http://docs.mockito.googlecode.com/hg/latest/org/mockito/Mockito.html#13

I turned my sniperlistener simulator into a spy:

private final SniperListener sniperListenerSpy = spy(new SniperListenerStub());
private final AuctionSniper sniper = new AuctionSniper(auction,sniperListenerSpy);

A stub implementation of sniperlistener is also created:

private class SniperListenerStub implements SniperListener {
    @Override
    public void sniperLost() {
    }

    @Override
    public void sniperBidding() {
        sniperState = SniperState.bidding;
    }

    @Override
    public void sniperWinning() {
    }
}

This book uses jmock's "states", but I use a nested enumeration:

private SniperState sniperState = SniperState.idle;

private enum SniperState {
    idle,winning,bidding
}

You must then test the state using regular JUnit assertions:

@Test
public void reportsLostIfAuctionClosesWhenBidding() {
    sniper.currentPrice(123,45,PriceSource.FromOtherBidder);
    sniper.auctionClosed();
    verify(sniperListenerSpy,atLeastOnce()).sniperLost();
    assertEquals(SniperState.bidding,sniperState);
}
