“面向对象软件”这本书在jMock中提供了几个例子,其中状态是显式的,而不会通过API暴露.我真的很喜欢这个想法.有没有办法在Mockito这样做？
这是这本书的一个例子
@H_403_4@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); } }解决方法
我用间谍进行自我相同的练习：
http://docs.mockito.googlecode.com/hg/latest/org/mockito/Mockito.html#13
我把我的SniperListener模拟器变成一个间谍：
@H_403_4@private final SniperListener sniperListenerSpy = spy(new SniperListenerStub()); private final AuctionSniper sniper = new AuctionSniper(auction,sniperListenerSpy);并且还创建了SniperListener的一个stubbed实现：
@H_403_4@private class SniperListenerStub implements SniperListener { @Override public void sniperLost() { } @Override public void sniperBidding() { sniperState = SniperState.bidding; } @Override public void sniperWinning() { } }这本书使用JMock的“States”,但是我使用了一个嵌套的枚举：
@H_403_4@private SniperState sniperState = SniperState.idle; private enum SniperState { idle,winning,bidding }然后,您必须使用常规JUnit断言来测试状态：
@H_403_4@@Test public void reportsLostIfAuctionClosesWhenBidding() { sniper.currentPrice(123,45,PriceSource.FromOtherBidder); sniper.auctionClosed(); verify(sniperListenerSpy,atLeastOnce()).sniperLost(); assertEquals(SniperState.bidding,sniperState); }
