Question

我是EasyMock的新手并在我的项目中实现了JUnits。下面是我的Test类，通过查看代码，你可以理解我在这里做什么。我正在使用EasyMock 3.4。

简而言之：我正在为我的实际方法FmrTradeConsumerImpl.onTODEvent(TodEvents todEvents)编写一个Junit。

myTestClass：

@RunWith(EasyMockRunner.class)
public class FmrTradeConsumerImplTest extends EasyMockSupport {

    @TestSubject
    private FmrTradeConsumerImpl fmrTradeConsumer = new FmrTradeConsumerImpl();
    @Mock
    private TradeService tradeService;
    @Mock
    private TradeIvTypeValidator tradeValid;
    @Mock
    private TodEvents todEvents;

    private List<TradeDetails> tradesList;
    private SecurityTradeExecution tradeEx;
    private List<SecurityTradeExecution> securityTradeEx;

    @Before
    public void init() {

        tradeService = niceMock(TradeService.class);
        todEvents = niceMock(TodEvents.class);
        securityTradeEx = new ArrayList<>();
        tradesList = new ArrayList<>();
        tradeEx = new SecurityTradeExecution();
        tradeValid = niceMock(TradeIvTypeValidator.class);
        resetAll();
    }

    @Test
    public void onTODEvent() {
        tradeEx.setFundNumber(Long.valueOf("2016"));
        tradeEx.setSourceSystemCd("AIM");
        tradeEx.setIvType("Test");
        securityTradeEx.add(tradeEx);

         expect(todEvents.getSecurityTradeExcecutions()).andReturn(securityTradeEx);
        expect(tradeValid.isValidIvType("Test")).andReturn(true);

        tradeService.saveTradeRecordsListAsBatch(tradesList);
        expectLastCall().andVoid();

        replayAll();

        fmrTradeConsumer.onTODEvent(todEvents);
    }
}

我收到了以下错误：

请提供您的建议，非常感谢你。

Answer 1

不使用“私有TradeIvTypeValidator tradeValid;”的“@Mock”注释，而是使用“@NiceMock”。这里NiceMock提供默认实现，如果你使用“@Mock”，那么它可以让开发人员做同样的事情

Answer 2

为什么要在创建后重置所有模拟？你可以删除该行并尝试它是否有效

EasyMock：AssertionError - 意外的方法调用：具有多个模拟对象的多个expecations
