如何在ExchangeTestSupport中使用mockito

Question

我有如下的骆驼路线

public class MainRouteBuilder extends RouteBuilder {

    @Autowired
    private CcsRouteCommonProperties commonProps;

    /**
     * {@inheritDoc}
     */
    @Override
    public void configure() throws Exception {

    }
}

我已经使用ExchangeTestSupport进行了笔试，如下所示

public class MainRouteBuilderTest extends ExchangeTestSupport {

    /**
     * {@inheritDoc}
     */
    @Override
    public RoutesBuilder createRouteBuilder() throws Exception {

    }

    @Test
    public void shouldProcess() throws Exception {

    }
}

我试图嘲笑CcsRouteCommon Properties类似于下面的@Mock私有CcsRoute公益道具；

如何使用mockito（@RunWith（MockitoJUnitRunner.class））模拟上述字段

Answer 1

您的问题的直接答案是在MainRouteBuilder上使用@InjectMocks，让Mockito注入@Mock或@Spy的ccsroutcommonproperties。我希望这本简短的指南能给你解释一下。

解决方案是这样的

@RunWith(MockitoJUnitRunner.class)
    public class MainRouteBuilderTest extends ExchangeTestSupport {

        @Mock
        CcsRouteCommonProperties commonProps;

        @InjectMocks
        MainRouteBuilder routeBuilder;

        @Override
        public RoutesBuilder createRouteBuilder() throws Exception {
                return routeBuilder;
        }

        @Test
        public void shouldProcess() throws Exception {

                when(commonProps.getSomething()).thenReturn(new Something());
        }
    }

但是，如果我在你的位置上，我会避免使用@autowed魔法，并使用构造函数注入明确说明的依赖关系。

路线生成器

public class MainRouteBuilder extends RouteBuilder {
private CcsRouteCommonProperties commonProps;
    public MainRouteBuilder( CcsRouteCommonProperties commonProps) {
        this.commonProps =  commonProps;
    }
    /**
        * {@inheritDoc}
        */
    @Override
    public void configure() throws Exception {

    }
}

测验

@RunWith(MockitoJUnitRunner.class)
public class MainRouteBuilderTest extends ExchangeTestSupport {

    @Mock
    CcsRouteCommonProperties commonProps;

    @Override
    public RoutesBuilder createRouteBuilder() throws Exception {
            return new MainRouteBuilder(commonProps);
    }

    @Test
    public void shouldProcess() throws Exception {

    }
}
