java - 如何创建 "deep"模拟 spring bean？

Question

我有一个这样的 Spring Bean

@Component
public class Service extends AbstractService {
        @Autowired
        private OtherService otherService;
}

为了测试，我用 Service mock 创建了一个测试上下文

<bean id="serviceMock" class="org.easymock.EasyMock" factory-method="createMock"  primary="true">
    <constructor-arg index="0" type="java.lang.Class" value="com.pkg.my.Service"/>
</bean>

模拟仍然需要我模拟所有 Autowiring 的依赖项。有没有办法只创建“哑”模拟而不需要为所有依赖项创建 bean？

您的单元测试需要依赖注入(inject)吗？

我更喜欢 setter 注入(inject)，因为这样你就不需要初始化 Spring Framework。例如:

@Component
public class Service extends AbstractService {
    private OtherService otherService;

    @Autowired
    public void setOtherService(OtherService otherService){...}
}

然后在你的测试类上:

public class ServiceTest {

    private Service service;

    private OtherService otherServiceMock;

    @Before
    public void setUp() {
        otherServiceMock= mock(OtherService.class);
        service = new Service();
        service.setOtherService(otherServiceMock);
    }

    @Test
    public void testSomeMethodBlaBla(){...}
}
