由OSGI Felix容器初始化的模擬專用字段

Question

我試圖在我的類中模擬一個私有字段，該私有字段由運行我的應用程序的OSGI容器初始化。 我正在提供示例代碼以供參考，請提供任何線索：

import org.apache.felix.scr.annotations.*
@Component (name = "MyServiceImpl ", ds = true, immediate = true)
@Service
public class MyServiceImpl extends MyBasee implements MyService {

    @Reference (name = "MyOtherService", bind = "bind", unbind = "unbind", policy = ReferencePolicy.STATIC)
    private MyOtherService myServiceRegistryConsumer;
}

在這里，我試圖模擬私有字段MyOtherService myServiceRegistryConsumer

Answer 1

使用Mockito，您可以使用@InjectMocks批注來模擬和注入字段。

@RunWith(MockitoJUnitRunner.class)
public class AppTest {

    @Mock
    private MyOtherService myServiceRegistryConsumer;

    @InjectMocks
    private MyServiceImpl myServiceImpl;

    @Test
    public void testSomething() {
        // e.g. define behavior for the injected field
        when(myServiceRegistryConsumer.methodA()).thenReturn(/* mocked return value */);
    }
}
