模拟由 OSGI Felix 容器初始化的私有字段

Question

我正在尝试在我的类中模拟一个私有字段，该字段正在由运行我的应用程序的 OSGI 容器初始化。我放了一个示例代码供参考，请提供任何线索：

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;
}

这里我试图模拟私有字段MyOtherService myServiceRegistryConsumer

Answer 1

借助 Mockito，您可以使用 @InjectMocksannotation 模拟和注入字段。

@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 */);
    }
}
