匕首2:如何在JUnit测试中使用@Inject?

我希望能够用dagger2将依赖注入到JUnit测试中(我是这个框架的新手)。从春天开始,你可以这样做:

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = MyApplication.class)
public class MyTestClass {

    @Autowired
    private MyService service;

    @Test
    public void testMySerivce() { /* ... */ }

}

DaggerMyComponent.builder().build().myService()

理想情况下,我会设想如下解决方案:

// tell JUnit that dagger needs to do some post processing
@RunWith(DaggerJUnit4Runner.class)
// tell dagger which component classes to use for injection
@Components(MyComponent.class)
public class MyTestClass {

    @Inject
    private MyService service;

    @Test
    public void testMySerivce() { /* ... */ }

}

DaggerJunit4Runner .

任何关于如何做到这一点的提示都将不胜感激。
