Inject mock services when testing a #RestController - spring

Question

I am testing a REST controller annotated with #RestController, and I'd like to inject mock services.
I am looking for help here spring boot ones but with no luck.
I am starting a test of a spring-boot application with the following annotations:
#RunWith(SpringJUnit4ClassRunner.class)
#SpringApplicationConfiguration(classes = Application.class)
#WebIntegrationTest
where Application.class is annotated with #SpringBootApplication, but it seems that I can't find a way to inject a mock dependency on my controller, for example doing this:
#Mock
private BlogPostService blogPostService;
#Before
public void setUp() throws Exception {
MockitoAnnotations.initMocks(this);
}
This is the stack trace I see, and it fails after going in timeout since it tries to inject all dependencies down to the database (the exact thing I am trying to avoid trying to introduce mocks at the services level):

Answer 1

You're using Mockito, why don't you use the Mockito test runner?
In stead of annotating your tests with the annotations you provided, use the following annotation:
#RunWith(MockitoJUnitRunner.class)
For example:
#RunWith(MockitoJUnitRunner.class)
public class MyControllerTest {
}
To inject a mock with Mockito in your controller, you use:
#RunWith(MockitoJUnitRunner.class)
public class MyControllerTest {
#InjectMocks
private MyController controller;
#Mock
private BlogPostService service;
}
In this case Mockito will create a new instance of MyController (your REST controller) and inject a mock of type BlogPostService in all fields of your controller with the given field.
The annotations you provided are great for integration testing, but you don't need them when you're testing your controller as a unit.
And if you're integration testing, mocking a service isn't right either.
