Spring Boot Unit Test - Missing beans running test

Question

Spring Boot version 1.5.4.RELEASE.

Running the application normal works fine.

When running a Unit test, some beans are missing, for example:

***************************
APPLICATION FAILED TO START
***************************

Description:

Parameter 0 of constructor in ...service.post.PostService required a bean named 'mongoTemplate' that could not be found.


Action:

Consider defining a bean named 'mongoTemplate' in your configuration.

I'm using a MongoDB repository. I solved this by adding a config class which returns this bean.

After this I tried to execute the Unit test again, the following error came up:

***************************
APPLICATION FAILED TO START
***************************

Description:

Parameter 0 of constructor in springfox.documentation.spring.data.rest.BasePathAwareServicesProvider required a bean of type 'org.springframework.data.rest.core.config.RepositoryRestConfiguration' that could not be found.


Action:

Consider defining a bean of type 'org.springframework.data.rest.core.config.RepositoryRestConfiguration' in your configuration.

This is raised by the springfox swagger ui Rest documentation. When removing this application dependency, the test completes successfully.

What did I miss here? Some beans cannot be found or auto configured in the Unit test 'environment'.

Update

@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class)
public class ApplicationTests {

    @Test
    public void contextLoads() {}
}

@RunWith(SpringRunner.class)
@WebMvcTest(value = ProfileController.class, secure = false)
public class ProfileControllerTest {
    private MockMvc mockMvc;
    @MockBean private ProfileService profileService;

    @Before
    public void setUp() {
        this.mockMvc = MockMvcBuilders.standaloneSetup(new ProfileController(profileService)).build();
    }

    @Test
    ....
}

This is the only test controller I currently have.

Modifying your code to show how to exclude a configuration that is usually required when running Unit tests:

@RunWith(SpringRunner.class)
@SpringBootTest(classes = Application.class)
public class ApplicationTests {

    @Test
    public void contextLoads() {}
}

@RunWith(SpringRunner.class)
@WebMvcTest(value = ProfileController.class, secure = false, excludeAutoConfiguration = EmbeddedMongoAutoConfiguration.class) // or any other configuration.
public class ProfileControllerTest {
    private MockMvc mockMvc;
    @MockBean private ProfileService profileService;

    @Before
    public void setUp() {
        this.mockMvc = MockMvcBuilders.standaloneSetup(new ProfileController(profileService)).build();
}

@Test
....

}
