Unit Testing Rest Controllers with @Autowired Service Class

[DJC_Spring]

Hello,

I am having problems understanding the correct way to unit test a restful controller that depends on a Autowired �Service� class. The problem I have is that when I run my unit test. I get lots of bean dependency errors that seem to go on forever. I get the feeling that I am configuring the application over again just for my unit test.

Im using @ContextConfiguation annotation in this case:

Here is my Unit Test

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration
public class RegistrationControllerTest {

	private RegistrationController registrationController;
	private MockMvc mockmvc;
	
	@Before	
	public void setUp() throws Exception {
		registrationController = new RegistrationController();
		assertThat(registrationController, notNullValue());
		
		mockmvc = MockMvcBuilders.standaloneSetup(registrationController).build();
	}

	@Test
	public void json() throws Exception {
		this.mockmvc
			.perform(post("/rest/auth/register")
			.accept(MediaType.APPLICATION_JSON).body(new String("{\"name\":springRestTest, \"user\":Darren, \"description\":Yes,it works}").getBytes()));
	}

	
}

Here is my configuration RegistrationControllerTest-context.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:mvc="http://www.springframework.org/schema/mvc"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.springframework.org/schema/beans"
	xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd
		      http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
		      http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">

	<mvc:annotation-driven />	
	<context:component-scan base-package="uk.co.myCompany.mvc" />

	<mvc:resources mapping="/resources/**" location="/resources/" />

	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/WEB-INF/views/" />
		<property name="suffix" value=".jsp" />
	</bean>

</beans>

Here is the RegistrationController

@Controller
@RequestMapping("rest/auth")
public final class RegistrationController {
	
	private static final ISaltGenerator SALT_GENERATOR = new RandomSaltGenerator();
	private static final Logger logger = Logger.getLogger(RegistrationController.class);
	
	@Autowired
	private IApplicationContextService applicationContextService;
	
	@Autowired
	private IRollupScheduleService rollupScheduleService;

	
	public RegistrationController() {
		logger.info(RegistrationController.class);
	}

My component scan picks up the controller, but then �correctly� baths because the controller needs some autowired dependencies e.g (the applicationContextService).

So what I could do is create a bean for the applicationContextService which in turn requires a DAO class to be injected. The DAO class then needs a session factory injected etc�

Is there any other quicker way to do this without having to configure the beans for the unit test. I just want to unit test the rest controller and do not need not worry about the service classes at this point.. I guess I need a way where @ContextConfiguration can kinda mock up the service classes, so I don�t have to configure them?

Is this possible or am I going about it the wrong way?

Any help would be appreciated .

Thanks
Darren.
