Unit test of rest mvc

[lg.lindstrom]

Hi

A question about how to use test-mvc for unit testing.

I have a simple controller..

	@Controller
	@RequestMapping("/users")
	public class UserController {		 
		private UserService business;
		@Autowired
		public UserController(UserService bus)
		{
			business = bus;
		}
		@RequestMapping(value="{id}", method = RequestMethod.GET)
		public @ResponseBody User getUserById(@PathVariable String id) throws ItemNotFoundException{
 		
			return business.GetUserById(id);
	 
		}

My idea is to keep the controllers so thin as possible.

To test this controller I am trying to do something like this.

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath:mvc-dispatcher-servlet.xml"})
public class UserControllerTest extends ControllerTestBase {

	UserService mockedService;
	
	@Before
	public void Setup()
	{
		
		MockitoAnnotations.initMocks( this );	
		mockedService = mock(UserService.class);
	    
	}
		
	@Test
	public void ReturnUserById() throws Exception{
				 
		User user = new User();
		user.setName("Lasse");
		
		stub(mockedService.GetUserById("lasse")).toReturn(user);
	 		
		MockMvcBuilders.standaloneSetup(new UserController(mockedService)).build()
    	.perform(get("/users/lasse"))
        .andExpect(status().isOk())
        .andExpect(?????????????????????????????);
		
	}

My intention is to check that proper json code is returned,,,,,,

I am not a pro,,, so I have not found a way to replace ??????????????????????? to do verify the returned string but I am certain that there must be a elegant way to do this

Can anyone fill me in?

Based on the Spring MVC Test github, I would try something like:

MockMvcBuilders.annotationConfigSetup(TestConfiguration.class).build()
    .perform(get("/resources/Spring.js"))
        .andExpect(content().type("application/octet-stream"))
        .andExpect(content().string(containsString("Spring={};")));

Besides Spring MVC Test there is a other possibility, you could use Arquillian Spring Framework Extension in order to test your REST services. Arquillian is a integration test framework that executes your tests in real servlet container like Glassfish or JBoss AS. So you could be able to run your tests against executing application.
