The code to perform integration testing on the TodoController class is shown in the following code snippet. It launches up the entire Spring context with all the controllers and beans defined:

   @RunWith(SpringJUnit4ClassRunner.class)
   @SpringBootTest(classes = Application.class, webEnvironment =     
   SpringBootTest.WebEnvironment.RANDOM_PORT)
   public class TodoControllerIT {

    @LocalServerPort
    private int port;

    private TestRestTemplate template = new TestRestTemplate();

    @Test
    public void retrieveTodos() throws Exception {
     String expected = "["
     + "{id:1,user:Jack,desc:"Learn Spring MVC",done:false}" + ","
     + "{id:2,user:Jack,desc:"Learn Struts",done:false}" + "]";

     String uri = "/users/Jack/todos";

     ResponseEntity<String> response =
     template.getForEntity(createUrl(uri), String.class);

     JSONAssert.assertEquals(expected, response.getBody(), false);
    }

     private String createUrl(String uri) {
     return "http://localhost:" + port + uri;
    }
  }

This test is very similar to the integration test for BasicController, except that we are using JSONAssert to assert the response.
