Let's shift our focus to writing an integration test. Let's add a method to BasicControllerIT, as shown in the following code snippet:

    @Test
    public void welcomeWithObject() throws Exception {
      ResponseEntity<String> response = 
      template.getForEntity(createURL("/welcome-with-object"), 
      String.class);
      assertThat(response.getBody(), 
      containsString("Hello World"));
    }

This method is similar to the earlier integration test except that we are asserting for a sub-string using the String method.
