The code to perform integration testing on the created todo in TodoController is shown as follows. This would be added to the TodoControllerIT class, as follows:

    @Test
    public void addTodo() throws Exception {
      Todo todo = new Todo(-1, "Jill", "Learn Hibernate", new Date(),  
      false);
      URI location = template
     .postForLocation(createUrl("/users/Jill/todos"),todo);
      assertThat(location.getPath(), 
      containsString("/users/Jill/todos/4"));
    }

A few important things to note are as follows:

• URI location = template.postForLocation(createUrl("/users/Jill/todos"), todo): postForLocation is a utility method especially useful in tests to create new resources. We are posting the todo to the given URI and getting the location from the header.
• assertThat(location.getPath(), containsString("/users/Jill/todos/4")): Asserts that the location contains the path to the newly created resource.
