### Question:
RestUserController { @ResponseStatus(HttpStatus.NO_CONTENT) @RequestMapping(value = "/users/{$username}", method = RequestMethod.DELETE) public void delete(@PathVariable("$username") String username) throws UserException { final User user = userService.findByUsername(username); if (user == null ) { throw new UserException("No user found for username " + username); } userService.deleteById(user.getId()); } @Autowired  RestUserController(UserService userService); @RequestMapping(value = "/users", method = RequestMethod.GET) List<User> all(); @ResponseStatus(HttpStatus.CREATED) @RequestMapping(value = "/users", method = RequestMethod.POST) void create(
            @RequestBody @Valid User newUser,
            @Value("#{request.requestURL}")
            StringBuffer originalUrl,
            HttpServletResponse response); @ResponseStatus(HttpStatus.OK) @RequestMapping(value = "/users/{$username}", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_UTF8_VALUE) User getByUsername(@PathVariable("$username") String username); @ResponseStatus(HttpStatus.OK) @RequestMapping(value = "/users/{$username}", method = RequestMethod.PUT, produces = MediaType.APPLICATION_JSON_VALUE) User update(@PathVariable("$username") String username, @RequestBody User newUser); @ResponseStatus(HttpStatus.NO_CONTENT) @RequestMapping(value = "/users/{$username}", method = RequestMethod.DELETE) void delete(@PathVariable("$username") String username); @ResponseStatus(HttpStatus.OK) @RequestMapping(value = "/allusers/{$type}", produces = MediaType.APPLICATION_JSON_VALUE) Collection<User> getByType(@PathVariable("$type") UserType type); @ResponseStatus(HttpStatus.OK) @RequestMapping(value = "/emails/{$type}", produces = MediaType.APPLICATION_JSON_VALUE) Collection<String> getIdsByType(@PathVariable("$type") UserType type); @ResponseStatus(HttpStatus.NOT_FOUND) @ExceptionHandler({IllegalArgumentException.class}) void handleNotFound(); @ResponseStatus(HttpStatus.CONFLICT) @ExceptionHandler({DataIntegrityViolationException.class}) void handleAlreadyExists();  }### Answer:
@Test public void deleteUser() { restTemplate.delete(GET_PUT_DEL_URL, "gigipedala"); final User newUser = restTemplate.getForObject(GET_PUT_DEL_URL, User.class, "gigipedala"); assertNull(newUser); }
