Authentication role

I test my Controller with Mockito. test my method in controller:

@RequestMapping("/dispatcher")
    public String disp(final HttpServletRequest request) {
        if (request.isUserInRole("USER")) {
            return "hello";
        } else if (request.isUserInRole("ADMIN")) {
            return "redirect:listUsers.htm";
        }
        throw new RuntimeException("This role is not registrated");
    }

My test method:

@Test

    public void testDispatcher() throws Exception {
    User user = userDao.findByLogin("log1");
    TestingAuthenticationToken testingAuthenticationToken = new TestingAuthenticationToken(user, AuthorityUtils.createAuthorityList("USER"));  
              SecurityContextHolder.getContext().setAuthentication(testingAuthenticationToken);
                System.out.println(testingAuthenticationToken);
                mockMvc.perform(post("/dispatcher")
                        .principal(testingAuthenticationToken))
                        .andExpect(status().isOk());
}

Error: org.springframework.security.authentication.TestingAuthenticationToken@bf72b5bd: Principal: User [id=1, firstName=name1, lastName=surname1, login=log1, email=email1@gmail.com, password=psw1, birthDate=1980-01-01 00:00:00.0, role=[id=1, name=USER]]; Credentials: [PROTECTED]; Authenticated: false; Details: null; Not granted any authorities

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.RuntimeException: This role is not registrated

How i can set Role for method request.isUserInRole(); or maybe has another solution to my issue
