Tengo la aplicación SpringBoot ordinaria con filtro de autenticación personalizado que funciona normalmente.

Pero tengo un problema al usar TestRestTemplate en la prueba de integración.

Me gustaría verificar aquí si el usuario con créditos incorrectos no puede iniciar sesión. Pero en lugar de ResponseEntity con el estado 401 obtuve la excepción:

Internamente, spring produce org.springframework.security.authentication.BadCredentialsException, pero en el uso de aplicaciones reales se traduce en respuesta json.

Cuando uso curl obtuve una respuesta normal.

curl -H "Content-Type: application/json" -d '{"name":"user","password":"password-wrong"}' http://localhost:8080/login
{"timestamp":"2014-12-07T10:07:27.166+0000","status":401,"error":"Unauthorized","exception":"org.springframework.security.authentication.BadCredentialsException","message":"Bad credentials","path":"/login"}

El código de prueba está aquí:

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Application.class)
@WebAppConfiguration
@IntegrationTest("server.port:9999")
public class AuthorizeControllerTest {

  public static final String LOCALHOST = "http://localhost:9999";

...

  @Test
  public void userWithWrongCreditials() throws Exception {
    RestTemplate rest = new TestRestTemplate();

    Credentials credentials = new Credentials();
    credentials.setName("user");
    credentials.setPassword("password-wrong");

    ResponseEntity<Map> response =
      rest.exchange(
        LOCALHOST + "/login",
        HttpMethod.POST,
        new HttpEntity<Credentials>(credentials),
        Map.class);

    assertEquals(HttpStatus.UNAUTHORIZED, response.getStatusCode());
  }
}

Todo el proyecto se puede ver en el repositorio

https://bitbucket.org/winsik/security-token-stackoverflow/

Donde puede ver tanto las pruebas aprobadas como las reprobadas en AuthorizeControllerTest.

He intentado muchas cosas, como configurar el tipo de contenido, etc., pero sin suerte. Agradecería cualquier idea.
