 * Trait for ResourceTestBase subclasses testing $auth=basic_auth.

 * Characteristics:
 * - Every request must send an Authorization header.
 * - When accessing a URI that requires authentication without being
 *   authenticated, a 401 response must be sent.
 * - Because every request must send an authorization, there is no danger of
 *   CSRF attacks.
