@Test
public void showProject_shouldReturnAccessDenied_forUnauthenticatedUser() {
    // Given an unauthenticated get project request
    HttpEntity request = unauthenticatedRequest("GET /projects/1");

    ResponseEntity<ErrorResponse> response = handleRequest(request);

    // Then a forbidden response should be returned
