### Question:
ApimAdapterService implements Closeable { public AuthRepResponse authRepWithClientId(String realm, String clientId, String path, String queryString, HttpMethod method) { if (path == null || method == null) { LOG.warn(APIM_2033.pattern(), path, method); return errorResponseHelper.createErrorAuthResponse(realm, clientId, BAD_REQUEST, path, queryString, method, emptyList()); } final MetricMatchingResult metricMatchingResult = matchMetric(path, method, queryString); if (clientId == null || clientId.isEmpty()) { LOG.warn(APIM_2034.pattern()); return errorResponseHelper.createErrorAuthResponse(realm, clientId, UNAUTHORIZED, path, queryString, method, metricMatchingResult.getMetricSystemNames()); } final Client client = clientCache.get(clientId); if (!client.isAppWithPermission()) { return errorResponseHelper.createErrorAuthResponse(realm, clientId, CLIENT_ID_HAS_NO_PERMISSION, path, queryString, method, metricMatchingResult.getMetricSystemNames()); } if (metricMatchingResult.getMatchingPathMetrics().isEmpty()) { return errorResponseHelper.createErrorAuthResponse(realm, clientId, PATH_NOT_FOUND, path, queryString, method, metricMatchingResult.getMetricSystemNames()); } if (metricMatchingResult.getMetricSystemNames().isEmpty()) { return errorResponseHelper.createErrorAuthResponse(realm, clientId, METHOD_NOT_FOUND, path, queryString, method, metricMatchingResult.getMetricSystemNames()); } if (!incrementUsages(client, metricMatchingResult.getMetricSystemNames())) { return errorResponseHelper.createErrorAuthResponse(realm, clientId, LIMIT_EXCEEDED, path, queryString, method, metricMatchingResult.getMetricSystemNames()); } return new AuthRepResponse(true, clientId, SC_OK, metricMatchingResult.getMetricSystemNames(), "Access granted and reporting reported.", path, queryString, method); } ApimAdapterService(

@Test public void testAccessWithClientIdOnly() { try (ApimAdapterService service = ApimAdapterFactory.createApimAdapterService()) { HttpMethod method = GET; AuthRepResponse authRepResponse = service.authRepWithClientId(AuthUtils.RH_SSO_REALM, CLIENT_ID, V1_LOCATIONS, "", method); assertTrue(authRepResponse.isAllowed()); assertEquals(authRepResponse.getClientId(), CLIENT_ID); assertNotNull(authRepResponse.getMessage()); } }
