### Question:
GoogleAppsSdkUtils { public static com.google.api.services.groupssettings.model.Groups retrieveGroupSettings(Groupssettings groupssettingClient, String groupKey) throws IOException { LOG.debug("retrieveGroupssettings() - {}", groupKey); Groupssettings.Groups.Get request = null; try { request = groupssettingClient.groups().get(groupKey); } catch (IOException e) { LOG.error("An unknown error occurred: " + e); } return (com.google.api.services.groupssettings.model.Groups) execute(request); }  static GoogleCredential getGoogleDirectoryCredential(String serviceAccountEmail, String serviceAccountPKCS12FilePath,
                                                                String serviceAccountUser, HttpTransport httpTransport, JsonFactory jsonFactory); static GoogleCredential getGoogleDirectoryCredential(String serviceAccountEmail, String serviceAccountPKCS12FilePath,

@Test public void testRetrieveGroupSettings() throws GeneralSecurityException, IOException { com.google.api.services.groupssettings.model.Groups groupsSettings = GoogleAppsSdkUtils.retrieveGroupSettings(groupssettingsClient, TEST_GROUP); assertEquals("Test Group", groupsSettings.getName()); }
