### Question:
ConsumerStatusSubCommand implements SubCommand { @Override public void execute(CommandLine commandLine, Options options, RPCHook rpcHook) { DefaultMQAdminExt defaultMQAdminExt = new DefaultMQAdminExt(rpcHook); defaultMQAdminExt.setInstanceName(Long.toString(System.currentTimeMillis())); try { defaultMQAdminExt.start(); String group = commandLine.getOptionValue('g').trim(); ConsumerConnection cc = defaultMQAdminExt.examineConsumerConnectionInfo(group); boolean jstack = commandLine.hasOption('s'); if (!commandLine.hasOption('i')) { int i = 1; long now = System.currentTimeMillis(); final TreeMap<String, ConsumerRunningInfo> criTable = new TreeMap<String, ConsumerRunningInfo>(); for (Connection conn : cc.getConnectionSet()) { try { ConsumerRunningInfo consumerRunningInfo = defaultMQAdminExt.getConsumerRunningInfo(group, conn.getClientId(), jstack); if (consumerRunningInfo != null) { criTable.put(conn.getClientId(), consumerRunningInfo); String filePath = now + "/" + conn.getClientId(); MixAll.string2FileNotSafe(consumerRunningInfo.formatString(), filePath); System.out.printf("%03d %-40s %-20s %s%n", i++, conn.getClientId(), MQVersion.getVersionDesc(conn.getVersion()), filePath); } } catch (Exception e) { e.printStackTrace(); } } if (!criTable.isEmpty()) { boolean subSame = ConsumerRunningInfo.analyzeSubscription(criTable); boolean rebalanceOK = subSame && ConsumerRunningInfo.analyzeRebalance(criTable); if (subSame) { System.out.printf("%n%nSame subscription in the same group of consumer"); System.out.printf("%n%nRebalance %s%n", rebalanceOK ? "OK" : "Failed"); Iterator<Entry<String, ConsumerRunningInfo>> it = criTable.entrySet().iterator(); while (it.hasNext()) { Entry<String, ConsumerRunningInfo> next = it.next(); String result = ConsumerRunningInfo.analyzeProcessQueue(next.getKey(), next.getValue()); if (result.length() > 0) { System.out.printf(result); } } } else { System.out.printf("%n%nWARN: Different subscription in the same group of consumer!!!"); } } } else { String clientId = commandLine.getOptionValue('i').trim(); ConsumerRunningInfo consumerRunningInfo = defaultMQAdminExt.getConsumerRunningInfo(group, clientId, jstack); if (consumerRunningInfo != null) { System.out.printf("%s", consumerRunningInfo.formatString()); } } } catch (Exception e) { e.printStackTrace(); } finally { defaultMQAdminExt.shutdown(); } }  static void main(String[] args); @Override String commandName(); @Override String commandDesc(); @Override Options buildCommandlineOptions(Options options); @Override void execute(CommandLine commandLine, Options options, RPCHook rpcHook);  }### Answer:
@Test public void testExecute() { ConsumerStatusSubCommand cmd = new ConsumerStatusSubCommand(); Options options = ServerUtil.buildCommandlineOptions(new Options()); String[] subargs = new String[] {"-g default-group", "-i cid_one"}; final CommandLine commandLine = ServerUtil.parseCmdLine("mqadmin " + cmd.commandName(), subargs, cmd.buildCommandlineOptions(options), new PosixParser()); cmd.execute(commandLine, options, null); }
