### Question:
StandaloneHerder extends AbstractHerder { @Override public void putTaskConfigs(String connName, List<Map<String, String>> configs, Callback<Void> callback) { throw new UnsupportedOperationException("Kafka Connect in standalone mode does not support externally setting task configurations."); } StandaloneHerder(Worker worker);   StandaloneHerder(Worker worker,
                     String workerId,
                     StatusBackingStore statusBackingStore,
                     MemoryConfigBackingStore configBackingStore); synchronized void start(); synchronized void stop(); @Override int generation(); @Override synchronized void connectors(Callback<Collection<String>> callback); @Override synchronized void connectorInfo(String connName, Callback<ConnectorInfo> callback); @Override void connectorConfig(String connName, final Callback<Map<String, String>> callback); @Override synchronized void deleteConnectorConfig(String connName, Callback<Created<ConnectorInfo>> callback); @Override synchronized void putConnectorConfig(String connName,
                                                final Map<String, String> config,
                                                boolean allowReplace,
                                                final Callback<Created<ConnectorInfo>> callback); @Override synchronized void requestTaskReconfiguration(String connName); @Override synchronized void taskConfigs(String connName, Callback<List<TaskInfo>> callback); @Override void putTaskConfigs(String connName, List<Map<String, String>> configs, Callback<Void> callback); @Override synchronized void restartTask(ConnectorTaskId taskId, Callback<Void> cb); @Override synchronized void restartConnector(String connName, Callback<Void> cb);  }### Answer:
@Test(expected = UnsupportedOperationException.class) public void testPutTaskConfigs() { Callback<Void> cb = PowerMock.createMock(Callback.class); PowerMock.replayAll(); herder.putTaskConfigs(CONNECTOR_NAME, Arrays.asList(singletonMap("config", "value")), cb); PowerMock.verifyAll(); }
