### Question:
FabricTopicAdmin implements IEventTopic { @Override public GroupGeneral getGroupGeneral(String channelName) throws BrokerException { validateChannelName(channelName); return fabricDelegate.getFabricMap().get(channelName).getGroupGeneral(); } FabricTopicAdmin(FabricDelegate fabricDelegate); @Override boolean open(String topic, String channelName); @Override boolean close(String topic, String channelName); @Override WeEvent getEvent(String eventId, String channelName); @Override boolean exist(String topic, String channelName); @Override TopicPage list(Integer pageIndex, Integer pageSize, String channelName); @Override TopicInfo state(String topic, String channelName); @Override List<String> listGroupId(); @Override Long getBlockHeight(String channelName); @Override GroupGeneral getGroupGeneral(String channelName); @Override ListPage<TbTransHash> queryTransList(QueryEntity queryEntity); @Override ListPage<TbBlock> queryBlockList(QueryEntity queryEntity); @Override ListPage<TbNode> queryNodeList(QueryEntity queryEntity); @Override ContractContext getContractContext(String groupId); @Override boolean addOperator(String groupId, String topicName, String address); @Override boolean delOperator(String groupId, String topicName, String address); @Override List<String> listOperator(String groupId, String topicName); @Override void validateGroupId(String channelName);  }### Answer:
@Test public void testGetGroupGeneral() throws BrokerException { GroupGeneral groupGeneral = this.iProducer.getGroupGeneral(this.channelName); Assert.assertNotNull(groupGeneral); Assert.assertNotNull(groupGeneral.getLatestBlock()); Assert.assertNotNull(groupGeneral.getTransactionCount()); }
