### Question:
TransactionalMessageBridge { public PutMessageResult putHalfMessage(MessageExtBrokerInner messageInner) { return store.putMessage(parseHalfMessageInner(messageInner)); } TransactionalMessageBridge(BrokerController brokerController, MessageStore store); long fetchConsumeOffset(MessageQueue mq); Set<MessageQueue> fetchMessageQueues(String topic); void updateConsumeOffset(MessageQueue mq, long offset); PullResult getHalfMessage(int queueId, long offset, int nums); PullResult getOpMessage(int queueId, long offset, int nums); PutMessageResult putHalfMessage(MessageExtBrokerInner messageInner); boolean putOpMessage(MessageExt messageExt, String opType); PutMessageResult putMessageReturnResult(MessageExtBrokerInner messageInner); boolean putMessage(MessageExtBrokerInner messageInner); MessageExtBrokerInner renewImmunityHalfMessageInner(MessageExt msgExt); MessageExtBrokerInner renewHalfMessageInner(MessageExt msgExt); MessageExt lookMessageByOffset(final long commitLogOffset); BrokerController getBrokerController();  }### Answer:
@Test public void testPutHalfMessage() { when(messageStore.putMessage(any(MessageExtBrokerInner.class))).thenReturn(new PutMessageResult (PutMessageStatus.PUT_OK, new AppendMessageResult(AppendMessageStatus.PUT_OK))); PutMessageResult result = transactionBridge.putHalfMessage(createMessageBrokerInner()); assertThat(result.getPutMessageStatus()).isEqualTo(PutMessageStatus.PUT_OK); }
