### Question:
RedisMsInstService implements IMsInstService { @Override public List<TacInst> getAllTacMsInsts() { return hashOperations.values(getMainKey()); }  @Override List<TacInst> getAllTacMsInsts(); @Override TacInst getTacMsInst(Long msInstId); @Override TacInst createTacMsInst(TacInst tacInst); @Override Boolean updateTacMsInst(Long instId, TacInst tacInst); @Override Boolean removeMsInst(Long instId); @Override List<TacInst> getMsInsts(String code);  }### Answer:
@Test public void getAllTacMsInsts() { List<TacInst> allTacMsInsts = redisMsInstService.getAllTacMsInsts(); assertNotNull(allTacMsInsts); }
