### Question:
RedisMsService implements IMsService { @Override public TacMsDO createMs(TacMsDO tacMsDO) { checkMsDO(tacMsDO); hashOperations.put(getMainKey(), tacMsDO.getCode(), tacMsDO); return tacMsDO; }  @Override TacMsDO createMs(TacMsDO tacMsDO); @Override Boolean removeMs(String msCode); @Override Boolean invalidMs(String msCode); @Override Boolean updateMs(String msCode, TacMsDO tacMsDO); @Override TacMsDO getMs(String msCode); @Override List<TacMsDO> getAllMs();  }### Answer:
@Test public void createMs() { redisMsService.createMs(tacMsDO); TacMsDO ms = redisMsService.getMs(tacMsDO.getCode()); assertNotNull(ms); }
