### Question:
RepositoryEntityListener implements EntityListener { @Override public void onEntityId(EntityId entityId) throws ImporterException { entityRepository.insertEntityId(entityId); }  @Override boolean isEnabled(); @Override void onContractResult(ContractResult contractResult); @Override void onCryptoTransfer(CryptoTransfer cryptoTransfer); @Override void onEntityId(EntityId entityId); @Override void onFileData(FileData fileData); @Override void onLiveHash(LiveHash liveHash); @Override void onNonFeeTransfer(NonFeeTransfer nonFeeTransfer); @Override void onToken(Token token); @Override void onTokenAccount(TokenAccount tokenAccount); @Override void onTokenTransfer(TokenTransfer tokenTransfer); @Override void onTopicMessage(TopicMessage topicMessage); @Override void onTransaction(Transaction transaction);  }### Answer:
@Test void onEntityId() { repositoryEntityListener.onEntityId(ENTITY_ID); assertThat(entityRepository.findAll()).contains(ENTITY_ID.toEntity()); }
