### Question:
KinAccountImpl extends AbstractKinAccount { @Override public BlockchainEvents blockchainEvents() { return blockchainEvents; } KinAccountImpl(KeyPair account, BackupRestore backupRestore, TransactionSender transactionSender,
        AccountActivator accountActivator,
        AccountInfoRetriever accountInfoRetriever, BlockchainEventsCreator blockchainEventsCreator); @Override String getPublicAddress(); @NonNull @Override TransactionId sendTransactionSync(@NonNull String publicAddress, @NonNull BigDecimal amount); @NonNull @Override TransactionId sendTransactionSync(@NonNull String publicAddress, @NonNull BigDecimal amount,
        @Nullable String memo); @NonNull @Override TransactionId sendBurnAccountTransactionSync(@NonNull String publicAddress); @Override boolean isAccountBurnedSync(); @NonNull @Override Balance getBalanceSync(); @Override void activateSync(); @Override int getStatusSync(); @Override BlockchainEvents blockchainEvents(); @Override String export(@NonNull String passphrase);  }### Answer:
@Test public void createBlockchainEvents() throws Exception { initWithRandomAccount(); kinAccount.blockchainEvents(); verify(mockBlockchainEventsCreator).create(expectedRandomAccount.getAccountId()); }
