### Question:
BlockingTrezorClient implements TrezorClient { @Override public void connect() { trezor.connect(); isTrezorValid = true; } protected  BlockingTrezorClient(Trezor trezor, ByteString sessionId); @Override void connect(); @Override void close(); TrezorEvent ping(); TrezorEvent initialize(); TrezorEvent getUUID(); TrezorEvent optAck(char[] oneTimePassword); TrezorEvent optCancel(); TrezorEvent pinAck(char[] pin); TrezorEvent pinCancel(); TrezorEvent getEntropy(); TrezorEvent setMaxFeeKb(long satoshisPerKb); TrezorEvent getMasterPublicKey(); TrezorEvent getAddress(int index, int value); TrezorEvent loadDevice(
    TrezorMessage.Algorithm algorithm,
    char[] seed,
    boolean useOtp,
    byte[] pin,
    boolean useSpv); TrezorEvent resetDevice(
    byte[] entropy); Optional<Transaction> signTx(Transaction tx); void secureErase(char[] value); void secureErase(byte[] value); byte[] newEntropy(int size); @Override BlockingQueue<TrezorEvent> getTrezorEventQueue(); @Override void setTrezorEventQueue(BlockingQueue<TrezorEvent> trezorEventQueue);  }### Answer:
@Test public void testConnect() throws Exception { ByteString sessionId = TrezorClients.newSessionId(); BlockingTrezorClient testObject = TrezorClients.newBlockingSocketInstance( "localhost", 3000, sessionId ); TrezorEmulator emulator = TrezorEmulator.newDefaultTrezorEmulator(); emulator.start(); testObject.connect(); TrezorEvent event1 = testObject.getTrezorEventQueue().poll(1, TimeUnit.SECONDS); assertThat(event1).isNotNull(); assertThat(event1.protocolMessageType().isPresent()).isFalse(); assertThat(event1.eventType()).isEqualTo(TrezorEventType.DEVICE_CONNECTED); TrezorEvent event2 = testObject.getTrezorEventQueue().poll(1, TimeUnit.SECONDS); assertThat(event2).isNotNull(); assertThat(event2.protocolMessageType().isPresent()).isTrue(); assertThat(event2.protocolMessageType().get()).isEqualTo(MessageType.SUCCESS); testObject.close(); }
