c++ – there is a bug test in webrtc thread_unittest.cc?

code as below:

TEST(ThreadTest, DISABLED_Main) {
  const SocketAddress addr("127.0.0.1", 0);

  // Create the messaging client on its own thread.
  auto th1 = Thread::CreateWithSocketServer();
  Socket* socket =
      th1->socketserver()->CreateAsyncSocket(addr.family(), SOCK_DGRAM);
  MessageClient msg_client(th1.get(), socket);

  // Create the socket client on its own thread.
  auto th2 = Thread::CreateWithSocketServer();
  AsyncSocket* asocket =
      th2->socketserver()->CreateAsyncSocket(addr.family(), SOCK_DGRAM);
  SocketClient sock_client(asocket, addr, th1.get(), &msg_client);

  socket->Connect(sock_client.address());

  th1->Start();
  th2->Start();

  // Get the messages started.
  th1->PostDelayed(RTC_FROM_HERE, 100, &msg_client, 0, new TestMessage(1));

  // Give the clients a little while to run.
  // Messages will be processed at 100, 300, 500, 700, 900.
  Thread* th_main = Thread::Current();
  th_main->ProcessMessages(1000);

  // Stop the sending client. Give the receiver a bit longer to run, in case
  // it is running on a machine that is under load (e.g. the build machine).
  th1->Stop();
  th_main->ProcessMessages(200);
  th2->Stop();

  // Make sure the results were correct
  EXPECT_EQ(5, msg_client.count);
  EXPECT_EQ(34, msg_client.last);
  EXPECT_EQ(5, sock_client.count);
  EXPECT_EQ(55, sock_client.last);
}

my question is socket call Connect，i think it will fail, beacause i found there is no any server which address is 127.0.0.1 and any port is created, is that right?
