运行后，验证了两个地址都正常返回： http://127.0.0.1:4723/ 与 http://127.0.0.1:4725/
对两台测试设备进行测试，一台测试设备为 Android 设备，一台为 iOS 设备，类似用 iPhone 充当遥控器控制一台 Android 盒子。
因为手上暂时并没有 mac 环境，暂时用两台 Android 设备测试。
电脑开启两个 Appium 客户端，将其中一个客户端的端口改为：4725

测试设备：
被测程序在一台机器（deviceName=0123456789ABCDEF）启动了两次，而另外一台机器没有任何执行。
Appium 日志：
4723 端口的 Appium 服务端的日志中，deviceName 从 b1d12c6 变成了 0123456789ABCDEF

.......之后所有的日志中的 deviceName 全部为 0123456789ABCDEF
从现象上看，好像是 client 发送的 json 信息中 deviceName 确实是 b1d12c6，但是 Appium 在执行时，将 deviceid 设置成了另一台的测试设备的 deviceName 0123456789ABCDEF
导致设备 0123456789ABCDEF 上运行了两次脚本
是 Appium 本身不支持电脑运行多个服务端？还是我 client 的 bug？
两台电脑分别运行 Appium 服务端，端口的 ip 改为电脑真实的 ip，然后通过脚本操作两个 Appium 服务端分别控制两个测试设备，这样是 OK 的。但是平白多浪费一台电脑，感觉实在有点浪费。
设置 udid
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("device","Android");
capabilities.setCapability("deviceName", "b1d12c6");
capabilities.setCapability("udid", "b1d12c6");
capabilities.setCapability("platformVersion", "4.4.4");
capabilities.setCapability("platformName", "Android");
capabilities.setCapability("appPackage", "com.runmit.sweedee");
capabilities.setCapability("appActivity", "com.runmit.sweedee.LoadingActivity");
driver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);
DesiredCapabilities capabilities2 = new DesiredCapabilities();
capabilities2.setCapability("device","Android");
capabilities2.setCapability("deviceName", "0123456789ABCDEF");
capabilities2.setCapability("udid", "0123456789ABCDEF");
capabilities2.setCapability("platformVersion", "4.4.4");
capabilities2.setCapability("platformName", "Android");
capabilities2.setCapability("appPackage", "com.runmit.sweedee");
capabilities2.setCapability("appActivity", "com.runmit.sweedee.LoadingActivity");
driver2 = new AndroidDriver(new URL("http://127.0.0.1:4725/wd/hub"), capabilities2);
之后同时启动成功
