Android Can’；使用Appium网格时，不能使用2个以上的设备执行测试

背景： 我已经用Appium编写了一段时间的自动化测试脚本，大部分时间一切都很好，但是现在我尝试使用Appium网格使用多个设备执行测试，当我使用两个以上的设备执行测试时遇到了问题

问题: 使用2个以上设备时，无法使用Appium grid执行测试

我几乎可以肯定的是，问题在于节点配置，我只是尝试在线跟踪示例，但没有找到定义的任何地方，即节点配置中必需的内容

我的设置如下： 节点配置文件： 所有设备都是物理设备

我通过在4个单独的终端选项卡中执行以下命令来启动节点： 1） java-jar selenium-server-standalone-3.141.59.jar-角色中心

2） appium-p4723--nodeconfig=/LG_K11.json

3） appium-p4492--nodeconfig=/Samsung\u Tab\u S4.json

4） appium-p 8201--nodeconfig=/Samsung\u Galaxy\u S9.json

然后在IntelliJ中，我运行以下代码来初始化节点： 我只更改端口、udid和deviceName功能，并在单独的线程中运行初始化方法，然后等待它们全部完成

initDevice(String udid, int port){
    DesiredCapabilities capabilities = new DesiredCapabilities();
    capabilities.setCapability("platformName", "Android");
    capabilities.setCapability("deviceName",udid );
    capabilities.setCapability("appPackage", “xxxxxxxxx”);
    capabilities.setCapability("appActivity","MainActivity");
    capabilities.setCapability("platformName","Android");
    capabilities.setCapability("udid",udid);
    capabilities.setCapability("noReset", true);

    try {
        String appiumServerURL = String.format("http://127.0.0.1:%d/wd/hub", port);
        driver = new AndroidDriver(new URL(appiumServerURL), desiredCapabilities);
    } catch (MalformedURLException e) {
        e.printStackTrace();
    }
}

初始化后，当我尝试执行任何命令（如findElement）时，我在其中一个设备上发生崩溃：

解决了这个问题，问题是我需要传递一个引导端口，因为它们相互冲突。因此，在命令中添加了“-bp 1020x”。 之前：

之后：

appium -p 4723 -bp 10200 --nodeconfig= /LG_K11.json
