使用Appium网格时,无法使用2个以上的设备执行测试

篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了使用Appium网格时,无法使用2个以上的设备执行测试相关的知识,希望对你有一定的参考价值。

上下文:我一直在用Appium编写自动化测试脚本很长一段时间,一切都运行良好,但现在我正在尝试使用Appium网格执行多个设备的测试,而我在执行时遇到问题测试超过2个设备。

问题:使用2个以上的设备时,无法使用Appium网格执行测试。

我几乎可以肯定,问题在于节点配置,我只是尝试在线跟踪示例,但没有找到任何定义,节点配置中的强制性。

我的设置是这样的:节点配置文件:所有设备都是物理的

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 -role hub

2)appium = -p 4723 --nodeconfig /LG_K11.json

3)appium = -p 4492 --nodeconfig /Samsung_Tab_S4.json

4)appium = -p 8201 --nodeconfig /Samsung_Galaxy_S9.json

然后在IntelliJ中运行此代码以初始化节点:我只更改ports,udid和deviceName功能,并在单独的线程中运行初始化方法,并等待所有这些完成。

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();
    }
}

在初始化之后,当我尝试执行任何命令(例如findElement)时,我在其中一个设备上遇到此崩溃:

答案

解决了它,问题是我需要通过一个bootstrap端口,因为它们是冲突的。所以在命令中添加了“-bp 1020x”。之前:

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

后:

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