间歇出现的Appium未知服务器端错误

Question

我似乎间歇性地遇到了这个问题。如果我要拔出并重新插入设备并重新启动测试，则没有错误，但这只是暂时性的修复，直到它再次出现为止。我有2个设备的appium服务器的2个实例-

server1
Host-0.0.0.0
server port-5050
Bootstrap port- 4734
allow session overrides- ticked

server2
Host-0.0.0.0
server port-4723
Bootstrap port- 4724
allow session overrides- ticked

appium版本-1.15.1

List of devices attached-
52002dd24392b5a1        device
5200472dec01a4a9        device

appium服务器控制台上的错误-

device1-所需的功能

 DesiredCapabilities capabilities = new DesiredCapabilities();
        capabilities.setCapability("deviceName", "Tab");
        capabilities.setCapability("platformVersion", "8.0.0");
        capabilities.setCapability("platformName", "ANDROID");
        capabilities.setCapability("udid", "5200472dec01a4a9");
        capabilities.setCapability("noReset", "true");

        capabilities.setCapability("newCommandTimeout", 3000);
        capabilities.setCapability("noSign", "true");
        URL mobileURL = new URL("http://0.0.0.0:5050/wd/hub");
        mobileParent = new AndroidDriver(mobileURL, capabilities);

device2-的移动功能

 capabilities.setCapability("deviceName", "Tab");
        capabilities.setCapability("platformVersion", "8.0.0");
        capabilities.setCapability("platformName", "ANDROID");
        capabilities.setCapability("udid", "52002dd24392b5a1");

        mobileDriver = new AndroidDriver(mobileURL, capabilities);

非常感谢！

查看您提供的详细信息，应该没有任何错误。它应该工作正常。

当Appium无法找出为运行提供的功能列表时，通常会发生未知错误。我建议仔细检查appPackage和appActivity详细信息是否正确。

此外，请尝试在一台设备上运行测试并查看任何错误。查看测试运行的一致性。如果不是错误，则可以再添加一台设备并查看其运行方式。

在功能下方添加，

"automationName": "UiAutomator2"

如果在本地计算机上运行测试，请使用http://127.0.0.1:<Port>/wd/hub代替0.0.0.0

如果您要远程运行测试，请确保在上面进行操作，将本地IP 127.0.0.0替换为运行Appium服务器的计算机IP。

由于您仅在运行Android设备，因此希望按照Android测试设置安装必备软件。

对于Mac设备设置，请按照此处的步骤-https://www.swtestacademy.com/how-to-install-appium-on-mac/

您可以在此处添加完整的Appium日志吗...
