间歇性发生appium未知服务器端错误

Question

我似乎时断时续地遇到这个问题。如果我拔下插头并重新插入设备并重新执行测试，则没有错误，但这只是暂时的修复，直到它再次出现。我有2个appium server实例，用于2台设备-

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

52002dd24392b5a1        device
5200472dec01a4a9        device

设备所需的功能1-

 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("appPackage", "com.xyz.xyz");
        capabilities.setCapability("appActivity", "host.exp.exponent.LauncherActivity");
        capabilities.setCapability("adbExecTimeout", 120000);
        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);

设备的移动功能2-

 capabilities.setCapability("deviceName", "Tab");
        capabilities.setCapability("platformVersion", "8.0.0");
        capabilities.setCapability("platformName", "ANDROID");
        capabilities.setCapability("udid", "52002dd24392b5a1");
        capabilities.setCapability("noReset", "true");
        capabilities.setCapability("appPackage", "com.coachhire.kura");
        capabilities.setCapability("appActivity", "host.exp.exponent.LauncherActivity");
        capabilities.setCapability(AndroidMobileCapabilityType.AUTO_GRANT_PERMISSIONS, true);
        capabilities.setCapability("adbExecTimeout", 120000);
        capabilities.setCapability("newCommandTimeout", 3000);
        capabilities.setCapability("noSign", "true");
        URL mobileURL = new URL("http://0.0.0.0:4723/wd/hub");
        mobileDriver = new AndroidDriver(mobileURL, capabilities);

非常感谢任何帮助！

看看你提供的细节，应该不会有任何错误。它应该可以正常工作。

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

此外，尝试在一台设备上运行测试并查看任何错误。请参阅测试运行的一致性。如果没有错误，您可以再添加一个设备并查看其运行情况。

在以下功能中添加，

"automationName": "UiAutomator2"

如果您在本地计算机上运行测试，请使用<代码>http://127.0.0.1:

如果您正在远程运行测试，请确保在上面，本地IP127.0.0.0替换为运行Appium服务器的机器IP。

由于您只运行Android设备，我希望根据Android测试设置安装必备软件。

对于mac设备设置，请执行以下步骤-https://www.swtestacademy.com/how-to-install-appium-on-mac/

尝试以下步骤，

检查您可以通过运行下面的命令手动安装应用程序。

 adb -P <port> -s <device id > shell pm install -t -g <apk path>

如果这可以工作，这表明设备没有问题。否则，您应该重置设备并重新测试它。

检查Appium服务器是否运行没有问题。并访问此链接，看到您在appium服务器控制台上获得200个响应。

http://<appium server ip>:4723/wd/hub/sessions

您应该知道，有时节点。js无法与127.0.0.1:4723交谈，因此请使用0.0.0.0:4723，反之亦然。记住在代码（DesiredCapabilities）和应用程序设置中都要更改此设置。

Try“udid”参数是所需功能所必需的-

示例，caps.set能力（"udid"，"ce0217124184c72505"）；//来自"adb设备"命令的DeviceId
