间歇性出现 appium 未知服务器端错误

Question

我似乎间歇性地遇到这个问题。如果我要拔下并重新插入设备并重新执行测试，没有错误，但这只是临时修复，直到它再次出现。我有 2 个用于 2 个设备的 appium 服务器实例-

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

设备 1 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("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 2 的移动功能-

 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！

Answer 1

看你提供的细节，应该没有错误。它应该工作正常。

当 Appium 无法找出为运行提供的功能列表时，通常会出现未知错误。我建议仔细检查 appPackage 和 appActivity 细节是否正确。

此外，请尝试运行在一台设备上进行测试并查看是否有任何错误。查看测试的一致性运行。如果没有错误，您可以再添加一台设备并查看它的运行情况。

在下面添加功能，

"automationName": "UiAutomator2"

如果您运行正在本地machine 上测试，请使用http://127.0.0.1:<Port>/wd/hub代替0.0.0.0

如果您正在运行ning 进行远程测试，请确保在上面将本地 IP 127.0.0.0 替换为 Appium 服务器运行ning 的 machine IP。

由于您仅运行宁 Android 设备，我希望根据 Android 测试设置安装先决条件软件。

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

尝试以下步骤，

检查您是否可以通过以下命令运行ning 手动安装应用程序。

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

如果可以，说明设备没有问题。否则，您应该重置设备并重新测试。

检查 Appium 服务器运行没有问题。并访问此 link 并看到您在 appium 服务器控制台上获得 200 响应。

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

如果您在那里看到错误，则表明 Appium 存在问题。卸载安装稳定版Appium，重新测试

您应该知道，有时 Node.js 无法与 127.0.0.1:4723 通话，因此请使用 0.0.0.0:4723 代替，反之亦然。请记住在代码 (DesiredCapabilities) 和 appium 设置中更改此项。

尝试 "udid" 所需功能需要参数 -

示例，caps.setCapability("udid", "ce0217124184c72505"); //来自"adb devices"命令的DeviceId
