自 xCode 13 和 iOS 15 以来，Appium（和桌面）无法启动 wda 会话

Posted 2023-03-22

【中文标题】自 xCode 13 和 iOS 15 以来，Appium（和桌面）无法启动 wda 会话

【英文标题】：Appium (and desktop) unable to launch wda session since xCode13 and iOS15

【发布时间】：2021-11-17 18:22:46

【问题描述】：

自从我的 xCode （自动...）更新到 13 并且我的所有模拟器从 ios 14.5 移动到 15。使用相同的设置/命令后，我无法从桌面应用程序和节点启动 WDA （硒服务器网格/节点设置）

所有模拟器都存在此问题。 我仍然可以使用真实设备..

（错误中的实际端口可能有所不同，第一个来自实际的自动化失败，第二个和第三个来自桌面应用程序 - 它仍然失败并出现相同的错误。根本问题仍然相同两者都有）

我得到的错误日志： 简而言之：

【参考方案1】：

为了解决这个问题， 我们需要在电脑上更新我们的appkum（应该是1.22.0或以上）

查看您的版本：

appium -v

安装/更新您的 appium：

npm install -g appium

这修复了模拟器部分。要修复 appium 桌面，您还必须更新桌面应用程序，但现在它已作为 2 个单独的应用程序移动。

一个用于服务器 https://github.com/appium/appium-desktop/releases/

还有一个给检查员https://github.com/appium/appium-inspector/releases

【参考方案2】：

我在旧的 appium（服务器和检查器结合在一起）和新版本的 appium 中遇到了类似的问题，它们被分开了。

我通过添加服务器功能解决了这个问题：

serverCapabilities.setCapability("wdaStartupRetries", "4");
serverCapabilities.setCapability("iosInstallPause","8000" );
serverCapabilities.setCapability("wdaStartupRetryInterval", "20000");

之后，wda会话就稳定了

【讨论】：

这个答案也解决了我的问题。谢谢
