selenium-webdriver - 自 xCode13 和 iOS15 以来，Appium（和桌面）无法启动 wda 会话

问题描述

由于我的 xCode（自动...）更新到 13，并且我的所有模拟器都从 iOS 14.5 移到了 15。使用相同的设置/命令，我无法从桌面应用程序和节点（硒服务器）启动 WDA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不同，第一个来自失败的实际自动化，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。两者的根本问题仍然相同）

我得到的错误日志：简而言之：

解决方案

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，它们分别被取出。

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会话稳定了
