尝试在XcodeServer上针对模拟器设备运行测试时出错。测试有时会传递给一个设备而另一个设备会失败，但是失败的设备并不总是相同的。这可能发生在一个会话中。
日志文件错误如下：

任何想法都会非常有用。
答案 0 :(得分：2)
模拟器需要运行用户GUI上下文。如果服务器是从/ Library / LaunchDaemons启动的，那么它在系统（根）上下文中运行，并且没有GUI上下文。如果使用Atlassian Bamboo as well as Jenkins for CI，这是一个问题。 Facebook开发者有also encountered this problem with xctool。
您可能需要从用户上下文启动XcodeServer，即在〜/ Library / LaunchAgents中创建一个plist文件，并让该用户连续登录。我认为Apple会在安装过程中解决该问题。
