Xcode Server CI Bot 测试会话已退出（-1）

Question

尝试在 XcodeServer 上针对模拟器设备运行测试时出现错误。测试有时会通过一个设备而对另一个设备失败，但失败的设备并不总是同一个设备。这可以在单个会话中发生。

日志文件错误如下：

任何想法都会很有帮助。

Answer 1

尝试在服务器上启动此命令：

sudo /usr/sbin/DevToolsSecurity --enable

Answer 2

模拟器需要用户 GUI 上下文才能运行。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 开发人员有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，并让该用户持续登录。我认为 Apple 会在安装过程中解决这个问题。
