从Xcode运行UIAutomation脚本

概述有没有人成功在Xcode中建立自动化UIAutomation测试？ 我试图在我的Xcode项目中设置一个目标，它应该运行我准备的所有UIAutomation脚本。目前，此目标的唯一构建阶段是此运行脚本块： TEMPLATE="/Applications/Xcode.app/Contents/Applications/Instruments.app/Contents/PlugIns/Automati 有没有人成功在Xcode中建立自动化UIautomation测试？

我试图在我的Xcode项目中设置一个目标，它应该运行我准备的所有UIautomation脚本。目前，此目标的唯一构建阶段是此运行脚本块：

TEMPLATE="/Applications/Xcode.app/Contents/Applications/Instruments.app/Contents/PlugIns/automationInstrument.bundle/Contents/Resources/automation.tracetemplate"MY_APP="/Users/Me/library/Application Support/iPhone Simulator/6.0/Applications/564ED15A-A435-422B-82C4-5AE7DBBC27DD/MyApp.app"RESulTS="/Users/Me/Projects/MyApp/Tests/UI/Traces/automation.trace"SCRIPT="/Users/Me/Projects/MyApp/Tests/UI/SomeTest.Js"instruments -t $TEMPLATE $MY_APP -e UIASCRIPT $SCRIPT -e UIARESulTSPATH $RESulTS

当我建立这个目标后，几秒钟后会成功，但脚本实际上没有运行。在构建日志中，我收到以下错误：

instruments[7222:707] Failed to load Mobile Device Locator plugininstruments[7222:707] Failed to load Simulator Local Device Locator plugininstruments[7222:707] automation Instrument ran into an exception while trying to run the script.  UIATargetHasGoneAWolException+0000 Fail: An error occurred while trying to run the script.Instruments Trace Complete (Duration : 1.077379s; Output : /Users/Me/Projects/MyApp/Tests/UI/Traces/automation.trace)

我很确定，我的JavaScript和我的运行脚本都是正确的，因为如果我在bash中运行完全相同的仪器命令，它的工作原理如预期。
这可能是Xcode中的错误吗？

解决方法 我终于找到了解决这个问题的办法。似乎Xcode正在运行有限权限的运行脚本。我不完全确定，什么导致仪器命令失败，但使用su更改为您的用户将修复它。

su $USER -l -c <instruments command>

显然，这将要求您输入密码，但是在作为脚本运行时不能输入密码。我没有找到一种方法来指定su的密码，但是如果以root用户身份运行，则不必指定一个密码。幸运的是sudo可以通过管道接受密码：

echo <password> | sudo -S su $USER -l -c <instruments command>

如果您不想对密码进行硬编码(总是一个坏主意)，您可以使用一些AppleScript来询问密码。

我在下面发布了结果脚本。将其复制到项目中的* .sh文件，并从运行脚本运行该脚本。

#!/bin/bash# This script should run all (currently only one) tests,independently from# where it is called from (terminal,or Xcode Run Script).# REQUIREMENTS: This script has to be located in the same folder as all the# UIautomation tests.
