Unable to run Xcode unit tests from the command line due to otest error
提问by Paul Hansen
I'm trying to run unit tests from the command line but they fail while they run perfectly fine in Xcode 4.6. I can't figure out what's the cause of failure:
我正在尝试从命令行运行单元测试，但它们在 Xcode 4.6 中完美运行时失败了。我无法弄清楚失败的原因是什么：
Here's the command I'm using:
这是我正在使用的命令：
xcodebuild -sdk iphonesimulator -project myproject.xcodeproj
-scheme 'MyProjectApplicationTests'
-configuration Debug clean build
RUN_UNIT_TEST_WITH_IOS_SIM=YES TEST_AFTER_BUILD=YES TEST_HOST=''
I have no usage of NSURL or to 'initFileURLWithPath' in my tests. Here's the error:
我在测试中没有使用 NSURL 或 'initFileURLWithPath'。这是错误：

If there is a way to even print out the callstack (in English), I could maybe figure out where the error is from.
如果有办法甚至打印出调用堆栈（英文），我也许可以找出错误的来源。

The issue is that xcodebuild does not natively support application tests in the simulator. To run applications tests in the simulator from the command line you need an open source utility ios-sim and a tweek to your tests target run script.
问题是 xcodebuild 本身不支持模拟器中的应用程序测试。要从命令行在模拟器中运行应用程序测试，您需要一个开源实用程序 ios-sim 和一个 tweek 到您的测试目标运行脚本。
1)Install ios-sim https://github.com/phonegap/ios-sim
1）安装ios-sim https://github.com/phonegap/ios-sim
$ curl -L https://github.com/phonegap/ios-sim/zipball/1.9.0 -o ios-sim-1.9.0.zip
$ unzip ios-sim-1.9.0.zip
$ cd phonegap-ios-sim-538ef1a/
$ sudo rake install prefix=/usr/local/
2)Edit your tests target run script. This script is from Atlassian's fabulous documentation. I love Atlassian makers of JIRA, Stash, Confluence, and my new best friend SourceTree. Full disclosure they acquired SourceTree and it's developer then released it for FREE.

Application Test vs Logic Tests
The unit test target that is created for new projects is an Application Unit Test. It injects your test code into the app by setting BUNDLE_LOADER and TEST_HOST in the build settings.
The test targets you create from the New Target menu are logic tests. Logic test are stand alone independent from your application.
应用程序测试与逻辑测试
为新项目创建的单元测试目标是应用程序单元测试。它通过在构建设置中设置 BUNDLE_LOADER 和 TEST_HOST 将您的测试代码注入应用程序。您从“新建目标”菜单创建的测试目标是逻辑测试。逻辑测试独立于您的应用程序。
This is my Bundle Loader and Test Host Values.
这是我的捆绑加载器和测试主机值。
Bundle Loader: $(BUILT_PRODUCTS_DIR)/DC Wire Sizer.app/DC Wire Sizer
Test Host: $(BUNDLE_LOADER)
Potential issue:if you have multiple versions of Xcode installed. Then you need to check your xcode-select setting:
潜在问题：如果您安装了多个版本的 Xcode。然后你需要检查你的 xcode-select 设置：
gdunham: ~$ xcode-select -print-path
/Applications/Xcode.app/Contents/Developer
