無法從命令行運行Xcode單元測試由於錯誤

Question

我試圖從命令行運行單元測試，但它們在Xcode 4.6中運行完美時失敗。在我的測試

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='' 

我沒有NSURL的使用情況或「initFileURLWithPath」：我無法弄清楚什麼是失敗的原因：

下面是我使用的命令。這裏的錯誤：

/Applications/Xcode.app/Contents/Developer/Tools/RunPlatformUnitTests.include:412: note: Started tests for architectures 'i386'

如果有辦法，甚至打印出調用堆棧（英文），我也許可以找出錯誤所在距離。

問題是xcodebuild本身不支持模擬器中的應用程序測試。要從命令行在模擬器中運行應用程序測試，需要開放源代碼實用程序ios-sim和測試目標運行腳本的tweek。

1）安裝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）編輯您的測試目標上運行的腳本。這個腳本來自Atlassian的神話般的文檔。我喜歡JIRA，Stash，Confluence以及我最新的好朋友SourceTree的Atlassian製造商。充分披露他們收購SourceTree，然後開發者免費發佈。

替換現有的：

# Run the unit tests in this test bundle. 
"${SYSTEM_DEVELOPER_DIR}/Tools/RunUnitTests" 

有了這個（來源：https://confluence.atlassian.com/display/BAMBOO/Xcode）

if [ "$RUN_UNIT_TEST_WITH_IOS_SIM" = "YES" ]; then 
    test_bundle_path="$BUILT_PRODUCTS_DIR/$PRODUCT_NAME.$WRAPPER_EXTENSION" 
    ios-sim launch "$(dirname "$TEST_HOST")" --setenv DYLD_INSERT_LIBRARIES=/../../Library/PrivateFrameworks/IDEBundleInjection.framework/IDEBundleInjection --setenv XCInjectBundle="$test_bundle_path" --setenv XCInjectBundleInto="$TEST_HOST" --args -SenTest All "$test_bundle_path" 
    echo "Finished running tests with ios-sim" 
else 
    "${SYSTEM_DEVELOPER_DIR}/Tools/RunUnitTests" 
fi 

3）運行測試

xcodebuild \ 
    -sdk iphonesimulator6.1 \ 
    -project DC\ Wire\ Sizer.xcodeproj \ 
    -target DC\ Wire\ Sizer\ Tests \ 
    -configuration Debug \ 
    RUN_UNIT_TEST_WITH_IOS_SIM=YES 

...

有用的命令：

xcodebuild聯編-showsdks

$ xcodebuild -showsdks 
OS X SDKs: 
    Mac OS X 10.7     -sdk macosx10.7 
    OS X 10.8      -sdk macosx10.8 

iOS SDKs: 
    iOS 6.1       -sdk iphoneos6.1 

iOS Simulator SDKs: 
    Simulator - iOS 4.3    -sdk iphonesimulator4.3 
    Simulator - iOS 5.0    -sdk iphonesimulator5.0

    Simulator - iOS 6.0    -sdk iphonesimulator6.0 
    Simulator - iOS 6.1    -sdk iphonesimulator6.1 

xcodebuild聯編-list -project

$ xcodebuild -list -project DC\ Wire\ Sizer.xcodeproj 
Information about project "DC Wire Sizer": 
    Targets:

     DC Wire Sizer Tests 
     In Work Unit Test 

    Build Configurations: 
     Debug 
     Release_AppStore 
     Release_TestFlight 

    If no build configuration is specified and -scheme is not passed then "Release_AppStore" is used. 

    Schemes: 
     DC Wire Sizer 
     DC Wire Sizer - App Store 
     InWorkUnitTest 

應用試驗VS邏輯測試
爲新項目創建的單元測試目標是應用程序單元測試。它通過在構建設置中設置BUNDLE_LOADER和TEST_HOST將您的測試代碼注入到應用程序中。 您從New Target菜單創建的測試目標是邏輯測試。邏輯測試獨立於您的應用程序。

這是我的Bundle加載器和測試主機值。

Bundle Loader: $(BUILT_PRODUCTS_DIR)/DC Wire Sizer.app/DC Wire Sizer 
Test Host:  $(BUNDLE_LOADER) 

潛在的問題：如果安裝的Xcode的多個版本。然後你需要檢查你的xcode選擇設置：

gdunham: ~$ xcode-select -print-path 
/Applications/Xcode.app/Contents/Developer
