Question

当我遇到困难时，我跟着this tutorial在我的应用上设置了单元测试。

在该教程的第8点，它显示了这个图像，这是我在构建时应该期待的：alt text http://developer.apple.com/library/ios/documentation/Xcode/Conceptual/iphone_development/art/logic_test_failure_text_editor.jpg

然而，这不是我建立时所得到的。我收到此错误消息：Command /bin/sh failed with exit code 1以及单元测试已创建的错误消息。然后，当我扩展第一个错误时，我得到了这个：

PhaseScriptExecution "Run Script" "build/3D Pool.build/Debug-iphonesimulator/LogicTests.build/Script-1A6BA6AE10F28F40008AC2A8.sh"
cd "/Users/james/Desktop/FYP/3D Pool"
setenv ACTION build
setenv ALTERNATE_GROUP staff
...
setenv XCODE_VERSION_MAJOR 0300
setenv XCODE_VERSION_MINOR 0320
setenv YACC /Developer/usr/bin/yacc
/bin/sh -c "\"/Users/james/Desktop/FYP/3D Pool/build/3D Pool.build/Debug-iphonesimulator/LogicTests.build/Script-1A6BA6AE10F28F40008AC2A8.sh\""

Command /bin/sh failed with exit code 1

现在这是非常奇怪的，因为它正在运行测试（并且成功，因为你可以看到我的STFail激发），因为如果我添加一个不同的测试通过我没有错误，所以测试工作正常。但为什么我得到这个额外的构建失败？

也许值得注意的是，当下载应该解决方案的解决方案/模板时，我会得到同样的错误。我猜我在这里设置了一些错误，但我只是正确地遵循了100％的教程！

编辑：根据this blog，this post和其他一些网站，我不是唯一一个遇到此问题的网站。自xCode 3.2发布以来就是这样，假设苹果开发中心文档和教程等也是3.2之前的版本。

然而有些人说这是一个已知问题，而其他人似乎认为这是故意的。我想要扩展控制台和代码消息，我当然不喜欢“Command / bin / sh ...”错误，并且真的认为他们会记录这样的更新。希望无论如何它很快就会被修复。

更新：这是确认自xCode 3.2.1发布以来发生了一些变化。

此图片： alt text http://ing0.co.uk/info/pics/unittest-xcode-3.2.1.png来自我使用3.2.1的测试版本。这个来自旧版本（3.1.4）： alt text http://ing0.co.uk/info/pics/unittest-xcode-3.1.4.png。（两者的项目没有变化）。

Answer 1

双击“目标”/“您的脚本目标名称”下的“运行脚本”，然后键入

# Run the unit tests in this test bundle. 
"${SYSTEM_DEVELOPER_DIR}/Tools/RunUnitTests" 1> /tmp/RunUnitTests.out

基本上你需要追加

1> /tmp/RunUnitTests.out

已经存在的内容

Answer 2

您是否尝试将测试用例的构建配置设置为“Debug”？

我做到了，如http://nothing2fancy.com/2009/08/04/failed-tests-for-architecture-i386-gc-off/所示，它有效

Answer 3

尝试检查此问题SenTestCase in Xcode 3.2 and XCBuildLogCommandInvocationSection Errors

该问题的解决方法对我有用。

Answer 4

菜单：项目 - ＆gt;新建阶段 - ＆gt;新的RunScript构建阶段 - ＆gt;将以下内容粘贴到空文本区域：

"${SYSTEM_DEVELOPER_DIR}/Tools/RunUnitTests" 1> /tmp/RunUnitTests.out

现在尝试构建，你应该在失败的单元测试中得到错误。

Answer 5

我不知道它是否正确，但它对我有用。

在信息测试用例的常规选项卡中，我添加我的主应用程序可执行目标作为直接依赖。

'i386'没有错误（GC OFF）“。

祝你好运。

Answer 6

创建第一个测试用例类时，请确保将Target设置为UnitTest目标，而不是应用程序目标。

如果您在创建课程时忘记执行此操作，则可以在现有课程中“获取信息”，并在那里设置目标....

Answer 7

好的，从来没有玩过XCode中的单元测试（当然我喜欢JUnit在古老的java时代）。所以这只是一个试验：你使用什么编译器，GCC或LLVM？也许GCC是更安全的选择。

启用项目设置中的“仅构建活动体系结构”时，您是否具有相同的行为？这个开关在构建armv6和armv7时会删除重复的错误消息，也许它是相关的。

请查看苹果最新的sample。下载代码时，会有一个自述文件，其中写有：

Running Logic Tests
To run the logic tests:
1. Choose Project > Set Active Target > CalculatorTests.
2. Choose Project > Set Active SDK > Simulator.
3. Choose Build > Build. Xcode runs the test cases implemented in
   the CalculatorTests.m file.
4. Choose Build > Build Results to open the Build Results window, containing
   the tests results. You may have to click the Show Transcript button (the
   third button on the bottom-left corner of the build results list) to view
   the build transcript.

The logic-tests results look similar to this:

Remember that logic tests are executed as part of the build process to provide
you with build errors for failed unit tests. Logic unit-test bundles are not
intented to run in iPhone Simulator or a device.

因此，sentesting工具包有一些变化。我不认为提交错误是值得的。

Answer 9

这是预期的行为。如果其中一个测试失败，构建将失败，如果所有测试都通过，构建将成功。

使用iOS实现单元测试
