unit-testing - 由于找不到 "TechTalk.SpecFlow"文件，SpecFlow 单元测试失败

Question

我有一个设置为使用 SpecFlow 1.8.1 和 mstest 的 VS2010 单元测试项目。为了让 SpecFlow 单元测试正常工作，我做了以下工作:-

我在我的项目中添加了对以下文件的引用:-

Microsoft.VisualStudio.QualityTools.UnitTestFramework.dllTechTalk.SpecFlow.dll

Note that the TechTalk.SpecFlow.dll has been added into my project and the reference points to that file.

I've set the "Copy Local" property of the TechTalk.SpecFlow.dll reference to True.

I've also added an App.Config that specifies "MsTest.2010" as the provider, and regenerated all code-behinds for the SpecFlow features.

Everything works in my VS2010, the tests run successfully in both the SpecFlow testrunner and the mstest test runner. BUT when I try to run the mstests in TFS 2008 (using a .vsmdi test list file), it failed with the following exception:-

Class Initialization method MyNamespace.MyTestFeature.FeatureSetup threw exception.
System.Configuration.ConfigurationErrorsException:
System.Configuration.ConfigurationErrorsException: An error occurred creating the
configuration section handler for specFlow: Could not load file or assembly
'TechTalk.SpecFlow' or one of its dependencies. The system cannot find the file
specified. (D:\Projects\TestProject\TestResults\administrator_MYPC 2012-06-27
18_30_05_Any CPU_Debug\Out\TestProject.DLL.config line 4) --->
System.IO.FileNotFoundException: Could not load file or assembly 'TechTalk.SpecFlow'
or one of its dependencies. The system cannot find the file specified.

请注意，TFS 很好地构建了项目，并且它在同一项目(正常的 mstests，而不是 SpecFlow)中运行其他单元测试没有问题。它仅在 SpecFlow 测试运行中失败。

那么我做错了什么？

编辑:我的 App.Config 文件的内容如下所示:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <section
       name="specFlow"
       type="TechTalk.SpecFlow.Configuration.ConfigurationSectionHandler, TechTalk.SpecFlow"/>
  </configSections>
  <specFlow>
    <unitTestProvider name="MsTest.2010" />

    <runtime detectAmbiguousMatches="true"
         stopAtFirstError="false"
         missingOrPendingStepsOutcome="Inconclusive" />

    <trace traceSuccessfulSteps="true"
           traceTimings="false"
           minTracedDuration="0:0:0.1" />
  </specFlow>
</configuration>

按照 this site 上的说明进行操作和 this site :

命令 Tools > Library Package Manager > Package Manager Console允许您输入 PM> Install-Package SpecFlow
当提示返回“安装成功”时，SpecFlow 程序集现在出现在您项目的引用中。现在 MSTest 项目编译成功(至少对我而言)。
