Specflow + MSTest：測試失敗，錯誤爲「無法加載文件或程序集'MyPlugin.SpecFlowPlugin'或它的一個依賴項'

我正在使用MSTest和命令行運行specflow測試。項目建立沒有錯誤，但測試失敗，出現錯誤：Specflow + MSTest：測試失敗，錯誤爲「無法加載文件或程序集'MyPlugin.SpecFlowPlugin'或它的一個依賴項'

Class Initialization method MyProject.SpecFiles.MyFeature.FeatureSetup threw exception. TechTalk.SpecFlow.SpecFlowException: TechTalk.SpecFlow.SpecFlowException: Unable to load plugin: MyPlugin. Please check http://go.specflow.org/doc-plugins for details. ---> System.IO.FileNotFoundException: Could not load file or assembly 'MyPlugin.SpecFlowPlugin' or one of its dependencies. The system cannot find the file specified.WRN: Assembly binding logging is turned OFF. 
To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1. 
Note: There is some performance penalty associated with assembly bind failure logging. 
To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fusion!EnableLog].

任何人可以幫助我嗎？

問題可能是您的插件dll（或其依賴關係之一）在specflow期望從其加載的位置找不到。

您可以指定位置找到應用程序的.config插件爲explained in the documentation：

The following example is used to load a plugin assembly called "MyNewPlugin.SpecFlowPlugin.dll" that is located in a folder called "Binaries" that is at the same level of the current project.

<specFlow> 
    <plugins> 
     <add name="MyNewPlugin" path="..\Binaries" /> 
    </plugins> 
</specFlow>

檢查構建服務器的輸出上看到正在創建的插件DLL，並且或者適當地調整版本或配置

以下行存在於App.config中' PavelAnih

看起來像你試圖在你的項目中加載程序集。爲了加載程序集，您必須在app.config中添加以下代碼。

<stepAssemblies> 
    <stepAssembly assembly="{name-of-assembly-containing-bindgins}" /> 
</stepAssemblies>

在App.config中有步驟組件。 – PavelAnih

問題已解決。我已添加.testsettings文件與選中的部署複選框。部署項目 - 具有所有必需dll的bin文件夾。
