如何让 Resharper 将 Specflow 绑定、Step Def 等注释视为隐式使用

Question

我正在使用带有 Specflow 的 Reshaper，ResharperCode 检查将步骤定义、绑定和挂钩标记为从未使用过。

我尝试使用here的答案

但未能成功获取正确拾取的外部注释。这是我在外部注释文件中尝试的内容：-

<assembly name="TechTalk.SpecFlow.dll">
  <member name="T:TechTalk.SpecFlow.BindingAttribute">
    <attribute ctor="M:JetBrains.Annotations.MeansImplicitUseAttribute.#ctor" />
  </member>
  <member name="T:TechTalk.SpecFlow.GivenAttribute">
    <attribute ctor="M:JetBrains.Annotations.MeansImplicitUseAttribute.#ctor" />
  </member>
    <member name="T:TechTalk.SpecFlow.WhenAttribute">
    <attribute ctor="M:JetBrains.Annotations.MeansImplicitUseAttribute.#ctor" />
  </member>
  <member name="T:TechTalk.SpecFlow.ThenAttribute">
    <attribute ctor="M:JetBrains.Annotations.MeansImplicitUseAttribute.#ctor" />
  </member>
</assembly>

我尝试将其保存在 C:\Program Files (x86)\JetBrains\ReSharper\v8.2\Bin 和 C:\Program Files (x86)\JetBrains\ReSharper\v8.2\Bin\ExternalAnnotations 中（不太清楚应该去哪里，因为默认安装中不存在 ExternalAnnotations 文件夹）

但是当我关闭并重新打开 VS 时，Inspection 仍然会选择未使用的绑定和步骤定义：-

Solution qdf.AcceptanceTests.sln
Project Alpari.QualityAssurance.SpecFlowExtensions
  Alpari.QualityAssurance.SpecFlowExtensions\Steps\CrossStepDefinitionFileTwo.cs:7 Class 'CrossStepDefinitionFileTwo' is never used
  Alpari.QualityAssurance.SpecFlowExtensions\Steps\CrossStepDefinitionFileTwo.cs:10 Method 'GivenICreateAnInstanceOfStepDefinitionOneFromStepDefinitionTwo' is never used
  Alpari.QualityAssurance.SpecFlowExtensions\Steps\CrossStepDefinitionFileTwo.cs:42 Method 'GivenICallAMethodInStepDefinitionTwoThatCallsTheSameMethodInStepDefinitionFileOne' is never used

谁能告诉我我在配置这个时做错了什么？

EDIT 完成了在 Alexander 的帖子之后运行良好的 xml：-

Answer 1

1. 将您的 TechTalk.SpecFlow.xml 放入 C:\Program Files (x86)\JetBrains\ReSharper\v8.2\Bin\ExternalAnnotations\;

2. 从您提到的 xml 中的 <assembly name="TechTalk.SpecFlow.dll"> 中删除“.dll”扩展名以获得 <assembly name="TechTalk.SpecFlow">；

3. 重新打开 Visual Studio；

4. 为解决方案清理 ReSharper 缓存；

Answer 2

看起来不错，但是从 ReSharper 8.2 开始，外部注释被部署为 ReSharper 的扩展（在扩展管理器中），因此它们不再位于 Program Files 下。

你可以做的，只是为了测试它是否有效，将文件命名为TechTalk.SpecFlow.ExternalAnnotations.xml，并将它放在你的 DLL 旁边（我假设你正在使用 SpecFlow Nuget 包，所以暂时把它放在那里，在库）。您需要重新加载您的解决方案。然后，您应该能够查看是否应用了这些属性。您还可以使用 QuickDoc 功能（通过在属性上按 Ctrl-Q 或 Ctrl-Shift-F1）来确定是否应用了该属性，例如：

如果这确实有效，那么您可以自己将注释分发为ReSharper extension！
