Question

我目前正在使用xunit对项目进行单元测试。但是，当我激活“收集覆盖率”选项时，它表明我正在测试其他模块。

实际上，我正在运行此命令。

dotnet test mymodule.Tests /p:CollectCoverage=true /p:CoverletOutputFormat=opencover

项目文件就是这样。

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>netcoreapp2.1</TargetFramework>

    <IsPackable>false</IsPackable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="coverlet.msbuild" Version="2.5.0">
      <IncludeAssets>runtime; build; native; contentfiles; analyzers</IncludeAssets>
      <PrivateAssets>all</PrivateAssets>
    </PackageReference>
    <PackageReference Include="Microsoft.NET.Test.Sdk" Version="15.8.0" />
    <PackageReference Include="xunit" Version="2.3.1" />
    <PackageReference Include="xunit.runner.visualstudio" Version="2.3.1" />
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\mymodule\mymodule.csproj" />
  </ItemGroup>

</Project>

这是输出。

我的问题是如何仅对mymodule进行测试？

谢谢。

Answer 1

好吧，我认为问题出在coverlet.msbuild上，我试图将版本降级到1.0.0，并且一切正常。

Answer 2

您实际上可以使用标志来指定程序集

-p:Include="[mymodule]*"

此标志指定您只希望覆盖指定的程序集。因此，您最终的cmd将显示为：

dotnet test mymodule.Tests /p:CollectCoverage=true /p:CoverletOutputFormat=opencover /p:Include="[mymodule]*"

指定到特定模块以使用xunit进行测试
