Unable to detect unit tests in project with multiple package.json files

Bắt đầu bằng cách tái tạo dự án ASP.NET Core with Angular được mô tả trong issue, bao gồm các tệp package.json ở root và ClientApp, cùng cấu hình JavaScriptTestRoot. Kiểm tra cách tích hợp Microsoft.JavaScript.UnitTest phát hiện các test cho dự án và xác minh kết quả trong Test Explorer. Hoàn thành khi các unit test Karma/Jasmine được phát hiện với cả hai tệp package.json đều hiện diện.

Expected Behavior

Unit tests are found when multiple package.json files exist in the project.

Actual Behavior

• NTVS Version: 1.5.10610.1
• Visual Studio Version: 2022 17.7.6
• Node.js Version: 20.8.1

Steps to Reproduce

1. Create a project using the ASP.NET Core with Angular template
2. Add a package.json at the root level of the project, now the folder structure should look as follows (excerpt):

   MyProject/
   ├─ ClientApp/
   │  ├─ package.json
   ├─ Controllers/
   ├─ Pages/
   ├─ wwwroot/
   ├─ package.json
   ├─ Program.cs
   

3. Edit the project configuration for unit testing with Karma/Jasmine:

<Project Sdk="Microsoft.NET.Sdk.Web">
    <PropertyGroup>
  	  <TargetFramework>net7.0</TargetFramework>
  	  <Nullable>enable</Nullable>
  	  <IsPackable>false</IsPackable>
  	  <SpaRoot>ClientApp\</SpaRoot>
  	  <SpaProxyServerUrl>https://localhost:44445</SpaProxyServerUrl>
  	  <SpaProxyLaunchCommand>npm start</SpaProxyLaunchCommand>
  	  <ImplicitUsings>enable</ImplicitUsings>

  	  <!-- Unit tests -->
  	  <JavaScriptTestRoot>ClientApp\</JavaScriptTestRoot>
  	  <JavaScriptTestFramework>Jasmine</JavaScriptTestFramework>
  	  <GenerateProgramFile>false</GenerateProgramFile>
    </PropertyGroup>

    <ItemGroup>
  	  <PackageReference Include="Microsoft.AspNetCore.SpaProxy" Version="7.0.13" />
  	  <PackageReference Include="Microsoft.JavaScript.UnitTest" Version="1.5.10610.1">
  		  <PrivateAssets>all</PrivateAssets>
  		  <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
  	  </PackageReference>
    </ItemGroup>

    <ItemGroup>
  	  <!-- Don't publish the SPA source files, but do show them in the project files list -->
  	  <Content Remove="$(SpaRoot)**" />
  	  <None Remove="$(SpaRoot)**" />
  	  <None Include="$(SpaRoot)**" Exclude="$(SpaRoot)node_modules\**" />
    </ItemGroup>

    <Target Name="DebugEnsureNodeEnv" BeforeTargets="Build" Condition=" '$(Configuration)' == 'Debug' And !Exists('$(SpaRoot)node_modules') ">
  	  <!-- Ensure Node.js is installed -->
  	  <Exec Command="node --version" ContinueOnError="true">
  		  <Output TaskParameter="ExitCode" PropertyName="ErrorCode" />
  	  </Exec>
  	  <Error Condition="'$(ErrorCode)' != '0'" Text="Node.js is required to build and run this project. To continue, please install Node.js from https://nodejs.org/, and then restart your command prompt or IDE." />
  	  <Message Importance="high" Text="Restoring dependencies using 'npm'. This may take several minutes..." />
  	  <Exec WorkingDirectory="$(SpaRoot)" Command="npm install" />
    </Target>

    <Target Name="PublishRunWebpack" AfterTargets="ComputeFilesToPublish">
  	  <!-- As part of publishing, ensure the JS resources are freshly built in production mode -->
  	  <Exec WorkingDirectory="$(SpaRoot)" Command="npm install" />
  	  <Exec WorkingDirectory="$(SpaRoot)" Command="npm run build -- --configuration production" />

  	  <!-- Include the newly-built files in the publish output -->
  	  <ItemGroup>
  		  <DistFiles Include="$(SpaRoot)dist\**; $(SpaRoot)dist-server\**" />
  		  <ResolvedFileToPublish Include="@(DistFiles->'%(FullPath)')" Exclude="@(ResolvedFileToPublish)">
  			  <RelativePath>wwwroot\%(RecursiveDir)%(FileName)%(Extension)</RelativePath>
  			  <CopyToPublishDirectory>PreserveNewest</CopyToPublishDirectory>
  			  <ExcludeFromSingleFile>true</ExcludeFromSingleFile>
  		  </ResolvedFileToPublish>
  	  </ItemGroup>
    </Target>
</Project>

4. Reload the project
5. Notice the Test Explorer is unable to find any tests
