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

[PindaPixel]

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" />

     <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
