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" />
 	 <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
