What's the Default .runsettings file in VS2026->tools->option->Test Coverage #248

Why VS2026 Output window shows looks very different as github.said :
https://github.com/microsoft/codecoverage/blob/main/docs/configuration.md#runsettings-file
<RunSettings> <BoostTestInternalSettings xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <VSProcessId>28568</VSProcessId> </BoostTestInternalSettings> <RunConfiguration> <EnvironmentVariables> //... </RunConfiguration> <GoogleTestAdapterSettings xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <SolutionSettings> <Settings /> </SolutionSettings> <ProjectSettings /> </GoogleTestAdapterSettings> </RunSettings>.

Another question: according the url:
https://learn.microsoft.com/en-us/dotnet/core/testing/test-platforms-overview
looks has 2 test platform, which platform running when run analyzer code coverage in VS2026 by default, how can I see it? what's the default configuration of it when running?

means test project must using Microsoft.Testing.Platform ,otherwise will running by VSTest right? (like following codes in .csproj)

  <ItemGroup>
	  <PackageReference Include="coverlet.collector" Version="6.0.4" />
	  <PackageReference Include="Microsoft.NET.Test.Sdk" Version="17.14.1" />
	  <PackageReference Include="MockQueryable.Moq" Version="10.0.8" />
	  <PackageReference Include="Moq" Version="4.20.72" />
	  <PackageReference Include="xunit.runner.visualstudio" Version="3.1.4" />
	  <PackageReference Include="xunit.v3" Version="3.2.2" />
	  <PackageReference Include="Microsoft.AspNetCore.Diagnostics.Abstractions" Version="2.2.0" />
  </ItemGroup>

what if I want to test upper test project when following document：https://learn.microsoft.com/en-us/dotnet/core/tools/dotnet-test-vstest
dotnet test xxx.csproj --collect "Code Coverage"
failed: Unknown option '--collect'

thanks

global.json is used to determine the test runner (MTP or vstest). https://learn.microsoft.com/en-us/dotnet/core/testing/microsoft-testing-platform-migration-from-v1-to-v2#compatibility-with-vstest-based-dotnet-test

That means without any MTP introduce, analyzer code coverage in VS2026 will run an vstest right?

In this document ,I think dotnet test also run with vstest by default without migration to MTP :https://learn.microsoft.com/en-us/dotnet/core/testing/migrating-vstest-microsoft-testing-platform. right?
If yes,the question is that I run with dotnet test cmd:
dotnet test xxx.csproj -s "coverage.runsettings"
and VS2026 analyzer code coverage run same test project with same coverage.runsettings, why coverage line report different?

thanks

the following img configure same .runsetting file.
vstest.console.exe

VS2026 analyzer code coverage

dotnet test

can pls answer the question: VS2026 analyzer code coverage running by VSTest if MTP not introduce right? thanks
