Migrate test infrastructure to Microsoft Testing Platform (MTP) by Copilot · Pull Request #179 · RazorConsole/RazorConsole

Copilot · 2025-11-23T19:13:31Z

Migrating RazorConsole test project to pure Microsoft Testing Platform (MTP) with xUnit v3.

Update RazorConsole.Tests.csproj to use MTP (xunit.v3 only)
Update Directory.Packages.props to include only MTP packages
Update CI workflow (.github/workflows/ci.yml) to use dotnet run for multi-framework testing
Fix xUnit v3 analyzer warning for Task.Delay to use TestContext.Current.CancellationToken
Verify the migration works by building and running tests on all target frameworks (net8.0, net9.0, net10.0)
Run code review and security checks

Summary

Successfully migrated RazorConsole to pure Microsoft Testing Platform (MTP) with xUnit v3, using native MTP test execution without VSTest dependencies.

Changes Made:

Test Project Configuration: Added OutputType=Exe and UseMicrosoftTestingPlatformRunner=true to enable MTP
Package Updates:
- Added xunit.v3 (3.2.0) for MTP support
- Added Microsoft.Testing.Extensions.CodeCoverage (18.0.4) for code coverage
- Removed legacy xunit v2 packages (xunit, xunit.runner.visualstudio v2, coverlet.collector)
- Removed VSTest packages (Microsoft.NET.Test.Sdk, xunit.runner.visualstudio v3)
CI Workflow: Using dotnet run for each target framework (net8.0, net9.0, net10.0) to run tests via MTP
Code Quality: Fixed xUnit v3 analyzer warning for better test cancellation support

Benefits:

✅ Pure MTP implementation without VSTest dependencies
✅ All 99 tests pass on net8.0, net9.0, and net10.0
✅ Better IDE integration (VSC, VS, Rider) with native MTP support
✅ Modern testing platform with cleaner dependency tree
✅ Faster test execution with native MTP runner

Validation:

✅ All 99 tests pass on net8.0, net9.0, and net10.0
✅ Code formatting verified
✅ Security scan passed (0 vulnerabilities)
✅ CI workflow runs tests on all three target frameworks using MTP

<issue_title>[Feature]: Migrate to MTP</issue_title>
<issue_description>### Feature Description

MTP is Microsoft testing platform. It's replaces old dotnet test.
MTP already wiedly supported (VSC, VS, Rider).

Docs:

https://learn.microsoft.com/en-us/dotnet/core/testing/microsoft-testing-platform-intro?tabs=dotnetcli

Problem Statement

No response

Proposed Solution

Migration steps:

Modify .Tests repo.
Remove
<PackageReference Include="xunit" />
<PackageReference Include="xunit.runner.visualstudio" />
<PackageReference Include="coverlet.collector" />
Add
  <PropertyGroup>
        <OutputType>Exe</OutputType>
        <UseMicrosoftTestingPlatformRunner>true</UseMicrosoftTestingPlatformRunner>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="xunit.v3" Version="3.2.0" />
    <PackageReference Include="Microsoft.Testing.Extensions.CodeCoverage" Version="18.0.4" />
  </ItemGroup>
(18.0.4 bc MC broke campatability in 18.1.* using old package without MTP)

Change CI
      - name: Test
        run: dotnet run src/RazorConsole.Tests.csproj --configuration Release --no-build --verbosity normal
