  • [x] Update test projects to reference Microsoft.DotNet.XUnitExtensions instead of custom TestUtilities
  • [x] Migrate test code to use arcade attributes (different namespace and API)
  • [x] Add Microsoft.DotNet.XUnitExtensions to Central Package Management
  • [x] Remove custom TestUtilities project
  • [x] Address all code review feedback
  • [x] Fix build scripts to remove deleted TestUtilities references
  • [x] Remove duplicate platform attributes from test methods
  • [x] Fix StyleCop using directive ordering errors (SA1210) - all instances
  • [x] Fix incorrect Theory/Fact attribute mappings
  • [x] Revert hallucinated changes to AI Integration test files
  • [x] Remove incorrect platform attribute from utility class
  • [x] Fix remaining StyleCop using directive ordering issues
  • [x] Restore accidentally removed #pragma warning disable lines
  • [x] Complete migration of all remaining custom test attributes
  • [x] Apply ConditionalClass attribute to MarkItDownReaderTests
  • [x] Simplify ConditionalFact to remove redundant condition parameter
  • [x] Fix SA1649: Rename file to match class name
  • [x] Fix all SA1210 using directive ordering errors
  • [x] Verify all test projects build successfully in Release mode

  • Fixed using directive ordering to satisfy StyleCop SA1210 (alphabetically sorted, no blank line between System and other usings)
  • Fixed incorrect mappings where [ConditionalFact] was converted to [Theory] instead of [Fact] for tests without parameters
  • Removed [CombinatorialData] from tests with no parameters
  • Reverted hallucinated changes to AI Integration test files (kept only using directive fixes)

✅ Build Verification:

  • No SA1210 StyleCop errors remain
  • No SA1649 file naming errors remain
  • No build errors from missing #pragma warning disable directives
  • No build errors from ITestCondition, OSSkipCondition, or OperatingSystems references
  • All custom test utilities have been replaced with arcade equivalents
  • No project references remain to the deleted TestUtilities project
  • Build scripts no longer reference deleted TestUtilities project
  • Using directives properly formatted and alphabetically sorted
  • Only minimal, necessary changes applied to test files
  • All test projects build successfully in Release mode with no warnings or errors

📊 Impact:

  • Files changed: ~110 files
  • Lines deleted: ~710 (removed custom helpers and attributes)
  • Lines added: ~135 (helper class, package references, attribute updates, pragma directives)
  • Net reduction: ~575 lines
  • Projects updated: 11 test projects
  • Zero duplication: Custom utilities removed, using official arcade package

The migration is complete and the repository now uses the standardized Microsoft.DotNet.XUnitExtensions package from dotnet/arcade, eliminating duplication and aligning with other .NET repositories.

Original prompt

This section details on the original issue you should resolve

<issue_title>Custom aspnet xunit extensions should be converged with XUnitExtensions in arcade</issue_title> <issue_description>I just noticed that aspnetcore has xunitextensions for various use-cases: https://github.com/aspnet/Extensions/tree/master/src/TestingUtils/Microsoft.AspNetCore.Testing/src/xunit. We do have the same in corefx and partner repositories: https://github.com/dotnet/arcade/tree/master/src/Microsoft.DotNet.XUnitExtensions

We should converge both and remove the duplication here. </issue_description>

<agent_instructions>Port all the tests from custom test helpers that can be found in test/TestUtilities/TestUtilities.csproj project to Microsoft.DotNet.XUnitExtensions NuGet package. Remove custom helpers.</agent_instructions>

Comments on the Issue (you are @copilot in this section)

@rynowak That would be cool. Have you done any analysis about the differences/commonalities between what's here and in arcade? @ViktorHofer Yeah I did a bit of digging. https://github.com/dotnet/arcade/blob/master/src/Microsoft.DotNet.XUnitExtensions/src/SkippedTestCase.cs is a 1:1 duplicate. Everything else should be beneficial for you but it seems you are using a slightly different attribute schema. You would probably need to change all your test data attributes to what we use in corefx/coreclr. Everything should be there with some tweaks. That said I think the migration is a ton of work given the amount of test code. @ericstj @joperezr -- @adamsitnik brought this up today. With more projects added to extensions it may be relevant again. There is a divergence between the infra we use in runtime and that which is used in extensions and aspnetcore. Do you see value in converging them to have a consistent set of tools used for building tests in our dotnet product repos? @adamsitnik cc @ViktorHofer who suggested in an offline conversation that we should aim for moving to xUnit v3 which provides plenty of these features natively @stephentoub > cc [@ViktorHofer](https://github.com/ViktorHofer) who suggested in an offline conversation that we should aim for moving to xUnit v3 which provides plenty of these features natively

Longer-term, absolutely. Short term, that is likely a non-trivial task; we should not block on that.</comment_new>

@copilot Please solve following build errors:

Fixed in commit 2f71906. Completed the migration by:

  • Converting MarkItDownConditionAttribute from ITestCondition interface to static helper class
  • Updating MarkItDownReaderTests to use ConditionalFact with static property reference
