📝 Walkthrough

Walkthrough

The NUnit package version changes to 5.0.0. Analyzer detection, test assembly references, generated migration snippets, and migration documentation are updated for NUnit 5.

Changes

NUnit 5 migration support

Layer / File(s)	Summary
NUnit package and test assembly setup Directory.Packages.props, tests/TUnit.Analyzers.Tests/TUnit.Analyzers.Tests.csproj, tests/TUnit.Analyzers.Tests/NUnitMigrationAnalyzerTests.cs	The central NUnit package version changes to 5.0.0. The test project copies NUnit framework and legacy assemblies to its output. Analyzer tests use those assembly paths and report a FileNotFoundException with the expected path and build instruction if an assembly is missing.
Analyzer and migration examples src/TUnit.Analyzers/Migrators/NUnitMigrationAnalyzer.cs, tools/TUnit.DocSnippetGenerator/Program.cs, docs/docs/migration/nunit.md	The analyzer recognizes NUnit.Framework.StringAssert. Generated snippets resolve CollectionAssert and StringAssert from NUnit.Framework. The NUnit 3/4 documentation example omits await from Assert.ThrowsAsync; the TUnit example continues to use await.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Other

Merge Risk: ⚪ Minimal · up to e9723

The NUnit 5 update preserves the repository’s inspected benchmark and analyzer-test workflows, and the generated migration snippets use NUnit 5 namespaces. No concrete user-facing or build/test regression remains, so the change is ready to merge after normal checks.

_{A rabbit checks the NUnit trail,
With framework names now set to scale.
The snippets hop to namespaces new,
Test assemblies join the queue.
One less await marks the page,
And version five turns the stage.}
