dotnet-test-migration
Overview
Use this skill for .NET test migrations, including MSTest upgrades, xUnit upgrades, xUnit-to-MSTest conversions, and VSTest to Microsoft.Testing.Platform migrations using dotnet/skills.
Workflow
- Inventory test frameworks, adapters, assertions, fixtures, categories, parallelization, and CI runner behavior.
- Choose a migration sequence that keeps tests runnable after each slice.
- Convert framework attributes, assertions, lifecycle hooks, data tests, and runner configuration deliberately.
- Validate migrated tests with before-and-after command output where possible.
Guardrails
- Do not mix migration types without explaining the sequencing.
- Preserve test intent, filtering semantics, categories, and CI reporting.
- Call out unsupported framework features or manual follow-up work.
Expected Output
Return a test-migration plan or implementation with changed contracts, commands, and remaining gaps.
