What is TUnitMigrator?

TUnitMigrator is a C# .NET tool that automates migrating test projects from MSTest, NUnit, xUnit, or xUnit v3 to TUnit in one CLI command: `tunit-migrate /path/to/repo`. It strips old packages like MSTest.TestFramework or xunit.runner.visualstudio, adds the latest TUnit from NuGet, swaps framework extensions (e.g., Verify.MSTest to Verify.TUnit), updates csproj files to set OutputType=Exe, tweaks GitHub Actions .NET YAML for dotnet test, relocates global.json to root with Microsoft.Testing.Platform runner, and runs dotnet format analyzers to rewrite test attributes and assertions. Requires Central Package Management via Directory.Packages.props.

Why is it gaining traction?

Unlike manual migrations or basic package swappers, it handles the full stack—packages, project files, CI workflows, SDK configs, and code—saving hours on .NET GitHub repositories. Developers dig the NuGet-aware extension discovery and analyzer-driven code fixes that keep projects compiling mid-process. As a lightweight dotnet tool installable on Windows, Linux, Debian, or Ubuntu, it slots into any .NET GitHub runtime or SDK setup without bloat.

Who should use this?

.NET backend devs or library authors maintaining large test suites in MSTest/NUnit/xUnit on GitHub, especially those already using Central Package Management and GitHub Actions .NET workflows. Ideal for teams evaluating TUnit's speed and built-in coverage in .NET GitHub projects, or cleaning up legacy tests during .NET upgrades.

Verdict

Grab it if you're on TUnit's migration path—docs are clear with official guides, tests cover all scenarios, and it works out of the box as a .NET toolbox staple. With just 11 stars and 1.0% credibility score, it's early but mature enough for non-prod repos; test on a branch first.
