Test Platform and Framework Detection
Determine which test platform (VSTest or Microsoft.Testing.Platform) and which test framework (MSTest, xUnit, NUnit, TUnit) a project uses.
Detection files to always check (in order): global.json → .csproj → Directory.Build.props → Directory.Packages.props
Detecting the test framework
Read the .csproj file and Directory.Build.props / Directory.Packages.props (for centrally managed dependencies) and look for:
| Package or SDK reference | Framework |
|---|---|
MSTest (metapackage, recommended) or <Sdk Name="MSTest.Sdk"> |
MSTest |
MSTest.TestFramework + MSTest.TestAdapter |
MSTest (also valid for v3/v4) |
xunit, xunit.v3, xunit.v3.mtp-v1, xunit.v3.mtp-v2, xunit.v3.core.mtp-v1, xunit.v3.core.mtp-v2 |
xUnit |
NUnit + NUnit3TestAdapter |
NUnit |
TUnit |
TUnit (MTP only) |
