xUnit.net
Free, open-source, community-focused unit-testing tool for the .NET Framework, .NET Core and .NET 5+, the default testing framework in new dotnet CLI templates.
Our Verdict
The right default for new .NET projects thanks to tight dotnet CLI integration and parallel-first design.
Pros
- Default in new dotnet CLI templates
- Clean fact/theory model without setup/teardown
- Strong parallelism by default
- Active community and frequent releases
Cons
- No Setup/TearDown attributes, constructor only
- Smaller parameterization toolkit than NUnit
- Migration from NUnit has friction
Best for: New .NET projects picking a framework aligned with Microsoft defaults
Not for: Teams with heavy NUnit investment in parameterized test suites
When to Use xUnit.net
Good fit if you need
- Default .NET unit testing framework for dotnet CLI projects
- Theory/InlineData for parameterized .NET test cases
