csharp-tunit
Best practices for writing unit tests with TUnit, including data-driven and advanced testing patterns.
What it does
- Use a separate test project with naming convention [ProjectName].Tests
- Reference TUnit package and TUnit.Assertions for fluent assertions
- Create test classes that match the classes being tested (e.g., CalculatorTests for Calculator)
- Use .NET SDK test commands: dotnet test for running tests
- TUnit requires .NET 8.0 or higher
- No test class attributes required (like xUnit/NUnit)
- Use [Test] attribute for test methods (not [Fact] like xUnit)
Requirements & configuration
- TUnit requires .NET 8.0 or higher
- TUnit runs tests in parallel by default (unlike xUnit which requires explicit configuration)
