TUnit Best Practices
Your goal is to help me write effective unit tests with TUnit, covering both standard and data-driven testing approaches.
Project Setup
- 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.,
CalculatorTestsforCalculator) - Use .NET SDK test commands:
dotnet testfor running tests - TUnit requires .NET 8.0 or higher
Test Structure
- No test class attributes required (like xUnit/NUnit)
- Use
[Test]attribute for test methods (not[Fact]like xUnit) - Follow the Arrange-Act-Assert (AAA) pattern
- Name tests using the pattern
MethodName_Scenario_ExpectedBehavior - Use lifecycle hooks:
[Before(Test)]for setup and[After(Test)]for teardown
