Get best practices for TUnit unit testing, including data-driven tests.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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., `CalculatorTests` for `Calculator`) - Use .NET SDK test commands: `dotnet test` for 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 - Use `[Before(Class)]` and `[After(Class)]` for shared context between tests in a class - Use `[Before(Assembly)]` and `[After(Assembly)]` for shared context across test classes - TUnit supports advanced lifecycle hooks like `[Before(TestSession)]` and `[After(TestSession)]` ## Standard Tests - Keep tests focused on a single behaviour …

How to install
mdr add marielynneblock/arcanum-artifex/csharp-tunit@sha256:7132da7f7debdafcThe line at the top of this page pins the label git:20260710.0115f49, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
