TUnit v0.1.762 — nugetz
thomhurst/ TUnit v0.1.762 ✓ Verified .NET 8.0 .NET 9.0 .NET 10.0 .NET Std2.0
A .NET Testing Framework
Get Started dotnet CLI PackageReference Package Manager
$ dotnet add package TUnitReadme TUnit
A modern, flexible and fast testing framework for .NET 8 and up. With Native AOT and Trimmed Single File application support included!
Documentation
See here: https://thomhurst.github.io/TUnit/
IDE
TUnit is built on top of the newer Microsoft.Testing.Platform, as opposed to the older VSTest platform. Because the infrastructure behind the scenes is new and different, you may need to enable some settings. This should just be a one time thing.
Visual Studio
Visual Studio is supported.
Rider
Rider is supported. The Enable Testing Platform support option must be selected in Settings > Build, Execution, Deployment > Unit Testing > VSTest.
VS Code Visual Studio Code is supported.
Install the extension Name: C# Dev Kit
Go to the C# Dev Kit extension's settings
Enable Dotnet > Test Window > Use Testing Platform Protocol
CLI dotnet CLI - Fully supported. Tests should be runnable with dotnet test, dotnet run, dotnet exec or executing an executable directly. See the docs for more information!
Features
Native AOT / Trimmed Single File application support
Source generated tests
Dependency injection support (See here )
Full async support
Parallel by default, with mechanisms to:
Run specific tests completely on their own
Run specific tests not in parallel with other specific tests
Limit the parallel limit on a per-test, class or assembly level
Test ordering (if running not in parallel)
Tests can depend on other tests to form chains, useful for if one test depends on state from another action
Easy to read assertions
Injectable test data via classes, methods, compile-time args, or matrices
Hooks before and after:
TestDiscover
TestSession
Assembly
Class
Test
Designed to avoid common pitfalls such as leaky test states
Ability to view and interrogate metadata and results from various assembly/class/test context objects
Installation dotnet add package TUnit --prerelease
Example test private static readonly TimeOnly Midnight = TimeOnly.FromTimeSpan(TimeSpan.Zero);
private static readonly TimeOnly Noon = TimeOnly.FromTimeSpan(TimeSpan.FromHours(12));
[Test]
public async Task IsMorning()
{
var time = GetTime();
await Assert.That(time).IsAfterOrEqualTo(Midnight)
.And.IsBefore(Noon);
}
or with more complex test orchestration needs

}
Motivations TUnit is inspired by NUnit and xUnit - two of the most popular testing frameworks for .NET.
It aims to build upon the useful features of both while trying to address any pain points that they may have.
