A modern, flexible and fast testing framework for .NET 8 and up. With Native AOT and Trimmed Single File application support included!
TUnit is designed to aid with all testing types:
Unit
Integration
Acceptance
and more!
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 on the Preview version currently.
Install the latest preview version
Open Visual Studio and go to Tools > Manage Preview Features
Enable "Use testing platform server mode"
Rider
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
Property injection
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
Tests can depend on other tests to form chains, useful for if one test depends on state from another action. While not recommended for unit tests, this can be useful in integration testing where state matters
Easy to read assertions - though you're also free to use whichever assertion library you like
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
Dependency injection support (See here )
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);
}

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.
Prerelease You'll notice that version 1.0 isn't out yet. While this framework is mostly feature complete, I'm waiting for a few things:
Full Rider support for all features
Full VS support for all features
Open to feedback on existing features
Open to ideas on new features
As such, the API may change. I'll try to limit this but it's a possibility.
