🚀 The Modern Testing Framework for .NET
TUnit is a modern testing framework for .NET that uses source-generated tests , parallel execution by default , and Native AOT support . Built on Microsoft.Testing.Platform, it's faster than traditional reflection-based frameworks and gives you more control over how your tests run.

Why TUnit? Feature Traditional Frameworks TUnit Test Discovery ❌ Runtime reflection ✅ Compile-time generation Execution Speed ❌ Sequential by default ✅ Parallel by default Modern .NET ⚠️ Limited AOT support ✅ Native AOT & trimming Test Dependencies ❌ Not supported ✅ [DependsOn] chains Resource Management ❌ Manual lifecycle ✅ Automatic cleanup
Parallel by Default - Tests run concurrently with dependency management
Compile-Time Discovery - Test structure is known before runtime
Modern .NET Ready - Native AOT, trimming, and latest .NET features
Extensible - Customize data sources, attributes, and test behavior
Quick Start
Using the Project Template (Recommended) dotnet new install TUnit.Templates
dotnet new TUnit -n "MyTestProject"
Manual Installation dotnet add package TUnit --prerelease
Key Features
Source-generated tests (no reflection)
Parallel execution by default
Native AOT & trimming support
Optimized for speed
Test dependencies with [DependsOn]
Parallel limits & custom scheduling
Built-in analyzers & compile-time checks
Custom attributes & extensible conditions
Multiple data sources ([Arguments], [Matrix], [ClassData])
Fluent async assertions
Retry logic & conditional execution
Test metadata & context
Full dependency injection support
Lifecycle hooks
IDE integration (VS, Rider, VS Code)
Documentation & examples
Simple Test Example [Test]
public async Task User_Creation_Should_Set_Timestamp()
{
// Arrange
var userService = new UserService();
// Act
var user = await userService.CreateUserAsync("john.doe@example.com");
// Assert - TUnit's fluent assertions
await Assert.That(user.CreatedAt)
.IsEqualTo(DateTime.Now)
.Within(TimeSpan.FromMinutes(1));
await Assert.That(user.Email)
.IsEqualTo("john.doe@example.com");
}
Data-Driven Testing [Test]
[Arguments("user1@test.com", "ValidPassword123")]
[Arguments("user2@test.com", "AnotherPassword456")]
[Arguments("admin@test.com", "AdminPass789")]
public async Task User_Login_Should_Succeed(string email, string password)
{
var result = await authService.LoginAsync(email, password);
await Assert.That(result.IsSuccess).IsTrue();
}
// Matrix testing - tests all combinations
[Test]
[MatrixDataSource]
public async Task Database_Operations_Work(
[Matrix("Create", "Update", "Delete")] string operation,
[Matrix("User", "Product", "Order")] string entity)
{
await Assert.That(await ExecuteOperation(operation, entity))
.IsTrue();
}
Advanced Test Orchestration [Before(Class)]
public static async Task SetupDatabase(ClassHookContext context)
{
await DatabaseHelper.InitializeAsync();
}
[Test, DisplayName("Register a new account")]
[MethodDataSource(nameof(GetTestUsers))]
public async Task Register_User(string username, string password)
{
// Test implementation
}
[Test, DependsOn(nameof(Register_User))]
[Retry(3)] // Retry on failure
public async Task Login_With_Registered_User(string username, string password)
{
// This test runs after Register_User completes
}
[Test]
[ParallelLimit<LoadTestParallelLimit>] // Custom parallel control
[Repeat(100)] // Run 100 times
public async Task Load_Test_Homepage()
{
// Performance testing
}
// Custom attributes
[Test, WindowsOnly, RetryOnHttpError(5)]
public async Task Windows_Specific_Feature()
{
// Platform-specific test with custom retry logic
}
public class LoadTestParallelLimit : IParallelLimit
{
public int Limit => 10; // Limit to 10 concurrent executions
}
Custom Test Control // Custom conditional execution
public class WindowsOnlyAttribute : SkipAttribute
{
public WindowsOnlyAttribute() : base("Windows only test") { }
public override Task<bool> ShouldSkip(TestContext testContext)
=> Task.FromResult(!OperatingSystem.IsWindows());
}
// Custom retry logic
public class RetryOnHttpErrorAttribute : RetryAttribute
{
public RetryOnHttpErrorAttribute(int times) : base(times) { }
public override Task<bool> ShouldRetry(TestInformation testInformation,
Exception exception, int currentRetryCount)
=> Task.FromResult(exception is HttpRequestException { StatusCode: HttpStatusCode.ServiceUnavailable });
}
Common Use Cases
Unit Testing [Test]
[Arguments(1, 2, 3)]
[Arguments(5, 10, 15)]
public async Task Calculate_Sum(int a, int b, int expected)
{
await Assert.That(Calculator.Add(a, b))
.IsEqualTo(expected);
}
Integration Testing [Test, DependsOn(nameof(CreateUser))]
public async Task Login_After_Registration()
{
// Runs after CreateUser completes
var result = await authService.Login(user);
await Assert.That(result.IsSuccess).IsTrue();
}
Load Testing [Test]
[ParallelLimit<LoadTestLimit>]
[Repeat(1000)]
public async Task API_Handles_Concurrent_Requests()
{
await Assert.That(await httpClient.GetAsync("/api/health"))
.HasStatusCode(HttpStatusCode.OK);
}
What Makes TUnit Different?
Compile-Time Test Discovery Tests are discovered at build time, not runtime. This means faster discovery, better IDE integration, and more predictable resource management.
Parallel by Default Tests run in parallel by default. Use [DependsOn] to chain tests together, and [ParallelLimit] to control resource usage.
Extensible The DataSourceGenerator<T> pattern and custom attribute system let you extend TUnit without modifying the framework.
Community & Ecosystem
Resources
IDE Support TUnit works with all major .NET IDEs:
Visual Studio (2022 17.13+) ✅ Fully supported - No additional configuration needed for latest versions
⚙️ Earlier versions : Enable "Use testing platform server mode" in Tools > Manage Preview Features
JetBrains Rider ⚙️ Setup : Enable "Testing Platform support" in Settings > Build, Execution, Deployment > Unit Testing > Testing Platform
Visual Studio Code ⚙️ Setup : Install C# Dev Kit and enable "Use Testing Platform Protocol"
Command Line ✅ Full CLI support - Works with dotnet test, dotnet run, and direct executable execution
Package Options Package Use Case TUnitStart here - Complete testing framework (includes Core + Engine + Assertions)TUnit.CoreTest libraries and shared components (no execution engine) TUnit.EngineTest execution engine and adapter (for test projects) TUnit.AssertionsStandalone assertions (works with any test framework) TUnit.PlaywrightPlaywright integration with automatic lifecycle management
Migration from Other Frameworks Coming from NUnit or xUnit? TUnit uses familiar syntax with some additions:
// TUnit test with dependency management and retries
[Test]
[Arguments("value1")]
[Arguments("value2")]
[Retry(3)]
[ParallelLimit<CustomLimit>]
public async Task Modern_TUnit_Test(string value) { }
Current Status The API is mostly stable, but may have some changes based on feedback before the v1.0 release.
Getting Started # Create a new test project
dotnet new install TUnit.Templates && dotnet new TUnit -n "MyTestProject"
