🚀 The Modern Testing Framework for .NET

TUnit is a next-generation testing framework for C# that outpaces traditional frameworks with source-generated tests, parallel execution by default, and Native AOT support. Built on the modern Microsoft.Testing.Platform, TUnit delivers faster test runs, better developer experience, and unmatched flexibility.

⚡ Why Choose 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	✅ Full Native AOT & trimming
Test Dependencies	❌ Not supported	✅ `[DependsOn]` chains
Resource Management	❌ Manual lifecycle	✅ Intelligent cleanup

⚡ Parallel by Default - Tests run concurrently with intelligent dependency management

🎯 Compile-Time Discovery - Know your test structure before runtime

🔧 Modern .NET Ready - Native AOT, trimming, and latest .NET features

🎭 Extensible - Customize data sources, attributes, and test behavior

📚 Complete Documentation & Learning Center

🚀 New to TUnit? Start with our Getting Started Guide

📝 Simple Test Example

[Test]
public async Task User_Creation_Should_Set_Timestamp()
{
    // Arrange
    var userService = new UserService();

    // Act
    var user = await userService.CreateUserAsync("[email protected]");

    // Assert - TUnit's fluent assertions
    await Assert.That(user.CreatedAt)
        .IsEqualTo(DateTime.Now)
        .Within(TimeSpan.FromMinutes(1));

    await Assert.That(user.Email)
        .IsEqualTo("[email protected]");
}

🎯 Data-Driven Testing

[Test]
[Arguments("[email protected]", "ValidPassword123")]
[Arguments("[email protected]", "AnotherPassword456")]
[Arguments("[email protected]", "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
}

🔧 Smart 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 });
}

🎯 Perfect For Every Testing Scenario

🧪 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);
}

Fast, isolated, and reliable

🔗 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();
}

Stateful workflows made simple

⚡ 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);
}

Built-in performance testing

🚀 What Makes TUnit Different?

Compile-Time Intelligence

Tests are discovered at build time, not runtime - enabling faster discovery, better IDE integration, and precise resource lifecycle management.

Parallel-First Architecture

Built for concurrency from day one with [DependsOn] for test chains, [ParallelLimit] for resource control, and intelligent scheduling.

Extensible by Design

The DataSourceGenerator<T> pattern and custom attribute system let you extend TUnit's capabilities without modifying core framework code.
