🚀 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.

✅ 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
🏁 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 🚀 Performance & Modern Platform
🔥 Source-generated tests (no reflection)
⚡ Parallel execution by default
🚀 Native AOT & trimming support
📈 Optimized for performance
🔗 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
🔄 Smart retry logic & conditional execution
📝 Rich test metadata & context
💉 Full dependency injection support
🪝 Comprehensive lifecycle hooks
🎯 IDE integration (VS, Rider, VS Code)
📚 Extensive 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
}
🔧 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.
