DurableTaskTestHost - Testing Durable Orchestrations In-Process

DurableTaskTestHost is a simple API for testing your durable task orchestrations and activities in-process without requiring any external backend.

Supports both class-based and function-based syntax.

Quick Start

Configure options

var options = new DurableTaskTestHostOptions
{
    Port = 31000,                  // Optional: specific port (random by default)
    LoggerFactory = myLoggerFactory // Optional: pass logger factory for logging
};

await using var testHost = await DurableTaskTestHost.StartAsync(registry =>
{
    // Class-based
    registry.AddOrchestrator<MyOrchestrator>();
    registry.AddActivity<MyActivity>();
    
    // Function-based
    registry.AddOrchestratorFunc("MyFunc", (ctx, input) => Task.FromResult("done"));
    registry.AddActivityFunc("MyActivity", (ctx, input) => Task.FromResult("result"));
});

Test

string instanceId = await testHost.Client.ScheduleNewOrchestrationInstanceAsync("MyOrchestrator");
var result = await testHost.Client.WaitForInstanceCompletionAsync(instanceId);

More Samples

See BasicOrchestrationTests.cs for complete samples showing both class-syntax and function-syntax orchestrations.
