SnowBank.Testing.Framework

An SDK for writing integration tests for distributed .NET applications: spin up several simulated hosts on an in-memory virtual network inside a single test, with all of their traffic routed in-process, and no real sockets, ports, or containers.

Concept

Derive your fixture from DistributedTest and describe a topology with MakeItSo: virtual LANs, web hosts, agents and services. Each one is a real host, built the way your production hosts are (DI, minimal APIs, SignalR, ...), but wired onto a virtual network instead of real sockets. The framework records everything into a single, ordered timeline journal that is printed with the test output, so a failure spread across several hosts reads as one coherent story.

How to use

dotnet add package SnowBank.Testing.Framework

public class MyFacts : DistributedTest
{
    [Test]
    public async Task Two_Hosts_On_A_Virtual_Lan()
    {
        var context = await MakeItSo(env => env.AddSimpleLan(lan =>
        {
            // a simulated web host, configured like a real one
            lan.WithMinimalWebHost("WEB", host =>
            {
                host.ConfigureApplication(app => app.MapGet("/ping", () => "pong"));
            });
        }));

        var web = context.GetWebHost("WEB");

        // `web` is a real host reachable over the virtual network; exercise it from another
        // host, an HTTP client, or a browser (see SnowBank.Testing.Framework.Playwright)
        Assert.That(web.GetUri("/ping"), Is.Not.Null);
    }
}

Add a real Chromium to the same network with the companion SnowBank.Testing.Framework.Playwright package (lan.WithPlaywrightBrowser(...)).

For the timeline-journal format, per-host log levels, always-on HTTP packet capture and the other diagnostics, see the snowbank-distributed-testing guidance in the repository.
