Webapplicationfactory on .NET wat we zoeken

Integration testing with Playwright just got easier

Sun, 08 Feb 2026 12:35:00 +0100

In a previous blog post, I introduced the NuGet package Nwwz.Mvc.Testing. This package was designed to make it possible to make the WebApplicationFactory listen on a rela port to that you can use it with Playwright.

The package implements a different WebApplicationFactory that spin up a Kestrel instance instead ot the in-memory TestServer.

With the release of .NET 10, this workaround is no longer necessary. Microsoft has introduced a native way to run WebApplicationFactory using Kestrel.

Simplifying integration testing with .NET and Playwright

In my earlier blog, Integration Testing with Playwright and Testcontainers, I shared how to use a WebApplicationFactory with TestContainers and Playwright to set up integration tests. While this approach works well, I encountered a problem: the setup inadvertently spins up two separate hosts, leading to unwanted behaviour.

Nwwz.Mvc.Testing

I am introducing NuGet package Nwwz.Mvc.Testing to solve those issue.It’s a simple helper to easily setup a .NET application fro integration testing while allowing a browser to connect to it.
