Announcing the Stryker Playground

Explaining the intricacies of mutation testing to a co-worker or friend can be challenging. We believe the best way to grasp a new concept is through hands-on practice. While we already offer a quickstart guide, installing all the prerequisites can be quite cumbersome.

That is why we are happy to announce the Stryker Playground, bringing the Stryker.NET experience to the web!

🤔 How does this work?

You may have noticed the playground takes a while to load initially. That is because it's entirely client-side, powered by Blazor WebAssembly. Compiling the submitted code into an in-memory assembly is made possible by Roslyn, the .NET Compiler Platform. And, of course, the playground also depends on Stryker.NET for the instrumentation.

Thanks to the NUnit Lite Runner we're able to discover and execute tests contained inside in-memory assemblies.

🔮 What's on the horizon?

We're looking for ways to improve intellisense, which should make it easier to freely write code and discover available methods and variables. We would also like to introduce a diverse collection of templates, offering users challenges of varying difficulties.

And last but not least, supporting StrykerJs & Stryker4s is also on the roadmap!
