The @nixos_org integration tests have always been a fantastic tool - We just made them even faster and much simpler to run! 🚀 By adding a new lightweight container backend to the test driver, you can now run your suites on standard, non-KVM VMs. 👇
Here is what the new container backend brings to your NixOS workflow:
⚡ Blazing Fast Execution: How fast? Booting two machines, letting them ping each other, and tearing them down now takes ~3 seconds!
💸 Run Anywhere (Cheaper!): You no longer need bare-metal KVM-enabled hosts. Your tests can now run seamlessly on cheap, standard VMs.
🎮 GPU Testing Support: Hardware acceleration is now accessible. You can finally test GPU-dependent workloads directly inside your integration tests!
Curious how it works under the hood and how to enable it in your projects? Dive into our latest article and try it out for yourself!

@jgalowicz @nixos_org That's awesome and may be ideal for the Home Manager integration tests!

@jgalowicz @nixos_org Oh my! I had the thought floating around my head why we don't simply use namespaces for all tests except the ones that test the kernel specifically. Well, I know the answer now; very cool to see this!

@jgalowicz @nixos_org why is there a Vectron in my NixOS post?

@jgalowicz@functional.cafe "on standard, non-KVM VMs", you mean non-VMs though? @nixos_org@chaos.social
