The NixOS Integration Test Driver is evolving. This talk dives into recent architectural changes that separate the test frontend from the virtualization backend. We will demonstrate how this enables running tests in lightweight containers, unlocking GPU/CUDA testing inside the sandbox, and drastically reducing CI overhead. Learn how the new architecture works, how to utilize the VSOCK-based interactive mode, and what the future holds for NixOS testing.
