meta: Begin writing tests in Nix Now that I've figured out how to dynamically import modules and use those modules as outputs, the next step is to ensure that these modules work as intended when being used by end users. NixOS offers a built-in testing solution that enables us to conveniently spin up virtual machines with a given configuration, then verify their correctness through python scripting. The lib.nix file in particular is based on Jörg Thalheim's very useful blog post that explains how to use the built-in testing functionality with Nix flakes, which isn't covered in official documentation.
