For example, to run the test +[`login.nix`](https://github.com/NixOS/nixpkgs/blob/master/nixos/tests/login.nix), +you do: + +```ShellSession +$ cd /my/git/clone/of/nixpkgs +$ nix-build -A nixosTests.login +``` + +After building/downloading all required dependencies, this will perform +a build that starts a QEMU/KVM virtual machine containing a NixOS +system. The virtual machine mounts the Nix store of the host; this makes +VM creation very fast, as no disk image needs to be created. Afterwards, +you can view a log of the test: + +```ShellSession +$ nix-store --read-log result +``` |
