Use nix build inside of nixos test

Help

Is it possible to successfully run nix build in an nixosTest? I’m getting No such file or directory errors in the build process.

I try to implement this for the test in this pr Init flake-auto-upgrade by StillerHarpo · Pull Request #229085 · NixOS/nixpkgs · GitHub

This is the derivation I came up with

      derivation {
        name = "attr1";
        builder = "${pkgs.bash}/bin/bash";
        args = [ ${
          pkgs.writeScript "attr1"
          "${pkgs.coreutils}/bin/mkdir $out; ${pkgs.coreutils}/bin/touch $out/result1"
        } ];
        system="x86_64-linux";
      }
