# NixOS Polytest

Allow for multiple nixpkgs evaluations within a "runTest" like environment

## Minimal example

```nix

{

  description = "Example poly nixpkgs tests";

  inputs = {

    nixpkgs-2311.url = "github:nixos/nixpkgs/nixos-23.11";

    nixpkgs-2405.url = "github:nixos/nixpkgs/nixos-24.05";

    poly-test.url = "github:jonringer/nixos-polytest";

  };

  outputs = { nixpkgs-2311, nixpkgs-2405, poly-test, self }: let

    # This can be a linux or darwin system

    hostPkgs = import nixpkgs-2311 { system = "x86_64-linux"; };

    runPolyTest = poly-test.lib.mkRunPolyTest hostPkgs;

  in {

    checks.x86_64-linux.example = runPolyTest {

      name = "example-polytest";

      testScript = ''

        start_all()

        foo.wait_for_unit("multi-user.target")

        bar.wait_for_unit("multi-user.target")

        

        foo.succeed("grep 23.11 /etc/os-release")

        bar.succeed("grep 24.05 /etc/os-release")

      '';

      nodes.a = {

        nixpkgsPath = toString nixpkgs-2311;

        specialArgs = { };

        modules = [ {

          system.name = "foo";

        }];

      };

      nodes.b = {

        nixpkgsPath = toString nixpkgs-2405;

        specialArgs = { };

        modules = [ {

          system.name = "bar";

        }];

      };

    };

  };

}

```
