## `runNixOSTest` {#tester-runNixOSTest}
A helper function that behaves exactly like the NixOS `runTest`, except it also assigns this Nixpkgs package set as the `pkgs` of the test and makes the `nixpkgs.*` options read-only.
If your test is part of the Nixpkgs repository, or if you need a more general entrypoint, see ["Calling a test" in the NixOS manual](https://nixos.org/manual/nixos/stable/index.html#sec-calling-nixos-tests).
Example:
```nix
pkgs.testers.runNixOSTest ({ lib, ... }: {
name = "hello";
nodes.machine = { pkgs, ... }: {
environment.systemPackages = [ pkgs.hello ];
};
testScript = ''
machine.succeed("hello")
'';
})
```
## `nixosTest` {#tester-nixosTest} ## `nixosTest` {#tester-nixosTest}
Run a NixOS VM network test using this evaluation of Nixpkgs. Run a NixOS VM network test using this evaluation of Nixpkgs.
