        using the program in the test derivation's `.driverInteractive` attribute.

        When they are, the configuration will include anything set in this submodule.

        You can set any top-level test option here.

        Example test module:

        ```nix
        { config, lib, ... }: {

          nodes.rabbitmq = {
            services.rabbitmq.enable = true;
          };

          # When running interactively ...
          interactive.nodes.rabbitmq = {
            # ... enable the web ui.
            services.rabbitmq.managementPlugin.enable = true;
          };
        }
        ```
