Run your app in headless mode for testing

This can be useful for running app simulations during integration tests without spawning a window which can be problematic in a testing environment.

use bevy::prelude::*;
use bevy::render::{
  settings::{RenderCreation, WgpuSettings},
  RenderPlugin,
};

fn main() {
  App::new()
    .add_plugins(DefaultPlugins.set(RenderPlugin {
      synchronous_pipeline_compilation: true,
      render_creation: RenderCreation::Automatic(WgpuSettings {
        backends: None,
        ..default()
      }),
    }))
    .run();
}

This will load everything your game would normally have, but then not run any of the rendering pipeline.
