is there a way to run an http server *

is there a way to run an http server within a test. For example I have this snippet: 
import { describe, expect, it } from 'vitest';
import { Miniflare } from 'miniflare';

describe('MiniflareFun', () => {
  it('end-to-end', async () => {
    const mf = new Miniflare({
      modules: true,
      script: `
        export default {
          async fetch(request, env, ctx) {
            return new Response("Hello Miniflare!");
          }
        }
        `,
    });

    const res = await mf.dispatchFetch('http://localhost:8787/');
    console.log(await res.text()); // Hello Miniflare!
    await mf.dispose();
    expect(true).toBe(true);
  });
});
import { describe, expect, it } from 'vitest';
import { Miniflare } from 'miniflare';

describe('MiniflareFun', () => {
  it('end-to-end', async () => {
    const mf = new Miniflare({
      modules: true,
      script: `
        export default {
          async fetch(request, env, ctx) {
            return new Response("Hello Miniflare!");
          }
        }
        `,
    });

    const res = await mf.dispatchFetch('http://localhost:8787/');
    console.log(await res.text()); // Hello Miniflare!
    await mf.dispose();
    expect(true).toBe(true);
  });
});
But then I get this error: 
bash Error: No such module "node:os".
bash Error: No such module "node:os".
I cannot use fetchmock for this, it needs to be some sort of HTTP server on an arbitrary port.

Actually i can use fetch mock with persistence, that will work for my needs, thanks!
