MRE for "Aborting `signal` of server.lister method before actual listeting begin put a `listen` promise into a floating state"
// add into test/server.test.js
await t.test('listen should not start server if already aborted 2', async (t) => {
t.plan(2)
const controller = new AbortController()
controller.abort(new Error('aborting before actual start'))
const fastify = Fastify()
try {
// promise returning by fastify.listen is in "floating" state
await fastify.listen({ port: 1234, signal: controller.signal })

String templates is not so good, as it can be :( . string_template_idea.js looks much better

const crypto = require('crypto');
const color = require('ansi-color').set;
const stringUtils = require('./string.es6');
const DATABASE_NAME = 'test123'
