A test we don't need any longer which I wanted to retain for reference

productDateForge.test.js

const product = {
  name: 'Our testing product',
  description: 'a product object used for testing',
  type: 'TICKET',
  createdAt: '2020-11-20T15:03:35.219Z',
  createdBy: 'auth0|0',
  lastUpdatedAt: '2020-11-20T15:03:35.219Z',
  lastUpdatedBy: 'auth0|0',
};

const copy = {
  ...product,
};

describe('productDateForge tests', () => {
  let productDateForge;
  const originalEnv = process.env;

  beforeAll(() => {
    jest.resetModules();
    process.env = { ...originalEnv }; // puts a copy on process.env

    // Required for @thatconference/api
    process.env.INFLUX_TOKEN = 'TEST_INFLUX_TOKEN_VALUE';
    process.env.INFLUX_ORG_ID = 'TEST_INFLUX_ORG_ID_VALUE';
    process.env.INFLUX_BUCKET_ID = 'INFLUX_BUCKET_ID';
    process.env.INFLUX_HOST = 'INFLUX_HOST';

    productDateForge = require('../productDateForge').productDateForge;
  });

  afterAll(() => {
    process.env = originalEnv;
  });

  describe('productDateForge should not mutate non-date fields', () => {
    it('type, createdBy and lastUpdatedBy will remain the same', () => {
      const forged = productDateForge(product);
      expect(forged.type).toBe(copy.type);
