I am working on an Ionic/Angular project and tried switching from Karma to Jest for my testing.
The following test was running fine before the switch:

import {TestBed, inject, async} from '@angular/core/testing';

import { TreasureTableService } from './treasure-table.service';

import {PapaParseModule} from 'ngx-papaparse';

import {HttpClientModule} from '@angular/common/http';



describe('TreasureTableService', () => {

  beforeEach(() => {

    TestBed.configureTestingModule({

      imports: [HttpClientModule, PapaParseModule]

    });

  });



  beforeEach(inject([TreasureTableService], s => {

    treasureTableService = s;

  }));



  it('should get treasure type list', async() => {

    let result: string = await treasureTableService.getTreasureTypeList();

    expect(result).toContain("A");

    expect(result.length).toBe(33);

  });

});

After I switched to Jest I got the following error:

    console.error node_modules/jsdom/lib/jsdom/virtual-console.js:29

    Error: Error: connect ECONNREFUSED 127.0.0.1:80

        at ClientRequest.emit (events.js:211:7)

Anyone got an idea what the problem could be?

EDIT:
After I stopped using the HttpClientModule and switched to the HttpClientTestingModule the connection Error went away but now I have problem with the async call:

Timeout - Async callback was not invoked within the 5000ms timeout specified by jest.setTimeout.
