How to Unit Test Angular2 / TypeScript HTTPService WITHOUT MOCK

import {Injectable} from '@angular/core';
import {Http} from '@angular/http';

export class HttpService {
  result: any;

  constructor(private http:Http) {

   public postRequest(){
       return this.http.get('');    

Above is my code, here is my Test:

I do not want to mock anything, just test the real http connection.

Edit - New service.spec file:

import {beforeEachProviders, beforeEach, it, describe, expect, inject} from '@angular/core/testing';
import {HttpService} from '../../providers/http-service/http-service';
import {TranslateService} from 'ng2-translate/ng2-translate';
import {Goal} from '../../providers/goal/goal';
import {NavController} from 'ionic-angular';
import {HTTP_PROVIDERS, Http} from '@angular/http';

describe('Http Service Test', () => {

      beforeEachProviders(() => {
        return [

    it('should return response when subscribed to postRequest',
        inject([HttpService], (httpService: HttpService) => {

            httpService.postRequest().subscribe((res) => {
                expect(res.text()).toBe('hello raja');

These are my errors in karma console:
