Testing Angular Http services via Jasmine / Karma

For a series of reasons I would like to be able to test some Http services (not via mock) using Jasmine / Karma support of Angualar.

If I use the following code

beforeEach(() => {
    TestBed.configureTestingModule({
      providers: [],
      imports: [
        HttpModule
      ]
    });
    .......

tests fail with the following message printed on Karma browser

Error: No provider for Http!
Error: DI Error
    at NoProviderError.ZoneAwareError (http://localhost:9876/base/src/polyfills.ts?1adeefc4ae1dd1c3f12dac836469652bbacab66c:2054:33)

.......

Any suggestion on how to fix it would be very much appreciated

You may need to configure the provider for Http. For example:

TestBed.configureTestingModule({
  providers: [ { provide: Http, useClass: Http } ],

If that doesn't do the trick, please share your imports and any earlier code in the test spec.
