How to mock a service which has http requests?

Hey,
I know this is not the right platform to ask this, but on right platform, there is no reply from anyone.
How to mock a service which contains http requests?
For eg:

I want to test my provider class, so I am unable to write spec for providers.
My provider is as follows:
**service.ts**

```
//imports are done correctly.
@Injectable()
export class Service {
constructor(private http: Http) { }
getGoogle():Observable {
console.log("Inside service");
return this.http.get('https://jsonplaceholder.typicode.com/posts/1');
} }

```
My page.ts is as follows:

**page.ts**

```
**//imports are done correctly.

export class Page1 {
constructor(private service: Service, private navCtrl: NavController) { }
async get() { console.log("inside get method");
const data = await this.service.getGoogle().toPromise();
console.log('The response is' , data);
} }

```
**service.spec.ts**

```
//imports are done correctly

describe('Service', () =>
{ let comp: Service;
let fixture: ComponentFixture;
let de: DebugElement;
beforeEach(async(() => {
TestBed.configureTestingModule({
declarations: [],
imports: [
IonicModule.forRoot(Service)
],
providers: [Http]

}).compileComponents();

}));

beforeEach(() => {

fixture = TestBed.createComponent(Service);
comp = fixture.componentInstance;
de = fixture.debugElement;
});

afterEach(() => {

fixture.destroy();

});

it('test the http request to te server', ()=>{

//code to test http request of the Service class });

});**
```

All the imports are done correctly, only the logic to test the `getGoogle() `with `http.get() `needs to be tested.Please help or share some links or tell me some steps in order to do testing of this ionic2 content.

Thanks
