angular2 testing using jasmine for subscribe method

Question

I have a spec code to test like this

 it(\'login test\', () => {

      const fixture = TestBed.createComponent(component);
      fixture.detectChanges();         


        

Answer 1

You need to mock the login function as follows:

let loginService: any = {
    login(): Observable {
        return Observable.of('you object');
    }
};

you might find the observable.if function undefined, so you need to import the observable this way:

import { Observable } from 'rxjs/Rx';
import 'rxjs/add/observable/of';
