Sample spec that uses appInjector() and a service

persos.service.spec.ts

import {it, describe, expect, inject, beforeEach, beforeEachProviders} from 'angular2/testing'
import {PersonService, PERSON_SERVICE_PROVIDERS, personServiceLoadedPromise} from './person.service'
// Contents of person.service.ts
//@Injectable()
//export class PersonService {
//  constructor(private _http: Http) { }
//
//  init(): Promise<boolean>{
//    return this._http.get('myurl').toPromise();
//  }
//}
//
//function personServiceLoadedPromise(next, prev): Promise<boolean>{
//  return appInjector().get(PersonService).init();
//}
//
//const PERSON_SERVICE_PROVIDERS = [
//  PersonService,
//  HTTP_PROVIDERS
//];
import {appInjector} from "./app-injector";
import {Injector} from 'angular2/core'

describe('PersonService',()=>{
  describe('#personServiceLoadedPromise',()=> {
    beforeEachProviders(()=>[PERSON_SERVICE_PROVIDERS]);
    beforeEach(inject([PersonService],()=>{
      appInjector(Injector.resolveAndCreate([PERSON_SERVICE_PROVIDERS]));
    }));

    it('calls #init()', ()=> {

      personServiceLoadedPromise(null,null);

      expect(service.init).toHaveBeenCalled();
    });
