spec.ts for http get service is not working.

[rushikeshsarode]

Following is my 'user.service.ts' file which uses http get to receive data from users.json file :

import {Injectable} from '@angular/core'; import { IUser } from './userInterface'; import { Http, Response } from '@angular/http'; import{ Observable } from 'rxjs/Observable'; @Injectable()

export class UserService { private _productUrl = '../app/users/users.json'; constructor(private _http: Http) {} getUsers(): Observable { return this._http.get(this._productUrl) .map((response: Response) => response.json()); } }

I have following 'user.service.spec.ts' file to test the above service :

import { describe, expect, beforeEach, it, inject, beforeEachProviders } from '@angular/core/testing'; import { UserService } from './user.service'; import { HTTP_PROVIDERS } from '@angular/http';

export function main() {

describe('UserService test', () => { let service: UserService;

//setup beforeEachProviders(() => { return[ HTTP_PROVIDERS, //provide(XHRBackend, {useClass: MockBackend}), UserService ]; });

beforeEach(inject([UserService], (l:any) => { service = l; }));

it('should return the list of users', () => { service.getUsers().subscribe(x => { expect(x).toEqual(jasmine.any(Array)); }); }); }); }

Any guess why this is not working and throws error (attached screenshot) when I run 'npm test'... Thanks in advance.
