Testing a service

Hello,

We've been trying to test a service which depends on the angular HTTP service but we can't seem to get this to work properly.
My code is as follows:

app.spec.ts:

/// <reference path="../../src/typings/_custom.d.ts" />

// Import necessary wrappers for Jasmine
import {
    beforeEachProviders,
    describe,
    expect,
    iit,
    inject,
    it,
    injectAsync,
    fakeAsync,
    TestComponentBuilder,
    tick
} from 'angular2/testing';
import { Component, provide} from 'angular2/angular2';
import {MockBackend, BaseRequestOptions, Http} from 'angular2/http';

// Load the implementations that should be tested
import { App } from '../../src/app/app';
import {InstrumentFactory} from "../../src/app/Factories/InstrumentFactory";

describe('App', () => {
    // provide our implementations or mocks to the dependency injector
    beforeEachProviders(() => [
        App,
        BaseRequestOptions,
        MockBackend,
        provide(Http, {useFactory:
            function(backend, defaultOptions) {
                return new Http(backend, defaultOptions);
            },
            deps: [MockBackend, BaseRequestOptions]})
    ]);

    it('should have a title', inject([Http], (http) => {
        var instrumentFactory = new InstrumentFactory(http);
        var instrument = instrumentFactory.create({"id" : 7});

        expect(instrument).not.toBeUndefined();
    }));

    it('should also be able to test', () => {
        expect(true).toBe(true);
    });

});

InstrumentFactory.ts:

import {Injectable} from 'angular2/angular2';
import {Http} from 'angular2/http';
import {Instrument} from "../Models/Instrument";

@Injectable()
export class InstrumentFactory {
    private http : Http;

    public constructor(http : Http) {
        this.http = http;
    }

    public create(instrument:any) : Instrument {
        return new Instrument(instrument);
    }

    public all() {
        return this.http.get('http://127.0.0.1:3001/api/Instruments');
    }

    //public find(query : string) : Instrument {
    //    return query;
    //}
}

I am getting the folowing error:

I know that phantomjs is not defined, but that should not really matter to this error.
