angular - service (which have dependencies) unit tests with angular2 -

i'm starting angular2 unit tests , running problems. have service accepts parameters applicationref , componentresolver service uses componentresolver load component dynamically. question how can pass in unit tests service above parameters?

does example you:

import {component, provide} '@angular/core'; import {componentfactory} '@angular/core/src/linker/component_factory'; import {componentresolver, reflectorcomponentresolver} '@angular/core/src/linker/component_resolver'; import {reflectioninfo, reflector} '@angular/core/src/reflection/reflection'; import {aftereach, beforeeach, beforeeachproviders, ddescribe, describe, expect, iit, inject, it, xdescribe, xit} '@angular/core/testing/testing_internal'; import {asynctestcompleter} '@angular/core/testing/testing_internal'; import {console} '../../src/console';  class dummyconsole implements console {   log(message: string) {}   warn(message: string) {} }  export function main() {   describe('compiler', () => {     var somecompfactory: /** todo #9100 */;     var compiler: componentresolver;      beforeeach(() => {       somecompfactory = new componentfactory(null, null, null);       reflector.registertype(somecomponent, new reflectioninfo([somecompfactory]));       compiler = new reflectorcomponentresolver(new dummyconsole());     });      it('should read template annotation',        inject([asynctestcompleter], (async: asynctestcompleter) => {          compiler.resolvecomponent(somecomponent).then((compfactory: componentfactory<any>) => {            expect(compfactory).tobe(somecompfactory);            async.done();            return null;          });        }));      it('should throw when given string',        inject([asynctestcompleter], (async: asynctestcompleter) => {          compiler.resolvecomponent('somestring').catch((e) => {            expect(e.message).tocontain('cannot resolve component using \'somestring\'.')                async.done();          });        }));   }); }  class somecomponent {}
