I just upgraded to Angular RC 5 and now all component that uses 'ROUTER_DIRECTIVES' fails with 'Can't resolve all parameters for Router: (?, ?, ?, ?, ?, ?, ?)' when I try to unit test the component.
import { inject, addProviders } from '@angular/core/testing';
import { ComponentFixture, TestComponentBuilder } from '@angular/core/testing';
import { Component } from '@angular/core';
import { ROUTER_DIRECTIVES, Router } from '@angular/router';
import { HomeComponent } from './home.component';
import { UserService } from '../_services/user.service';
describe('Component: Home', () => {
beforeEach(() => {
addProviders([HomeComponent, UserService, ROUTER_DIRECTIVES, Router]);
});
it('should inject the component', inject([HomeComponent, UserService, ROUTER_DIRECTIVES, Router],
(component: HomeComponent) => {
expect(component).toBeTruthy();
// expect(component.currentUser.firstname).toEqual('Jan');
}));
The full error log:
Chrome 52.0.2743 (Windows 10 0.0.0)
Error: Can't resolve all parameters for Router: (?, ?, ?, ?, ?, ?, ?).

Any ideas how to unit test components with routing?
Was finally able to fix it, and it was as simple as this:
beforeEach(() => addProviders([
{
provide: Router,
useClass: class { navigate = jasmine.createSpy("navigate"); }
}]));
