Unit tests: Can't bind to 'ngModel' since it isn't a known property of 'ui-switch'

[Lewis]

I've managed to use the module successfully, but now i'm trying to make it pass our unit tests, and it fails with the error Can't bind to 'ngModel' since it isn't a known property of 'ui-switch'.

Here is my test component

import { UiSwitchModule } from 'angular2-ui-switch';

describe('HubPreviewComponent', () => {
  let component: HubPreviewComponent;
  let fixture: ComponentFixture<HubPreviewComponent>;

  beforeEach(async(() => {
    TestBed.configureTestingModule({
      declarations: [HubPreviewComponent, OfferPreviewComponent],
      imports: [ReactiveFormsModule, UiSwitchModule],
      providers: [ ... ]
    }).compileComponents();
  }));

I've also tried using import { UiSwitchModule } from '../../../node_modules/angular2-ui-switch/src'; as a previous post suggested.
