testing AppComponent : No provider for TransitionController!

Is it possible to test the functions in the AppComponent?

TransitionController is private in ionic, so I can't import that.

app.component.spec.ts

describe('Pages: AppComponent', () => {

    beforeEach(async(() => TestUtils.beforeEachCompiler([AppComponent], [
        { provide: Platform, useClass: PlatformMock },
        { provide: Config, useClass: ConfigMock },
        { provide: AppService, useClass: AppService },
    ]).then(compiled => {
        fixture = compiled.fixture;
        instance = compiled.instance;
    })));

    it('should create the app component', async(() => {
        expect(instance).toBeTruthy();
    }));
});

test.ts

export class TestUtils {

  public static beforeEachCompiler(components: Array<any>, providers: Array<any>): Promise<{ fixture: any, instance: any }> {
    return TestUtils.configureIonicTestingModule(components, providers)
      .compileComponents().then(() => {
        let fixture: any = TestBed.createComponent(components[0]);
        return {
          fixture: fixture,
          instance: fixture.debugElement.componentInstance,
        };
      });
  }

  public static configureIonicTestingModule(components: Array<any>, providers: Array<any>): typeof TestBed {
    return TestBed.configureTestingModule({
      declarations: [
        ...components,
      ],
      providers: [
        ...providers,
        App, Form, Keyboard, DomController, MenuController, NavController, GestureController
      ],
      imports: [
        IonicModule //.forRoot(AppComponent)
      ],
    });
  }

  public static eventFire(el: any, etype: string): void {
    if (el.fireEvent) {
      el.fireEvent('on' + etype);
    } else {
      let evObj: any = document.createEvent('Events');
      evObj.initEvent(etype, true, false);
      el.dispatchEvent(evObj);
    }
  }
}
