Hello, I'm trying to write unit tests for a component and I keep getting this error Error: MatDatepicker: No provider found for DateAdapter. You must import one of the following modules at your application root: MatNativeDateModule, MatMomentDateModule, or provide a custom implementation.

My testbed :

describe('DateSelectComponent', () => {
  // Define Testbed
  let spectator: Spectator<DateSelectComponent>
  const createComponent = createComponentFactory({
    component: DateSelectComponent,
    imports: [
      MatFormFieldModule,
      MatDatepickerModule,
      CommonModule,
      MatMomentDateModule,
      MatInputModule,
      TranslateModule.forRoot({
        defaultLanguage: "ar",
        loader: {
          provide: TranslateLoader,
          useFactory: HttpLoaderFactory,
          deps: [HttpClient]
        }
      }),
    ],
    providers: [
      HttpClient,
      {
        provide: MAT_DATE_FORMATS,
        useValue: MY_FORMATS
      }
    ]
  });

  beforeEach(() => spectator = createComponent())

  // Tests
  it('Should load', () => {
    expect(spectator.component).toBeTruthy()
  })
})
