Question

@Component({
  ...
})
export class MyComponent {

  constructor(@Inject(MD_DIALOG_         


        

Answer 1

you can inject MAT_DIALOG_DATA / MAT_BOTTOM_SHEET_DATA in jasmine tests without specifying a provider. you must simply ensure that the value being injected is non-null. if it is null, the compiler mistakes the null value for a non-existing provider and you get the provider not found error.
