Angular Material and Jasmine : “ No provider for InjectionToken MdDialogData! ”

Question

I have a component which is meant to be used in an Angular Material MdDialog :

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

  constructor(@Inject(MD_DIALOG_         


        

Answer 1

You can use Angular Optional decorator, I faced this problem before so

if the component is not used as a popup try this snippet

constructor(
  @Optional() public dialogRef: MatDialogRef,
  @Optional() @Inject(MAT_DIALOG_DATA) public data: any
) {}
