问题描述
I have a component which is meant to be used in an Angular Material MdDialog :
@Component({
...
})
export class MyComponent {
constructor(@Inject(MAT_DIALOG_DATA) public data: any, public dialogRef:
MdDialogRef<MyComponent>) {
...
}
}
I am trying to Unit Test it with Jasmine :
describe('MyComponent', () => {
let component: MyComponent;
let fixture: ComponentFixture<MyComponent>;
beforeEach(async(() => {
TestBed.configureTestingModule({
imports: [
SharedTestingModule,
],
declarations: [
MyComponent,
],
})
.compileComponents();
}));
...
});
Unfortunately, I am getting the following error :
Error: No provider for InjectionToken MdDialogData!
SharedTestingModule imports and exports my custom Angular Material module, which itself imports and exports MdDialogModule.
How can I get rid of this error?
Thank you very much!
Angular 4.2.4
Angular Material 2.0.0-beta.7
Jasmine 2.5.3
解决方案
I added this :
providers: [
{ provide: MAT_DIALOG_DATA, useValue: {} },
{ provide: MdDialogRef, useValue: {} }
]
And it works :)
Thanks for your help @methgaard!
