问题描述
我有一个用于 Angular Material MdDialog 的组件:
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>) {
...
}
}
我正在尝试使用 Jasmine 对其进行单元测试:
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();
}));
...
});
不幸的是,我收到以下错误:
Unfortunately, I am getting the following error :
错误:InjectionToken MdDialogData 没有提供程序!
SharedTestingModule 导入和导出我的自定义 Angular Material 模块,该模块本身导入和导出 MdDialogModule.
SharedTestingModule imports and exports my custom Angular Material module, which itself imports and exports MdDialogModule.
我怎样才能摆脱这个错误?
How can I get rid of this error?
非常感谢!
Angular 4.2.4
Angular Material 2.0.0-beta.7
Jasmine 2.5.3
推荐答案
我添加了这个:
providers: [
{ provide: MAT_DIALOG_DATA, useValue: {} },
{ provide: MdDialogRef, useValue: {} }
]
它有效:)
