This is demonstrated below: var foo: any; var bar = <string> foo; // bar is now of type

Angular, unit testing a component that creates a service via an interface

由 喜你入骨 提交于 2019-12-13 04:36:11
问题 Given this component that creates a service locally @Component({ <removed for clarity> providers: [ { provide: 'IMyService', useClass: MyService }, ] }) export class MyComponent implements OnInit, OnDestroy, AfterViewInit { constructor(private data: IMyService){} } I've been trying to supply the service in the unit test, something like this beforeEach(async(() => { TestBed.configureTestingModule({ declarations: [MyComponent], providers: [ { provide: 'IMyService', useClass: MockMyService }, ]

Angular 6 Unit Test ngOnInit with a setTimeOut not working

由 蹲街弑〆低调 提交于 2019-12-12 10:21:27
问题 I have a component with a setTimeOut function inside a ngOnInit function. To write unit test cases for that I'm using tick and fakeAsync to fast forward the setTimeOut. But, it's not getting executed which in turn is not calling other function closeAlert(). Component code: export class BannerComponent implements OnInit { @Input()errorData: any; @Input()callback: any; @Input()autoHide: boolean; constructor() { } ngOnInit() { if (this.autoHide) { setTimeout (() => { this.closeAlert(); }, 500);

Angular CLI create .spec files for already existing components

由 假如想象 提交于 2019-11-30 06:50:34
问题 There is an option in .angular-cli.json to disable the automatic creating of *.spec files e.g. for components, see json schema. This is a really nice feature because personally (this is just my opinion) testing the components might not be the thing that really worth it in a fast growing project. However sometimes I would like to have an option to generate / recreate the corresponding *.spec file for an already existing component / service / pipe / whatsoever. Is that possible using some
