karma-jasmine

问题 None of my components were passing unit tests, so I made a new one in the project to try and diagnose. import { Component, OnInit } from '@angular/core'; @Component({ selector: 'app-thing', templateUrl: './thing.component.html', styleUrls: ['./thing.component.scss'] }) export class ThingComponent implements OnInit { constructor() { } ngOnInit() { } } And a thing.component.spec.ts file as follows describe('ThingComponent', () => { let component: ThingComponent; let fixture: ComponentFixture

I would like to mock an error in my service, then check that it catches an error observable. I have another service that creates and throws the error observable. The rest of my services just catch it when encountering an error. I am honestly very confused on how to implement this. Here is a simple verison of

问题 I have a slide-show component that has an Input array of slide objects and shows each one as long as it's been defined in slide.time of itself. also there are two buttons that clicking them has to slide to the next item and reset the timer. in order to make this work, I'm using Observables like this: /** * a "SUBJECT" for pausing(restarting) the slider's auto-slide on user's click on left and right arrows * @type {Subject} */ private pauser = new Subject(); /** * the main observable for timer

问题 I'm trying to test a component that has an @ViewChild annotation. One of the functions that I'm trying to test calls the @ViewChild 's element for focus. However, when I try to log out the @ViewChild variable, it is always undefined . I thought componentFixture.detectChanges() would initiate the ElementRef , but it doesn't seem to.

问题 I am using Angular 1.2.6 . I am trying to use bower to install angular-animate and ngAnimate-animate.css.
