问题 How to unit testing an $destroy event of a Directive in angularjs? I have the code in my directive: scope.$on('$destroy', function () { //clean something }); My test code: it('on destroy',function(){ scope.$destroy(); scope.$digest(); //expect everything done? }); Any suggestion! 回答1: You can select the DOM from the template of your directive and get the scope of it, then run $destroy().

问题 I'm doing unit testing with Jasmine/Karma against an Angular service. I'd like to confirm that my service properly filters items. For example, if I have a service to get people over a certain age, it should return people over the minimum age (positive case) should NOT return people under a the minimum age (negative case) It's #2 that I'm struggling to test. The service: getPeople(minAge: number): Observable<string> { const source = Observable.from([ { name: 'Joe', age: 30 }, { name: 'Frank',

问题 I'm trying to make an automated test for my webpage and I'm using Jasmine in tandem with selenium. When testing on chrome (using chromedriver) I get, unpredictably, the error below. It happens frequently enough that when I run a test suite it hardly ever finishes. Ive found evidence of this bug but cant find a solid answer: https://bugs.chromium.org/p/chromedriver/issues/detail?id=732 (granted this was for chromium and I'm using chrome) WebDriverError: no such session (Driver info:

I've a component ArticlesComponent which uses ArticlesService to fetch all those articles. Today I want to test ArticlesComponent only. Here is the code. articles.component.ts import { Component, OnInit } from '@angular/core'; import { ArticleService } from '../article.service'; ... @Component({ ... })

问题 I'm trying to write a test that checks for the existence of a route using Jasmine for Angular application: import { routes } from './app-routing.module'; import { UsersComponent } from './users/users.component'; describe('routes', () => { it('should contain route for /users', () => { const expectedRoute = { path: 'users', component: UsersComponent }; expect(routes).toContain(expectedRoute); }); }); but the test fails (probably because of object equality in Javascript How object equality

问题 I have checked a lot of articles and answers but I don't seem to find the right way to mock HTTP Requests for my methods. I want to test my frontend application independently from the backend . Here is the type of methods I have: private getProfile() { this.http .get('go/profile/get', {withCredentials: true}) .subscribe((profile: Profile) => { this.user.profile = profile; this.updateLineMsgs(); }); } Any suggestions ? 回答1: Usually i mock my Http requests with HttpClientTestingModule : import

问题 When I type "npm run test" in the command line, npm goes to package.json, to the "scripts" section and tries to match "test" there. So far so good. Now, the line behind "test" is the following: "JASMINE_CONFIG_PATH=./spec/support/jasmine.json jasmine-run" but the first part (everything except "jasmine-run") can be removed witout problems.
