我似乎无法测试在Angular 2中使用Date管道的组件(通过PhantomJS使用Karma).当我尝试时,我得到ORIGINAL EXCEPTION：ReferenceError：找不到变量：Intl
这是我的整个spec文件：
import { provide,PLATFORM_PIPES } from '@angular/core';
import { DatePipe } from '@angular/common';
import { addProviders,async,inject } from '@angular/core/testing';
import { Post,PostComponent,PostHtmlComponent } from './';
import { usingComponentFixture } from '../../test-helpers';
describe('Component: Post',() => {
beforeEach(() => {
provide(PLATFORM_PIPES,{useValue: DatePipe,multi: true });
addProviders([PostComponent,PostHtmlComponent,]);
});
it('should render an h1 tag with text matching the post title',usingComponentFixture(PostComponent,fixture => {
let component = <PostComponent>fixture.componentInstance;
let element = fixture.nativeElement;
component.post = <Post>{ title: 'Hello',publishedOn: new Date('8/5/2016') };
fixture.detectChanges();
expect(element.querySelector('.blog-post-header h1').innerText).toBe('Hello');
})
);
});
这是组件模板：
<div class="col-lg-8 col-md-7 col-sm-6">
<h1>{{post.title}}</h1>
<p class="lead">{{post.publishedOn | date:'fullDate'}}</p>
</div>
我能够解决这个问题.这就是我必须做的事情：
原文链接：https://www.f2er.com/angularjs/141425.html> npm install karma-intl-shim –save-dev
>将’intl-shim’添加到karma.conf.js中的frameworks集合中
>将以下内容添加到karma-test-shim.js(这在karma.conf.js的文件集合中引用)
require('karma-intl-shim');
require('./en-us.js'); // copied from https://github.com/andyearnshaw/Intl.js/blob/master/locale-data/json/en-US.json
Intl.__addLocaleData(enUsLocaleData);
