Angular 4 Karma组件测试因CORS问题失败
Angular 4 Karma组件测试因CORS问题失败
提问于 2017-09-04 20:41:03
当我运行ng test时，当我尝试测试组件时得到这个错误(我在Karma中使用标准设置)：
XMLHttpRequest cannot load ng:///DynamicTestModule/FullModalHeaderComponent.ngfactory.js. Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.
我如何解决这个问题？
代码：
import { async, ComponentFixture, TestBed } from '@angular/core/testing';
import { FullModalHeaderComponent } from './full-modal-header.component';
describe('FullModalHeaderComponent', () => {
let component: FullModalHeaderComponent;
let fixture: ComponentFixture<FullModalHeaderComponent>;
beforeEach(async(() => {
TestBed.configureTestingModule({
declarations: [FullModalHeaderComponent]
})
.compileComponents();
}));
beforeEach(() => {
fixture = TestBed.createComponent(FullModalHeaderComponent);
fixture.detectChanges();
});
it('should be created', () => {
expect(component).toBeTruthy();
});
});和
import { Component, Input } from '@angular/core';
import { ProcessingCenter, Publication } from '../../publications/model';
@Component({
selector: 'gom-full-modal-header',
templateUrl: './full-modal-header.component.html'
})
export class FullModalHeaderComponent {
@Input('processingCenter') processingCenter: ProcessingCenter;
@Input('publication') publication: Publication;
@Input('title') title: string;
}此外，当我使用ng test --sourcemaps=false运行测试时，问题也消失了。
