抛出角6更新规范[对象ErrorEvent]
抛出角6更新规范[对象ErrorEvent]
提问于 2018-05-23 14:56:38
我正在升级一个从版本4到版本6的角形应用程序。所有的东西都用ng serve正确地运行。现在的问题是，我们的一些规范文件在[object ErrorEvent] thrown中失败了。我以前见过这种情况，通常可以使用--sourceMap=false标志运行测试来查看更详细的报告，但现在我仍然会看到这个不明确的错误。我已经检查过没有一个组件有任何未定义的输入。经过一些研究，我发现一些人对茉莉花核心3.0.0有问题，并收到了这个错误，直到他们回到2.99.0，但这对我也没有任何帮助。
最奇怪的是，我可以xdescribe的规范(或所有的规格)，失败的这个错误，然后不同的失败，以前没有失败。
这是package.json

}下面是目前正在失败的规范之一(其中大多数比这复杂得多，但这使我认为这不是测试本身的问题)：
import { HttpClientModule } from '@angular/common/http';
import { MaterialModule } from '../../modules/material.module';
import { async, ComponentFixture, TestBed } from '@angular/core/testing';
import { NumberPerPageComponent } from './number-per-page.component';
import { NoopAnimationsModule } from '@angular/platform-browser/animations';
describe('NumberPerPageComponent', () => {
let component: NumberPerPageComponent;
let fixture: ComponentFixture<NumberPerPageComponent>;
beforeEach(async(() => {
TestBed.configureTestingModule({
declarations: [ NumberPerPageComponent ],
imports: [
HttpClientModule,
MaterialModule,
NoopAnimationsModule
]
})
.compileComponents();
}));
beforeEach(() => {
fixture = TestBed.createComponent(NumberPerPageComponent);
component = fixture.componentInstance;
fixture.detectChanges();
});
it('should be created', () => {
expect(component).toBeTruthy();
});
});下面是组件本身：
import { Component } from '@angular/core';
@Component({
selector: 'app-number-per-page',
templateUrl: './number-per-page.component.html',
styleUrls: ['./number-per-page.component.scss']
})
export class NumberPerPageComponent {
resultNumber = 10;
constructor() { }

我遇到的问题是将HttpClientModule导入到我的规范中，而不是HttpClientTestingModule。
这些测试试图发出api调用，但是当它们从后端接收401个响应时失败了。

这种错误通常直接抛到浏览器中:您可以在控制台中看到此消息，但真正的错误是浏览器的dev工具。你能不能尽快检查一下，看看你的错误是否发生了？
否则，它将告诉您哪个测试失败:尝试异步运行此测试，或者使用回调中的参数：
it('XXX', done => {
// do your things then
done();
