javascript - 异步需要 AsyncTestZoneSpec

问题描述

Angular v4到目前为止，该应用程序是在每个版本的基础上构建并逐渐更新的。目前我们正在进行中Angular v7，最终 CEO 同意编写单元测试，而以前并非如此。

我刚刚创建了一个简单的规范来开始测试并开始在整个项目中实施它，但是由于以下错误而卡住了两天：

async() 测试助手需要 AsyncTestZoneSpec，但无法找到。请确保您的环境包含 zone.js/dist/async->test.js

在搜索上述错误时，我找到了一些答案，但这些答案与 Angular 有关，Wallaybyjs但又是特定于 Angular 的。

我试图通过该项目的全新安装来重现该问题，angular但实际上并不能。这可能是在Angular 7.

以下是test.ts文件：

// This file is required by karma.conf.js and loads recursively all the .spec and framework files

import 'zone.js/dist/long-stack-trace-zone';
import 'zone.js/dist/proxy.js';
import 'zone.js/dist/sync-test';
import 'zone.js/dist/jasmine-patch';
import 'zone.js/dist/async-test';
import 'zone.js/dist/fake-async-test';
import { getTestBed } from '@angular/core/testing';
import {
  BrowserDynamicTestingModule,
  platformBrowserDynamicTesting
} from '@angular/platform-browser-dynamic/testing';

// Unfortunately there's no typing for the `__karma__` variable. Just declare it as any.
declare const __karma__: any;
declare const require: any;

// Prevent Karma from running prematurely.
__karma__.loaded = function () {};

// First, initialize the Angular testing environment.
getTestBed().initTestEnvironment(
  BrowserDynamicTestingModule,
  platformBrowserDynamicTesting()
);
// Then we find all the tests.
const context = require.context('./', true, /\.spec\.ts$/);
// And load the modules.
context.keys().map(context);
// Finally, start Karma to run the tests.
__karma__.start();

和Package.json：

import { InsuranceComponent } from './insurance.component';

import { InsuranceRoutingModule } from '../insurance-routing/insurance-routing.module';
import { InsuranceSearchItemComponent } from '../insurance-search-item/insurance-search-item.component';
// tslint:disable-next-line:max-line-length
import { InsuranceSearchItemDetailsComponent } from '../insurance-search-item/insurance-search-item-details/insurance-search-item-details.component';

describe('Insurance Component', () => {
    let component: InsuranceComponent;
    let fixture: ComponentFixture<InsuranceComponent>;

    beforeEach(async(() => {
        TestBed.configureTestingModule({
            imports: [
                CartModule,
                SharedModule,
                CommonModule,
                MbscModule,
                FormsModule,
                NgbModule,
                PipeModule,
                InfiniteScrollModule,
                InsuranceRoutingModule
            ],
            declarations: [InsuranceComponent, InsuranceSearchItemComponent, InsuranceSearchItemDetailsComponent]
        }).compileComponents();

        fixture = TestBed.createComponent(InsuranceComponent);
        component = fixture.componentInstance;
        fixture.detectChanges();
    }));

    it('should create', () => {
        expect(component).toBeTruthy();
    });
});

任何帮助将不胜感激。谢谢
