触发效果后，我想在单元测试中测试两个可观察值，以获取此部分代码的100％代码覆盖率。因为a window.location.href被触发，所以我无法正确测试。

export class RouteHelper {
    static redirectToExternalUrl(url: string): any {
        window.location.href = url;
    }
}

影响

@Effect()
handleCreatePaymentSuccess$: Observable<
    {} | routerActions.Go
> = this.actions$.pipe(
    ofType(cartConfigActions.CREATE_PAYMENT_SUCCESS),
    switchMap((action: any) => {
        if (action.payload.redirect) {
            /* istanbul ignore next */
            return Observable.create(
                RouteHelper.redirectToExternalUrl(action.payload.redirect),
            );
        } else {
            return of(
                new routerActions.Go({
                    path: [RouteHelper.paths['validate']],
                }),
            );
        }
    }),
);

测试else条件

it('should dispatch router action Go on success if no redirect url is provided', () => {
    const payload = { redirect: …

从 Angular 7 升级到 Angular 8 后，应用程序路由的 loadChildren 发生了重大变化。当这些问题得到修复并且所有测试都在运行时，我不再获得 100% 的代码覆盖率，因为 loadChildren 不再是“字符串”，而是 LoadChildrenCallBack。

我如何测试这部分代码

设置：

import { NgModule } from '@angular/core';
import { RouterModule, RouterStateSnapshot, Routes } from '@angular/router';
import {
    RouterStateSerializer,
    StoreRouterConnectingModule,
} from '@ngrx/router-store';

import { LanguageGuard } from '@routes/guards/language-guard.service';
import { RouterStateUrl } from 'interfaces';
import { ErrorPageComponent } from 'pages';

/**
 * Class to implements the RouterStateSerializer with a custom serializer
 */
export class CustomSerializer implements RouterStateSerializer<RouterStateUrl> {
    /**
     * Serialize the RouterState with the …
