効果がトリガーされたら、単体テストで両方のオブザーバブルをテストして、コードのこの部分の 100% のコード カバレッジを取得したいと考えています。awindow.location.hrefがトリガーされるため、正しくテストできません。

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

効果

@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']],
                }),
            );
        }
    }),
);

else 条件の動作をテストする

it('should dispatch router action Go on success if no redirect url is provided', () => {
    const payload = { redirect: null };
    const action = new fromCartConfig.CreatePaymentSuccess(payload);
    const completion = new routeractions.Go({
        path: [RouteHelper.paths['validate']],
    });

    actions$.stream = cold('-a', { a: action });
    const expected = cold('-c', { c: completion });

    expect(effects.handleCreatePaymentSuccess$).toBeObservable(expected);
});

if 条件でテストが機能しない

it('should redirect to url that is returned from api', () => {
    const payload = { redirect: 'http://www.stackoverflow.com' };
    spyOn(RouteHelper, 'redirectToExternalUrl').withArgs(payload.redirect);

    const action = new fromCartConfig.CreatePaymentSuccess(payload);
    const completion = Observable.create(RouteHelper.redirectToExternalUrl);

    actions$.stream = cold('-a', { a: action });
    const expected = cold('-c', { c: completion });

    expect(effects.handleCreatePaymentSuccess$).toBeObservable(expected);
});

誰かがIf条件をテストする方法を説明できますか?
