Невозможно протестировать Angular http сервис с использованием Jasmine и Karma

Я пытаюсь проверить перехватчик http, используя Жасмин и Карму. Я получаю ошибку ниже: 

 × should return same response to a request

Error: In this configuration Angular requires Zone.js

Мой код ниже: 

// Http testing module and mocking controller
import { HttpClientTestingModule, HttpTestingController } from '@angular/common/http/testing';

// Other imports
import { TestBed } from '@angular/core/testing';
import { HttpClient } from '@angular/common/http';

describe('HttpClient testing', () => {
    let httpClient: HttpClient;
    let httpTestingController: HttpTestingController;

    beforeEach(() => {
        TestBed.configureTestingModule({
            imports: [ HttpClientTestingModule ]
        });

        // Inject the http service and test controller for each test
        httpClient = TestBed.inject(HttpClient);
        httpTestingController = TestBed.inject(HttpTestingController);
    });
    /// Tests begin ///
    it('Just a simple test', () => {
        expect(1).toEqual(1)
  // Finally, assert that there are no outstanding requests.
  httpTestingController.verify();
});
});

Если я добавлю импорт 'zone.js / dist / zone', я получу ошибку ниже:

Я не уверен, что происходит. Не входит ли зона js в Angular CLI. Я запускаю тесты, используя команду ng test. Любая помощь очень ценится. Оскорбительные операторы, кажется, TestBed.inject в коде. Если я удаляю их, я не получаю никаких исключений.
