NativeScript-运行单元测试时的ZoneAwareError

Question

我正在使用NativeScript 6+和Angular 8+编写应用程序。 我正在尝试编写一些单元测试并使它们启动并运行。 我已阅读有关单元测试的文档：https://docs.nativescript.org/tooling/testing/testing 我运行了 tns test init 和 tns test android 来准备测试。 我按照那里的指示来设置测试和使用TestBed。我的测试无法正常工作并引发错误。 这是我的存储库：https://github.com/aubrey-fowler/NativeScriptUnitTests

样本测试：

using System;
using Moq;
using MugenMvvmToolkit;
using MugenMvvmToolkit.Infrastructure;
using MugenMvvmToolkit.Interfaces;
using MugenMvvmToolkit.Interfaces.Presenters;
using MugenMvvmToolkit.Models;
using Xunit;

namespace Mobile.Pull.Agro.Tests
{
    public class UnitTest1 : UnitTestBase
    {
        public UnitTest1()
        {
            _viewModelPresenterMock = new Mock<IViewModelPresenter>();
            _serializer = new Serializer(AppDomain.CurrentDomain.GetAssemblies());
            var container = new AutofacContainer();
            container.BindToConstant(_viewModelPresenterMock.Object);
            Initialize(container, new DefaultUnitTestModule());
            ApplicationSettings.CommandExecutionMode = CommandExecutionMode.None;
        }

        private Mock<IViewModelPresenter> _viewModelPresenterMock;
        private ISerializer _serializer;

        [Fact]
        public void Test1()
        {
           Assert.True(true);
        }
    }
}

运行测试时，出现此错误：

import { ItemsComponent } from '../app/item/items.component';
import { ItemService } from '../app/item/item.service';

import { nsTestBedAfterEach, nsTestBedBeforeEach, nsTestBedRender } from 'nativescript-angular/testing';

describe('ItemsComponent Test', () => {

    beforeEach(nsTestBedBeforeEach([ItemService, ItemsComponent]));
    afterEach(nsTestBedAfterEach(false));

    it('should be defined', () => {

        nsTestBedRender(ItemsComponent).then((fixture) => {
            fixture.detectChanges();
            const component = fixture.componentInstance;
            expect(component).toBeTruthy();
        });

    });

});
