由于异步区域中的setInterval错误，无法使用highcharts w/jasmine测试组件

我正在尝试为使用highcharts的组件编写ng2 karma/jasmine测试。我正在使用ng2 RC4和当前的jasmine/karma

它有一个错误（如下所示，两个测试都有相同的错误）。我认为异步区域内的setInterval是不可行的，但是highcharts在所有地方都使用setInterval（下面显示的一个示例）&我不知道如何测试这个组件

有人知道我应该如何写这个测试的链接或信息吗

在AsyncTestZoneSpec.eval[作为_failCallback]（/Users//projects/g5 dashboard/dist/vendor/@angular/core/testing/async.js:34:38 Highcharts在其动画中使用setInterval。您可以通过将chart.animation和series.animation设置为false来禁用动画：这家伙显然通过返回承诺来解决问题……甚至不确定这是一个可接受的解决方法：
describe('InteractionBreakdownComponent', () => {
  let fixture: ComponentFixture<any>;
  let component: InteractionBreakdownComponent;

  beforeEach(() => {
    addProviders([
      { provide: Router, useClass: MockRouter },
      { provide: ReportsRouteParamService, useClass: MockParamsService },
      { provide: InteractionBreakdownService, useClass:          MockBreakdownReportService }
    ]);
  });

  beforeEach(async(inject([TestComponentBuilder], (tcb:  TestComponentBuilder) => {
    return tcb.createAsync(InteractionBreakdownComponent)
    .then((fix: ComponentFixture<any>) => {
       fixture = fix;
       component = fix.componentInstance;
    }, err => console.error(err));
  })));

  it('can be created', () => {
    fixture.detectChanges();
    expect(component).toBeTruthy();
  });

  it('sets up params correct', () => {
    fixture.detectChanges();
    expect(component.start_date).toBe('2015-06');

  });
