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和当前的茉莉/业力。
它有一个错误（如下所示，两个测试都有相同的错误）。我看来异步区域中的setInterval是禁止的，但是highcharts在整个地方都使用了setInterval（如下所示，一个例子）＆amp;我不确定如何测试这个组件。
有没有人有关于我应该如何编写此测试的链接或信息？

我正在测试组件，如：
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');
expect(component.end_date).toBe('2015-09');
});
