Jasmine 3角度5.2测试中的错误

运行后出现一些错误 ng test ,我在对所有软件包进行升级后发现,以下是版本:

{
"@angular/animations": "^5.2.0",
"@angular/common": "^5.2.0",
"@angular/compiler": "^5.2.0",
"@angular/core": "^5.2.0",
"@angular/forms": "^5.2.0",
"@angular/http": "^5.2.0",
 ...
 "zone.js": "^0.8.19"
 }

和devDependencies

"jasmine-core": "~3.1.0",
"jasmine-spec-reporter": "~4.2.1",
"karma": "~2.0.0",
"karma-chrome-launcher": "~2.2.0"

我遇到了以下错误:

"message": "An error was thrown in afterAll\n[object ErrorEvent]", "str": "An error was thrown in afterAll\n[object ErrorEvent]"

我的所有测试都非常简单,如:

import { async, TestBed  } from '@angular/core/testing';
import { UserInmailComponent } from './user-inmail.component';

describe('Component: UserInmail', () => {
it('should create an instance', () => {
  const component = new UserInmailComponent();
  expect(component).toBeTruthy();
});
});

我不认为是我的测试文件导致了这个问题。
