【问题描述】:
我目前正在使用 angular-cli 处理 angular2 项目。从明天开始,我从 ng test 命令得到一个新错误,下面的跟踪。每次我运行 ng test 命令时都会触发此错误。我在 spec.ts 中识别出引发错误的代码:
const fakeRouter = jasmine.createSpyObj('Router', ['navigate']);
beforeEach(() => TestBed.configureTestingModule({
imports: [AppModule, RouterTestingModule],
providers: [{ provide: Router, useValue: fakeRouter }]
}));
当我删除提供商路由器时,错误消失了。 但是,我所有的测试都成功通过了。
我的 angular-cli 版本:
angular-cli: 1.0.0-beta.32.3 节点:6.7.0 操作系统:win32 x64
错误:
ERROR: 'Unhandled Promise rejection:', 'Cannot set property 'afterPreactivation' of undefined', '; Zone:', 'ProxyZone', '; Task:', 'Promise.then', '; Value:', TypeError{}, 'TypeError: Cannot set property 'afterPreactivation' of undefined
