Angular 2单元测试：无法读取未定义的属性“root”

<a [routerLink]="['/my-profile']" routerLinkActive="active">
    <i class="icon-user"></i>{{ 'MY_PROFILE' | translate }}
</a>

错误是因为routerLink和routerLinkActive指令.

单元测试文件.

TestBed.configureTestingModule({
    imports: [
        MultilingualModule,CommonModule,RouterTestingModule.withRoutes([
            { path: 'my-profile',component: MockComponent },{ path: 'change-password',])
    ],schemas: [ NO_ERRORS_SCHEMA ],declarations: [TopNavigationBarComponent,TestComponent,MockComponent],providers: [
        { provide: LoginService,useValue: MockLoginService },{ provide: Router,useClass: RouterStub }
    ]
});
