NativeScript-单元测试引发错误

Question

我正在使用NativeScript 6+和Angular 8+编写应用程序。我正在尝试使用业力和茉莉花为我的服务编写一些单元测试。我的单元测试抛出错误。

如何正确编写单元测试？我阅读并遵循了此网页上的指示，但仍然无法正常工作：https://docs.nativescript.org/angular/tooling/testing/testing

我遇到的错误不仅发生在其他服务中，也发生在其他服务中。

karma.config.js

// list of files / patterns to load in the browser
files: [
  'src/tests/setup.ts',
  'src/tests/**/*.spec.ts'
],

测试

import {
  nsTestBedAfterEach,
  nsTestBedBeforeEach,
  nsTestBedRender
} from 'nativescript-angular/testing';

import { HttpInterceptorService } from '../app/core/interceptors/http-interceptor-service';

describe('HttpInterceptorService', () => {

  beforeEach(nsTestBedBeforeEach([HttpInterceptorService]));
  afterEach(nsTestBedAfterEach(false));

  it('should be created', () => {
  });

  it('should have its functions defined', () => {
  });

});

错误：

这是我的http拦截器中的代码段：

@Injectable()
export class HttpInterceptorService implements HttpInterceptor {

    constructor(
        private httpLoaderService: HttpLoaderService,
        private authentication: AuthenticationService,
        private ssoAuthentication: SsoAuthenticationService,
        private endpointHelper: EndpointHelperService,
        private router: RouterExtensions
    ) {}

    public intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {

它在名为“核心”的模块中

import { NgModule, NO_ERRORS_SCHEMA } from '@angular/core';
import { NativeScriptCommonModule } from 'nativescript-angular/common';
import { HttpInterceptorService } from './interceptors/http-interceptor-service';
import { HttpLoaderService } from './shared/http-loader.service';
import { NativeScriptHttpClientModule } from 'nativescript-angular/http-client';

@NgModule({
  declarations: [],
  imports: [
    NativeScriptCommonModule,
    NativeScriptHttpClientModule
  ],
  providers: [HttpInterceptorService, HttpLoaderService],
  schemas: [NO_ERRORS_SCHEMA]
})
export class CoreModule { }
