Question

我是Karma / Jasmine单元测试的新手，我正在尝试为我的身份验证组件编写一些测试，其中注入了一个AuthService。我还有另一个身份验证服务，用于注入通用AuthService的Microsoft（Azure）身份验证。为了建立我的规范，我有：

describe('AuthAdminComponent', function () {
  let de: DebugElement;
  let comp: AuthAdminComponent;
  let fixture: ComponentFixture<AuthAdminComponent>;
  let authService: AuthService;

  let authServiceStub: {
    // Fill in later
  }

    beforeEach(async(() => {
    TestBed.configureTestingModule({
      declarations: [ AuthAdminComponent ], // declare the test component
      providers: [
        {provide: AuthService, useValue: authServiceStub},
      ]
    })
    .compileComponents(); // compile template and css
  }));

  beforeEach(() => {
    fixture = TestBed.createComponent(AuthAdminComponent);
    comp = fixture.componentInstance;
    authService = TestBed.get(authService) // Get the needed service
  });

})

目前没有任何测试，因为我想确保一切都正确设置。但是，当我运行npm test时，我会收到：

404: /base/node_modules/ng2-adal/core.js
Chrome 59.0.3071 (Windows 10 0.0.0) ERROR

{

[1]         "source": "Promise.then",

[1]         "runCount": 0
[1]       }
[1]     },

[1]       "cancelFn": null,
[1]       "runCount": 0
[1]     }
[1]   }

我不太明白我哪里出错了。显然，它没有找到.js文件，但该.js文件确实存在于该位置，并且在我正常运行Angular应用程序时工作正常。所以我只是假设我错误地设置了测试？任何帮助，将不胜感激。我一直在尝试按照Angular文档进行测试。如果这会有所帮助，那么我的AuthService的开头就是这样的：

import {Injectable} from '@angular/core';
import { Headers, Http, Response } from '@angular/http';
import 'rxjs/Rx';
import { Observable } from 'rxjs/Observable';
import { AdalService } from 'ng2-adal/core';

@Injectable()
export class AuthService {

    public authType: string = null;
    public connection: string = null;
    public accessToken: string = null;
    public refreshToken: string = null;

    constructor(private adalService: AdalService, private http: Http) {}

通过编辑karma.conf.js文件并添加到文件来解决这个问题：[]

{ pattern: 'node_modules/ng2-adal/**/*.js', included: false, watched: false },
{ pattern: 'node_modules/ng2-adal/**/*.js.map', included: false, watched: false },
{ pattern: 'node_modules/adal-angular/**/*.js', included: false, watched: false },
{ pattern: 'node_modules/adal-angular/**/*.js.map', included: false, watched: false },
