Angular 2 - 错误：令牌FirebaseAppName没有提供者 [英] Angular 2 - Error: No provider for Token FirebaseAppName

问题描述

 错误：没有Token的提供者FirebaseAppName！ 
  

这里是我的规格：

<$ p $从'@ angular / core / testing'导入{TestBed，inject};
从'./api.service'中导入{ApiService};
从'@ angular / http'导入{HttpModule};
从'angularfire2'导入{FIREBASE_PROVIDERS，defaultFirebase，AngularFire}; $（）= $ {
} firebaseConfig = {
apiKey：foo，
authDomain：bar，
databaseURL：baz，
storageBucket：foo，
messagingSenderId：bar
}

TestBed.configureTestingModule（{
// providers：[ApiService，defaultFirebase（firebaseConfig）]，
providers：[ApiService，FIREBASE_PROVIDERS，defaultFirebase（firebaseConfig）]，
imports：[




$（应该...），注入（[ApiService]，（service：ApiService） => {
expect（service）.toBeTruthy（）;
}））;
}）;

预先感谢您。

版本：

 @ angular / core：^ 2.4.0，
jasmine-core： 2.5.2，
firebase：^ 3.7.0，
  

解决方案

尝试配置模块而不是提供者

TestBed.configureTestingModule（{$ b $ providers：[ApiService]
imports：[
HttpModule，$（



$ pre
AngularFireModule.initializeApp（firebaseConfig）
]
}）;

My app is running fine, but I cannot get my tests to pass with Firebase.

Error: No provider for Token FirebaseAppName!

Here is me spec:

import { TestBed, inject } from '@angular/core/testing';
import { ApiService } from './api.service';
import { HttpModule } from '@angular/http';
import {FIREBASE_PROVIDERS, defaultFirebase, AngularFire} from 'angularfire2';

describe('ApiService', () => {
  beforeEach(() => {
    const firebaseConfig = {
      apiKey: "foo",
      authDomain: "bar",
      databaseURL: "baz",
      storageBucket: "foo",
      messagingSenderId: "bar"
    }

    TestBed.configureTestingModule({
      // providers: [ApiService, defaultFirebase(firebaseConfig)],
     providers: [ApiService, FIREBASE_PROVIDERS, defaultFirebase(firebaseConfig)],
     imports: [
       HttpModule
     ]
   });
 });

 it('should ...', inject([ApiService], (service: ApiService) => {
   expect(service).toBeTruthy();
 }));
});

Thanks in advance.

Versions:

"@angular/core": "^2.4.0",
"jasmine-core": "~2.5.2",
"firebase": "^3.7.0",

解决方案

Try to configure module instead of provider

TestBed.configureTestingModule({
  providers: [ApiService]
  imports: [
    HttpModule,
    AngularFireModule.initializeApp(firebaseConfig)
  ]
});
