How to mock AngularFire 2 service in unit test?

Question

I\'m trying to set up unit tests for a sample Angular 2 app using AngularFire 2 auth, the component is fairly simple:

import { Component } from \'@angular/core\'         


        

Answer 1

hope it is not off the topic, but the easiest solution I have found how to mock the FirebaseDatabase.

var object = function() {
      var obj = { valueChanges() {
            return of({data:'data'});     
        }
      }
      return obj;
    }

providers: [..., { provide : AngularFireDatabase,
        useValue: {object : object }} ]

instead of data:'data' you can mock whatever data you need. The functions can be modified as you wish.
