Jasmine: Mocking API requests in an Angular service spec

Copy# Capitalized expressions are intended to be replaced with YOUR values

describe 'SERVICE', ->

  beforeEach ->
    module 'MODULE'

    module ($urlRouterProvider) ->
      # Prevent uiRouter's initialization, i.e. do not sync the current URL
      # with its routes
      $urlRouterProvider.deferIntercept()

    inject (_$httpBackend_, _SERVICE_) =>
      @$httpBackend = _$httpBackend_
      @SERVICE = _SERVICE_

  afterEach ->
    @$httpBackend.verifyNoOutstandingExpectation()
    @$httpBackend.verifyNoOutstandingRequest()

  describe 'FUNCTION()', ->
    it 'does something', ->
      # Maybe some code here
      
      # Call function under test (triggers API request, which will be intercepted)
      @SERVICE.FUNCTION()
      
      # ... do something before request is answered
      
      # Set up request expectation
      @$httpBackend.expectGET('/api/something').respond
        nested:
          example: 'json'
      
      # Run all queued requests
      @$httpBackend.flush()
      
      # Have a Jasmine expectation
      expect(something).toHaveHappened()
