Unknown release of injection prototyping in angular test

Question

This is my module declaration:

(angular.module 'services.date', [])

.service '$date', () ->
  # stuff
  this

This is my injection code:

describe 'Service: dateService', () ->
  dateService = null
  beforeEach module 'services.date'
  beforeEach inject (_$date_) ->
    dateService = _$date_

  describe 'Test', () ->
    it 'should test stuff', () ->
      (expect true).toBe true

If I run this code, I get this error:

Firefox 37.0.0 (Ubuntu 0.0.0) Service: dateService Test should test stuff FAILED
    minErr/<@/home/pv/Sites/web/ngbp-coffee/vendor/angular/angular.js:68:12
    loadModules/<@/home/pv/Sites/web/ngbp-coffee/vendor/angular/angular.js:4411:15
    forEach@/home/pv/Sites/web/ngbp-coffee/vendor/angular/angular.js:336:11
    loadModules@/home/pv/Sites/web/ngbp-coffee/vendor/angular/angular.js:4372:5
    createInjector@/home/pv/Sites/web/ngbp-coffee/vendor/angular/angular.js:4297:11
    workFn@/home/pv/Sites/web/ngbp-coffee/vendor/angular-mocks/angular-mocks.js:2172:44

Now here is the interesting part: if I comment on the injection code, the test passes:

describe 'Service: dateService', () ->
  # dateService = null
  # beforeEach module 'services.date'
  # beforeEach inject (_$date_) ->
  #   dateService = _$date_

  describe 'Test', () ->
    it 'should test stuff', () ->
      (expect true).toBe true

// after launch

Firefox 37.0.0 (Ubuntu 0.0.0): Executed 1 of 1 SUCCESS (0.003 secs / 0.002 secs)

Done, without errors.

What happens with the way I introduced the wrong service? Please, help.

UPDATE

It seems that the service $injectorcannot recognize my other service. If i do

$injector.has '$date'

I get false

WTF am I doing wrong ?????

" " , (dateService) (_ $date _). , _ $date_ , "$ date" ( dateService).

. "$ date" . , . , - factory , Karma, , , "$ date" .

( factory, ).
