Mock up an angular module so a factory can be tested - angularjs

Question

I am trying to unit test a service without depending on my application module. How is this supposed to work?
Code:
#karma.conf.coffee
files: [
'bower_components/angular/angular.js' # angular core
'bower_components/**/angular-*.js' # all angular plugins
'utils/typometer.js'
'utils/typometer.spec.js'
]
# utils/typometer.coffee
angular.module('myApp').factory 'typometer', ->
#sizes =
'A':8
'B':9
# # return `this`
# utils/typometer.spec.coffee
describe 'typometer', ->
typometer = undefined # scope control
# Create a mock module so that the typometer factory has something to attach to
beforeEach angular.mock.module 'myApp' #TODO: why doesn't mock.module work?
# Inject the typometer service
beforeEach angular.mock.inject (_typometer_) ->
typometer = _typometer_ # http://docs.angularjs.org/api/angular.mock.inject
it 'exists', ->
expect(typometer).toBeDefined() # fail. 'Uncaught Error: [$injector:nomod] Module 'coatue' is not available!'
expect(typometer.sizes.A).toEqual 8
The ultimate goal is to be able to instantiate a typometer service and test it in isolation without standing up a real instance of the myApp module.
I think this is some kind of order of operations issue. When the typometer factory is declared, the module doesn't exist--I want to test my production files though. Do I have to create a shell application or load the real one before loading any of the files under test? This is a dependency that I would like to remove from the test considerations.

Answer 1

I think I understand now. For a working setup, one needs to perform all of the following:
Load angular + angular plugins
Load dependent module definitions (eg: myApp). This is what I missed.
Load files to test
Load specs
Have test specs instantiate dependent modules and injectables under test
This is a working setup:
#karma.conf.coffee
files: [
'bower_components/angular/angular.js' # angular core
'bower_components/**/angular-*.js' # all angular plugins
'main.js' # still need to load the app definition
'utils/typometer.js'
'utils/typometer.spec.js'
]
# utils/typometer.coffee
angular.module('myApp').factory 'typometer', ->
#sizes =
'A':8
'B':9
# # return `this`
# utils/typometer.spec.coffee
describe 'typometer', ->
typometer = undefined # scope control
beforeEach ->
angular.mock.module 'myApp' # instantiate the mock app
angular.mock.inject (_typometer_) -> # instantiate the mock service
typometer = _typometer_ # http://docs.angularjs.org/api/angular.mock.inject
it 'exists', ->
expect(typometer).toBeDefined()
expect(typometer.sizes.A).toEqual 8
