angular.module('MM_Graph')
  .run ($httpBackend)-> 
    $httpBackend.whenGET('/api/v1/project/schema/bsimm').respond { a: 422}

# in one line
angular.module('MM_Graph').run ($httpBackend)-> $httpBackend.whenGET('/aaaa').respond { a: 44}

test

  it 'test', ->    
    inject ($httpBackend, MM_Graph_API)->
      MM_Graph_API.project_Schema 'bsimm', (data)->
        console.log data

    inject ($http)->
      $http.get('/aaaa').then (response)->
        console.log response.data.assert_Is a: 42

      inject ($httpBackend)->        
        $httpBackend.flush()
