app.js

app = angular.module("myApp", ["service.create"])

controller.js

angular.module("myApp").controller("testCtrl", function($scope, create) {
  return console.log(create);
});

services.breadcrumbs.js

angular.module("service.create", []).factory('create', function() {
  var self;
  self = {
    "status": "hello"
  };
  return self;
});

I will use
angular.module("myApp", ["myApp.controllers", "myApp.services"]);

angular.module("myApp.controllers", ["ui.router"]);

angular.module("myApp.services", ["ui.bootstrap"]);
