Sails.js unit-test

I am building web application using Sails.js.

and I also building unit-test environment based on this site. (http://ift.tt/1AUCQMg)

When I try to Controller test below, message says like this. ※ I am using wolfpack as testing framework.

1) The UserController should return a HTTP 200 response if the user was added successfully:
 ReferenceError: runs is not defined
  at Context.<anonymous> (my_project_path/test/controllers/UserController.spec.js:42:9)

2) The UserController #create ユーザーが作成されるはず:    
ReferenceError: sails is not defined
  at Object.module.exports.create (my_project_path/api/controllers/UserController.js:9:457)

I don't know why error message says " ReferenceError: runs is not defined" or "ReferenceError: sails is not defined" because I uncommented sails:true in global.js for global use.

please anyone help me. (and I apologize for my bad English... I am learning English now ;_;)

here is my Controller test code.

var UserController = require('../../api/controllers/UserController'),
    sinon = require('sinon'),
    constant = require('../../config/const'),
    User = require('../../api/models/User'),
    wolfpack = require('wolfpack');

global.User = wolfpack(User); 

var request = {
    params: {
        username: 'testuser',
        email: 'testuser@test.com',
        familyname: 'test',
        firstname: 'user',
        gender: constant.constVal.gender.male,
        subscription: true,
        term: true
    }
};

var response = {
    send: sinon.stub() 
};

describe('The UserController', function() {
    describe('#create', function() {
        it('ユーザーが作成されるはず', function() {
            UserController.create(request, response);

            expect(User.username.lastCall.args[0]).toBe(request.params.username);
            expect(User.email.lastCall.args[0]).toBe(request.params.email);
            expect(User.familyname.lastCall.args[0]).toBe(request.params.familyname);
            expect(User.firstname.lastCall.args[0]).toBe(request.params.firstname);
            expect(User.gender.lastCall.args[0]).toBe(request.params.gender);
            expect(User.subscription.lastCall.args[0]).toBe(request.params.subscription);
            expect(User.term.lastCall.args[0]).toBe(request.params.term);
        })
    });

    it("should return a HTTP 200 response if the user was added successfully", function() {
        // Run first part of test asynchronously (jasmine function)
        runs(function() {
            UserController.create(request, response);
        });

        // When the callback executes, it should call res.send, so we should wait for it
        waitsFor(function() {
            return response.send.called;
        });

        // Now we can test if the proper code was sent
        runs(function() {
            expect(response.send.lastCall.calledWith(200)).toBeTruthy();
        });
    });
});
