使用Mocha测试Ember - visit（）会导致测试中止

Question

运行visit()时，Ember过渡正确： Transitioned into 'auth'，

然而，PhantomJs不加载： [D] ["phantomjs","onLoadFinished","fail"]

如何解决这个问题，为什么visit()不起作用？

细节：

在使用yo ember生成的项目中，我有以下测试规范：

    var assert = chai.assert;
    var expect = chai.expect;
    var should = chai.should();

    App.rootElement = '#main';
    App.setupForTesting();
    App.injectTestHelpers();

    (function () {
        'use strict';

        beforeEach(function() {
            Ember.run(function() {
                App.reset();
            });
            Ember.testing = true;
        });

        afterEach(function() {
            Ember.testing = false;
        });

        describe('Basic', function () {

            describe('Smoke test', function() {
                visit('/auth');

                it('Should contain a header', function() {
                    expect($('.main').length).to.equal(1);
                });
            });
        });
    })();

当我运行grunt test --debug时，我得到以下输出：

    [D] ["phantomjs","console","generated -> controller:application [object Object]"]
    generated -> controller:application [object Object]
    [D] ["phantomjs","console","Rendering application with default view <(subclass of Ember.View):ember650> [object Object]"]
