测试模型

在Ember中，每个路由都有一个模型，通过实现路由的“模型”钩子来设置。 Ember的模型可以使用moduleForModel帮助程序进行测试。

            //This is an async function and should be wrapped using 'Ember.run'
            Ember.run(function() {

            });
       //Check the values before we modify the post
       equal(employee.get('Empno'), 5);
       equal(employee.get('EmpName'), 'Manu');
