EmberJS 测试模型

2018-01-03 17:05 更新

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。

     setResolver(Ember.DefaultResolver.create({ namespace: App }));

     //The 'moduleFor' helper is used to setup a test container
     moduleForModel('employee', 'Employee Model');
     test('EmpSalary', function() {
        var employee = this.subject({ Empno: 4 });
            //This is an async function and should be wrapped using 'Ember.run'
            Ember.run(function() {
               employee.EmpSalary();
            });
       //Check the values before we modify the post
       equal(employee.get('Empno'), 5);
       equal(employee.get('EmpName'), 'Manu');
     });

输出

让我们执行以下步骤，看看上面的代码如何工作：

将上面的代码保存在testing_models.html文件中
在浏览器中打开此HTML文件。
