嘲讽的HttpContext检索项表单上下文项词典 [英] Mocking HttpContext to retrieve item form contexts item dictionary

问题描述

我们使用MVC3，为我们在单元测试中使用RhinoMocks的单元测试。
当一个请求开始我们检查从它来和匹配给客户的域。
该客户存储于HttpContext.Items。
大多数控制器需要这个信息，以做好自己的事情。

We use MVC3, for our unit tests we use RhinoMocks in our unit tests. When the a request starts we check the domain from which it came and match that to a customer. This customer is stored in the HttpContext.Items. Most controllers need this info to do their thing.

var mocks = new MockRepository();
using (var controller = new TestController())
{
    HttpContext context = 
        MockRepository.GenerateStub<HttpContext>();

    Customer customer = new Customer { Key = "testKey" };
    context.Items["Customer"] = customer;

    controller.ControllerContext = 
        new ControllerContext { 
            Controller = controller, 
            RequestContext = 
                new RequestContext(
                    new HttpContextWrapper(context), 
                    new RouteData()
                    ) 
        };
       ...

这code样本显示基本上需要什么，但是存根不允许作为HttpContext的是密封类。
该控制器接受HttpContextBase（有很多关于嘲笑这一个），但它不公开的项目属性。

This code sample shows basically what is needed, however the stub is not allowed as HttpContext is a "sealed" class. The controller accepts a HttpContextBase (there is lot about mocking this one), but it does not expose the Items property.

思考的人？甚至更好的解决方案; - ）

Thoughts anyone? Or even better a solution ;-)

推荐答案

创建 HttpContextBase 存根和存根其项目属性将允许您使用项目词典：

Creating a HttpContextBase stub and stubbing its Items property will allow you to use the Items dictionary:

        HttpContextBase context =
            MockRepository.GenerateStub<HttpContextBase>();

        Customer customer = new Customer { Key = "testKey" };
        context.Stub(c => c.Items).Return(new Dictionary<string, object>());
        context.Items["Customer"] = customer;
