惩戒的Htt prequest在ASP.NET 4.0 [英] Mocking HttpRequest in ASP.NET 4.0

问题描述

我见过很多类似的线程，但没有实际解决我的特殊情况。

I've seen a lot of similar threads but none that actually address my particular situation.

我正在写在ASP.NET 4.0 Web应用程序的单元测试（ASP.NET窗体，而不是MVC）。有在code几个景点，我称之为 ServerVariables 收集调用像 REMOTE_ADDR 变量。由于我的单元测试并没有真正启动的Htt prequests 执行我的code时，像 ServerVariables 是空，因此错误，当我尝试调用 HttpContext.Current.Request.ServerVariables（REMOTE_ADDR）

I'm writing unit tests in ASP.NET 4.0 web application (ASP.NET Forms, not MVC). There are several spots in the code where I call the ServerVariables collection to call variables like REMOTE_ADDR. Since my unit tests do not actually initiate HttpRequests when executing my code, things like ServerVariables are Null and therefore error when I try to call HttpContext.Current.Request.ServerVariables("REMOTE_ADDR")

我已经找到解决这一问题的参考MVC，所以他们认为的Htt prequest 从的Htt $导出所有解决方案p $ pquestBase ，其中它在MVC，但不是在ASP.NET窗体。

All the solutions I've found to address this issue refer to MVC and so they assume that HttpRequest derives from HttpRequestBase, which it does in MVC but not in ASP.NET Forms.

我试着用起订量，但你不能嘲笑密封类，而的Htt prequest 是遗憾的是，没有接口密封。

I tried using Moq but you can't mock a sealed class, and HttpRequest is unfortunately sealed with no interface.

推荐答案

的<一个href=\"http://msdn.microsoft.com/en-us/library/system.web.htt$p$pquestbase.aspx\"><$c$c>Htt$p$pquestBase和<一个href=\"http://msdn.microsoft.com/en-us/library/system.web.htt$p$pquestwrapper.aspx\"><$c$c>Htt$p$pquestWrapper类可以有一些工作可以使用。

The HttpRequestBase and HttpRequestWrapper classes can be used with a bit of work.

- 或者只是简单的 Page.Request - 你会需要使用的Htt prequestBase 的注射实例，而不是。然后你将需要注入的Htt prequestBase 这取决于你正在测试或现场不同的子类。

Wherever you currently access HttpContext.Current.Request -- or just plain Page.Request -- you'll need to use an injectable instance of HttpRequestBase instead. Then you'll need to inject a different subclass of HttpRequestBase depending on whether you're testing or live.

• 有关现场code，你可能会注入一个包装了的Htt prequestWrapper 实例 HttpContext.Current。请求：

var liveRequest = new HttpRequestWrapper(HttpContext.Current.Request);

有关测试code，你需要创建和注入的Htt prequestBase 你自己的模拟子类。 presumably起订量可以为你做的即时。

For test code, you'd need to create and inject your own mock subclass of HttpRequestBase. Presumably Moq can do that for you on-the-fly.
