Asp.net mvc 2 IntegrationTests-潜在危险的请求。从客户端检测到路径值

我收到以下错误：

一个潜在危险的请求。当此URI:
http://www.site.com/%3f

如何编写针对所有此类错误的集成测试？

我想针对所有这些错误进行测试：

A potentially dangerous Request.Path value was detected from the client
A potentially dangerous Request.Cookies value was detected from the client
A potentially dangerous Request.Form value was detected from the client
A potentially dangerous Request.QueryString value was detected from the client

你到底想测试什么？您的应用程序如何对某些断开的URL作出反应？
