What is the most complete mocking framework for HttpContext

Question

I'm looking for as comprehensive as possible of a mock replacement and wrapper for the ASP.NET HttpContext in my applications. A comprehensive mock replacement could potentially increase the testability of my ASP.NET web applications substantially, without necessitating migrating every application to more-testable frameworks such as MVC.

Some of the features I am most interested in seeing in an HttpContext wrapper and mock framework include:

• Serialized session storage (e.g., .Session).
• Serialized application-scoped storage (e.g., .Application).
• Per-request item storage (e.g., .Items).
• HttpRequest data, such as referrers, request Uri, server variables, post data, etc.
• HttpResponse data, such as status codes and content.
• Local file resolution (e.g. Server.MapPath)
• VirtualPathUtility for application-relative URL path resolution, which has a dependency on the ASP.NET runtime.
• The identity and principal (e.g., .User) for validating authentication/authorization rules.
• The AllErrors collection for testing error resolution in HttpModules and Global.asax.

I considered writing my own interface, wrapper, and mock; however, I believe such must already exist. The variety of mock frameworks is a little overwhelming for a first-timer to absorb.

What is the most comprehensive HttpContext wrapper and mock that you would recommend?

Answer 1

My company have done well with just creating interfaces for all the http objcets (IHttpRequest, IHttpResponse, etc).

It's a bit repetative but basically need all methods and properties on the interface then create a concrete type for each which takes the real type as a constructor parameter and passes all methods and properties through to the real object.

Then you can test everything with ease using RhinoMocks or whatever..
