Best practices for HttpContext and testable controllers in ASP.Net MVC

Question

I'm leaning towards HttpContextBase. Mainly because I think it was invented for just this reason: testability. And why reinvent the wheel when there's an acceptable solution already out there.

If you put a lot of effort into your wrapper classes around HttpContext, you'd end up with something very similar to HttpContextBase...
