Easy way to create a Request to feed to unit tests?

Pretty much what the title says. It would be nice to have a function that makes it easy to create a Request to hand to my various handler functions. As it is, creating a Request using new() requires a HttpRequest from hyper, which requires a NetworkStream... It'd be nice to have a good way to essentially forge a request with no network connection actually involved.

Okay, so here's the skinny...

Creating a Request requires a HttpRequest, which is a Hyper server::Request as documented here: http://hyper.rs/hyper/v0.9.12/hyper/server/request/struct.Request.html

Request::new() uses the deconstruct() method of the HttpRequest to get the various bits and pieces it needs. Namely, (SocketAddr, Method, Headers, RequestUri, HttpVersion, HttpReader<&'a mut BufReader<&'b mut NetworkStream>>). All of these are trivially constructed except for the HttpReader which contains the body of the request... BUT, it just takes any Read object, not necessarily a BufReader containing a NetworkStream. So we can easily create an in-memory buffer and build a HttpReader around that, and just go from there.

Addendum: It's not quite that straightforward since the actual Request type stores the HttpRequest, for some reason, and a bit of type-foolery has to be done to deal with this. Ownership also gets sticky.

I guess the HttpRequest is removed in version 0.3.0. Something like supertest would be good.
