mock Connection

[gregwebs]

I would like to run integration tests that don't depend on the network. It appears to me that if I can mock the Connection than I can mock http-client. Do you have any insight on how to initialize a mock connection?

From a quick review of the code, my first try would be use connectFromHandle but give a mock Handle, although now I have to figure out if it is possible to create a mock Handle.

I think it would be really nice to have a connectFromBsMvar that takes a "MVar [Strict.ByteString]" (or a Chan) for this purpose and would be actually quite generic and useful for testing/mocking.

I decided to go with the approach of writing a fake server rather than trying to mock Haskell data types. It makes a lot more sense for my use case.
