Reshma,
     Looking at this, I think this particular unit test needs to be 
removed. The way it is at the moment, it's "faking" the connect, then 
any commands that are sent to the dummy host are only really to test to 
see if the API breaks, which is going to be captured by compilation 
tests anyway. I don't see the value of this unit test unless you have 
the full host setup underneath is, in which case it's no longer a unit 
test.
Also, we don't want to make these functions public, as they are only of 
use to the library internally, and there is no use for them publicly 
(unless a guest wants to fake a connection to a non-existent host).

What do you think?
Dave.
