To verify a transport we need a server factory, which is a callable
386
that accepts no parameters and returns an implementation of
387
bzrlib.transport.Server.
389
That Server is then used to construct transport instances and test
390
the transport via loopback activity.
392
Currently this assumes that the Transport object is connected to the
393
current working directory. So that whatever is done
394
through the transport, should show up in the working
395
directory, and vice-versa. This is a bug, because its possible to have
396
URL schemes which provide access to something that may not be
397
result in storage on the local disk, i.e. due to file system limits, or
398
due to it being a database or some other non-filesystem tool.

This also tests to make sure that the functions work with both
401
generators and lists (assuming iter(list) is effectively a generator)
