Template class for tests of the Conch server's ability to forward arbitrary
protocols over SSH.
These tests are integration tests, not unit tests. They launch a Conch
server, a custom TCP server (just an L{EchoProtocol}) and then call
L{execute}.
L{execute} is implemented by subclasses of L{ForwardingMixin}. It should
cause an SSH client to connect to the Conch server, asking it to forward
data to the custom TCP server.
c C s | � dt� �}|�| jd�S )z�
Test that we can use whatever client to send the command "echo goodbye"
to the Conch server. Make sure we receive "goodbye" back from the
server.
