Comment (by juga):

 Test that Psiphon 3 [0] is working properly.

 The test must:
 * execute the Psiphon 3 client command
 * check that the output text of the command match the expected output text
 * check that is possible to make an HTTP request using the Psiphon3 SOCKS
 proxy

 Open questions are:
 * should the test install the client too?
 * which could be the possible failures bootstrapping Psiphon 3 client?
 * what debug information can we get from the software that would allow us
 to understand why and how it is being blocked ?


 Psiphon 3 has a python client that can be run in linux. [1]
 It uses SSH dynamic port forwarding to create a local SOCKS proxy.
 It can use the system ssh command or the one provided in the Server code.
 By default the SOCKS proxy listen on 0.0.0.0:1080, but this can be changed
 in the psi_client.py

 Add documentation/script about the installation process here?
