 ===== Testing =====
+The idea is to:
+  * Open a terminal and check that the ''DISPLAY'' environment variable is correctly defined on the local machine
+  * Connect to the remote machine
+  * Check that a (new) ''DISPLAY'' variable is defined on the remote machine
+  * Check that you can start an application using graphics (e.g. ''xterm'') on the remote machine
+==== On a Linux computer ====
+Some basic commands in a terminal
+<code>[Local] $ hostname
+name_of_your_local_machine
+[Local] $ echo $DISPLAY
+:0
+[Local] $ ssh -X some_login@some_remote_server
+[some connection information skipped here]
+[Remote] $ hostname
+name_of_the_remote_server
+[Remote] $ echo $DISPLAY
+localhost:20.0
+[Remote] $ xterm</code>
+==== On a Windows computer with only an X server installed ====
+Some basic commands in a ''Powershell'' (''Start'' => ''Windows Powershell'' => ''Windows Powershell'')
+<code>PS C:\> $env:computername
+name_of_your_local_machine
+PS C:\> $env:DISPLAY
+PS C:\> $env:DISPLAY="localhost:0"
+PS C:\> $env:DISPLAY
+localhost:0
+PS C:\> ssh -Y some_login@some_remote_server
+Warning: No xauth data; using fake authentication data for X11 forwarding.
+[some connection information skipped here]
+[Remote] $ hostname
+name_of_the_remote_server
+[Remote] $ echo $DISPLAY
+localhost:19.0
+[Remote] $ xterm</code>
   * Check the machine name, and check if the ''DISPLAY'' variable is defined
