testing Twisted code. Instead, you can implement unit test script (using twisted.trial.unittest)
– implementing test versions of your Twisted server and/or client class(es).
This can be done by extending original class(es) and overwriting appropriate
methods (like connectionMade(), connectionLost(), dataReceived(), etc.) –
by adding deferreds and executing callbacks when given event occurs. These
callbacks would be methods within your unittest script (these deferreds would
be instantiated and added to these classes by the test script) – thus allowing
you to test client’s or server’s behavior, or track progress</span></font></p>

<br>
I have a client server model in twisted, where the server spawns a thread (
basically a test script in python that runs for about 20 mins)<br>
I want to track the progress of the thread, and send the progress to the client
back<br>
<br>
So, I write something like this in my server:<br>
<br>
parent_conn, child_conn = Pipe()<br>
thread = Process(target = start_test.main_func, args=(SCRIPT_PATH,
TEMP_OUTPUT_PATH, self.output_name, child_conn))<br>
thread.start()<br>
<br>
response = parent_conn.recv()<br>
print response //prints like: initialization done<br>
self.transport.write(response)<br>
<br>
<br>
response = parent_conn.recv()<br>
print response // configuration done<br>
self.transport.write(response)<br>
<br>
.<br>
.<br>
.<br>
<br>
thread.join()<br>
<br>
<br>
But the transport.write calls don't send at the same time. instead they wait
for the thread to finish (coz of thread.join) and then append all the response
and send it back; like "initialization doneconfiguration done...done"<br>
thereby defeating the purpose of creating a thread.<br>
<br>
How do I give the control to the reactor to write the data back, and still keep
the thread running?<br>
or is there any other way these kinda of progress can be tracked ?<br>
I am kinda stuck with this :(</span></font></p>
