How to make the simplest unittests in Python

Testing your code is nearly a requirement (even more so in Ruby). Unittests are now the most vital elements for evaluating the quality/viability of a project. I was a little jealous of Ruby where you don’t have so much to write to implement unittests. Here is a simple example:

require "mymodule"
require "test/unit"

class TestMyModule &lt; Test::Unit::TestCase

  def test_simple
     assert_equal(1, 1 )
  end
end

require "mymodule"

require "test/unit"

class TestMyModule < Test::Unit::TestCase

def test_simple

assert_equal(1, 1 )

Now, using Nose, you can […]

Default behaviour in implementation of STOMP protocol in RabbitMQ with python

Why STOMP? Why STOMP, and not directly AMQP, as I’m using RabbitMQ. No real reason, but the fact that there are less dependencies on a STOMP client, as it’s just a socket with text sent. Implementations There are several implementations of the STOMP protocol for Python. The module I chose is python-stomp (version 0.2.9), from […]

How to dial a number using Asterisk and Python

I didn’t find any example in Python on how to Dial a number from an Asterisk server and link it to another channel. So here’s a quick code to do it. You just need to have a manager defined in your /etc/asterisk/manager.conf defined.

import socket
 
HOST="192.168.1.116"
PORT=5038
 
p = """Action: login
Events: off
Username: %(username)s
Secret: %(password)s
 
Action: originate
Channel: SIP/%(local_user)s
WaitTime: 60
CallerId: 600
Exten: %(phone_to_dial)s
Context: default
Priority: 1
 
Action: Logoff
"""
def click_to_call(phone_to_dial, username, password, local_user):
    pattern = p % {
            'phone_to_dial': phone_to_dial,
            'username': username,
            'password': password,
            'local_user': local_user}
 
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.connect((HOST, PORT))
 
    data = s.recv(1024)
    for l in pattern.split('\n'):
        print "Sending&gt;", l
        s.send(l+'\r\n')
        if l == "":
            data = s.recv(1024)
            print data

Making and deploying a Twisted project as a service under Windows

What is the goal? The goal is to implement a program in Python+Twisted (using PB for network access) under Windows XP or 2000+, that can be run before a user logs on, so it has to be a windows service, launched automatically, at boot. Another goal is to show some developement patterns in Twisted. You […]
