Basic Twisted Client-Server with Tests

Twisted is an event-driven networking engine written in Python.

This is an invetsigation of test-driving custom client-server code with twisted, following the examples from the Test-driven development with Twisted tutorial.

Installing and Running the Tests

$ pip install -r requirements.txt
$ nosetests
Ran 17 tests in 0.145s


Using the Calculus Server

$ export PYTHONPATH="$PYTHONPATH:`pwd`/calculus"
$ python calculus/
2016-04-18 20:47:08+0800 [-] Log opened.
2016-04-18 20:47:08+0800 [-] RemoteCalculationFactory starting on 58522
2016-04-18 20:47:08+0800 [-] Starting factory <__main__.RemoteCalculationFactory instance at 0x10a4fb488>

in another window:

$ telnet localhost 58522
Connected to localhost.
Escape character is '^]'.

or with netcat (since telnet becoming vanishingly rare!)

$  nc -c localhost 58522
subtract 12345 4123
add 4123 8222

This page is a web-friendly rendering of my project notes shared in the LittleCodingKata GitHub repository.

LittleCodingKata is my collection of programming exercises, research and code toys broadly spanning things that relate to programming and software development (languages, frameworks and tools).

These range from the trivial to the complex and serious. Many are inspired by existing work and I'll note credits and references where applicable. The focus is quite scattered, as I variously work on things new and important in the moment, or go back to revisit things from the past.

This is primarily a personal collection for my own edification and learning, but anyone who stumbles by is welcome to borrow, steal or reference the work here. And if you spot errors or issues I'd really appreciate some feedback - create an issue, send me an email or even send a pull-request.
