Getting started with IronPython - Part 3: unit testing

By Michael Foord -
This is the third part of Dror Helper's series on getting started with IronPython. Part 1 was on first steps, including useful references. Part 2 focused on the Python programming language, introducing an example game project that Dror is using to learn IronPython. As promised part 3 is on testing the game with the Python unittest module.
Being a TDD’er (Test Driven Developer) one of the first things I’ve searched for when I started learning IronPython is a unit testing framework, luckily for me I didn’t need to search too long.

IronPython has a good unit testing framework inherited from Python called PyUnit.

Writing unit tests using PyUnit is simple:
  1. import unittest class
  2. Create a class that inherits unittest.TestCase (test fixture)
  3. Write test methods using assertions methods

I never met Michael in person, but we communicated online about all things Python. He was one of the most prolific contributors to this blog during the heyday of IronPython. If you use Python, chances are you've benefited from something Michael contributed to the ecosystem. I will miss you, "Fuzzyman." In memoriam: Michael Foord

Extending Abobe Flash Player and AIR with Python and Ruby

By Michael Foord -
An intriguing blog entry about an Adobe experimental project. It is a C/C++ cross- compiler for the flash player and AIR. This means that you can (will be able to?) cross-compile the Python / Ruby/ lots of other language runtimes and then run them in Flash. The blog entry contrasts this approach to the DLR which requires the re-implementation of dynamic languages - hence IronPython and IronRuby. The project is already beyond proof-of concept, they even have Quake III cross-compiled and running in Flash. Extending Adobe Flash Player and AIR with C/C++ Cross-Compiler Quake 3 has already been ported to managed code , but this is even more impressive. Whether the Python interpreter can be cross-compiled to run on top of another runtime (with completely different basic types), without changing the language semantics at all, has yet to be proved - but it is a very interesting project. (It also means that Python/Ruby will possibly be enabled only by additional optional downloads - but don...

Further Adventures of the Debugger

By Michael Foord -
Harry Pierson (Microsoft IronPython PM) has been experimenting with writing an IronPython debugger ( ipydbg ) on top of the .NET MDbg APIs. When we last left him , he had implemented Just My Code (JMC) support allowing you to step into IronPython code. Since then he has made a lot of progress including a colourful REPL (interactive console) and solving some difficult problems around getting to real values behind boxed IronPython variables (needed for showing local variables). He has blogged extensively on what he has been up to (more recent posts last): Showing Source Code Colorful Console IronPython ConsoleColorMgr (the colorful console code pulled out into a separate IronPython module) A Little Hack...err...Cleanup Getting Local Variables Displaying Values Command Routing Getting Arguments REPL Console A lot of functionality is now present. In the command routing entry Harry outlines the seven commands supported by the debugger so far: Continue, Quit, Show Stack Trace, Show Locals, ...
