Python doctest combines unit testing with documentation. With doctest, you put your unit tests in the Python docstring, and documentation generators like Sphinx render your tests as usage examples. It’s easy to compare a method’s output to an XML string using doctest. It’s not so easy when you want the XML string pretty-printed for the sake of clear documentation. Here is a simple solution.More
PyQt is the Python binding of the popular Qt cross-platform UI and application framework. For unit testing, PyQt clients are expected to use the standard Python unittest module, with just a little help from the PyQt QtTest module. It is not immediately apparent how to blend these two frameworks into a unified unit testing strategy. In this article, I show you how to unit test a PyQt GUI dialog using only modules included in PyQt and Python.

It was during my first job as a computer technician in high school that I developed the maxim: first check power, then check clocks.More
When I was about four, we vacationed at the Handerly Hotel & Resort in San Diego (formerly the Stardust Motor Hotel). That place was heaven on earth as far as I was concerned. I loved the pool. Next to the pool there was a bar, and behind the bar was an underwater theater. It was here that I saw one of the most outlandish scenes I have ever witnessed.
At DAC 2011 I gave a presentation on the architecture of oaScript at Si2’s OpenAccess Scripting Language Workshop.
By default SWIG generates C# and Java code that does not support downcast for polymorphic return types. I found a straightforward way to solve this, provided your C++ code has a way to identify the concrete class of the C++ instances that are returned. That is, this technique will work only if the C++ API you are wrapping with SWIG has something similar to C# object.GetType() or Java Object.getClass().More
When you try to install files for East Asian languages, you are asked for a Windows XP installation disk. New computers have shipped with Windows pre-installed for a long time now, so few people have a physical Windows XP disk. Here’s how to install without the DVD/CD-ROM.

Cross-platform CMake can generate a wide variety of build systems. The CMake 2.8 project generator for Eclipse does not work, so you must create the project and configure it to build with GNU Make. Here’s how to do it on Linux.More
CMake creates software build systems for a wide variety of platforms based on a single, unified control file–it’s a makefile maker. You create the CMake control file once and based on this file, CMake will create almost any build environment for you: GNU Make for Linux, Eclipse project, Visual Studio solution for Windows, and the list goes on.More
In this article I show you how to use multilingual UTF-8 strings with standard, unmodified OpenAccess oa-22.04p028 release.
In the last article, I introduced UTF-8, the popular 8 bit encoding of Unicode into multibyte character strings that can represent virtually every written language in history. I presented the OpenAccess software changes required to fully support UTF-8 and showed you how to convert your existing application software to properly manipulate UTF-8 in the OpenAccess oaString class.More
