PyUnit - the standard unit testing framework for Python

This unit testing framework, dubbed 'PyUnit' by convention, is a Python language version of JUnit. JUnit was written by smart cookies Kent Beck and Erich Gamma, and is, in turn, a Java version of Kent's Smalltalk testing framework. Each is the de facto standard unit testing framework for its respective language, and therefore both are a strong basis for an effective and elegant Python framework.

Testimonials

"PyUnit is cool. It's helping us find lots of bugs." -- Jim Fulton, Digital Creations
"I am really impressed with the effect of unit testing on the quality of my code since I started using PyUnit about two months ago. I know that the extra effort has saved me literally days of looking for subtle bugs. Writing the unit tests first is also a very good innoculation against over-engineering." -- Terrel Shumway

What is it?

Some quick facts about PyUnit:-

Where can I get it?

Update: Unless you're stuck in the year 2000, PyUnit is in your Python standard library as module unittest.

The framework is currently two Python source modules (i.e. no messy installation) and is packaged for download together with documentation and examples. The documentation provides a cookbook for writing tests, usage guidelines, known issues, future plans, and links to sources of related information.

Feedback and discussion via the mailing list is encouraged. This low-volume list is a good place to discuss PyUnit, to ask others about their practises, and to share your wisdom.

Important note for Windows users

Please note that the PythonWin IDE and Tkinter do not co-exist happily. This means the PyUnit GUI should not be run from within PythonWin, otherwise a crash is possible. Instead, run it separately using the standard python.exe or pythonw.exe, or by double-clicking on unittestgui.py in Explorer.

(Of course, using the text mode of PyUnit from PythonWin will work just fine.)
