Write unit tests as cells of IPython notebooks

What?

Plugin for py.test to write unit tests as cells in IPython notebooks:

• Homepage on Github: https://github.com/zonca/pytest-ipynb
• PyPi : https://pypi.python.org/pypi/pytest-ipynb/
• Install with pip install pytest-ipynb

Why?

Many unit testing fromeworks in Python, first of all the unittest package in the standard library, work very well for automating unit tests, but make it very difficult to debug interactively any failed test.

py.test alleviates this problem by allowing to write just plain Python functions with assert statements (no boilerplate code), discover them automatically in any file that starts with test and write a useful report.

I wrote a plugin for py.test, pytest-ipynb, that goes a step further and runs unit tests written as cells of any IPython notebook named test*.ipynb.

The advantage is that it is easy to create and debug interactively any issue by opening the testing notebook interactively, then clean the notebook outputs and add it to the software repository.
