Use

Run ipython notebook, then start your notebook with this import:

In [1]: from ipython_doctester import test

In each subsequent cell, set up objects with their doctests, and with absent (or flawed) function bodies, and decorate them with @test:

In [2]: @test
        def square(x):
            '''
            >>> f(2)
            4
            '''

Tests will run on each cell as it is executed.

If you want to track students’ progress through a notebook in a classroom setting, you can; see http://ipython-docent.appspot.com/ for instructions.

If no doctests are found in the function’s docstring, the program will look for a file ./docstrings/<function name>.txt, append that to the function’s docstring, and check for doctests again. This can be used to keep the presence of the docstrings from confusing students.
