[Grok-dev] Testing a container which uses a custom NameChooser

[Luciano Ramalho]

One component of Kirbi is the Pac (public access catalog, a book
container), defined here:

http://svn.zope.org/Sandbox/luciano/kirbi/src/kirbi/pac.py?rev=78499&view=markup
(or http://tinyurl.com/3ybsed)

It's method addBook uses a custom NameChooser defined in the same
module. This is working, but I've been unable to write a unit test for
it.

The simple test contained in this file:

http://svn.zope.org/Sandbox/luciano/kirbi/src/kirbi/tests/test_pac.txt?rev=78499&view=markup
(or http://tinyurl.com/3xu8wt)

... breaks with the messages below. What am I missing in the doctest
to make it pass?
