The first section is the advocacy section; it will begin with
"if you already do unit tests, you may want to skip this
section". I'm not sure if the history lesson is out of scope,
but "Why do you want to use it" is probably better.

I'll explain that one of the benefits of unit testing
extensively is that you can modify your code without fear
(you'll know when it breaks). This section is more advocacy

No, you can't do a lot without interfacing with Zope. I'd add
an example *after* interfacing with Zope. Or both, perhaps.
Maybe one example in the end of each subsection, so we don't
need any subsection titled "example".

A method where you make many tests in a single TestCase class.
You setup a situation (the "fixture") in a method named
"setup", then you do the tests, then you clean up in a method
named "teardown". In the HiperDom tests, for example, I use a
Fixture to do most of the tests, because I initialize the
Template object in setup.

I don't consider this a bug in either Zope or ZUnit, it's just
When you use "keep the objects" so that ZUnit doesn't delete
the temp objects, *and* you use Fixtures, you can get problems
with duplicate Ids, because the user wants to keep one object
for each test, and "setup" usually creates objects with a fixed
name. So, you have to either not use a fixed name on "setup",
or use a fixed name and rename it to something unique in
I allocated a subsection for this because just explaining the
problem is already somewhat convoluted, as you see above ;-) in
a printed book, I'd make it a sidebar or something, but...
