I did some research regarding the ruby dsl (domain specific language)
for testing. I think I was mostly thinking about rspec that defines a
dsl which lets you define tests in a very natural and easy way. However
some more research seemed to reveal that in Python it is much harder to
create a dsl, but there are other options to do testing in Python:
1. write your tests using Python unit test
(http://docs.python.org/release/2.6.5/library/unittest.html)
2. write some kind of data structure that is interpreted by Python (your
proposal)
3. write the tests in some form of csv which is read by the Python csv
module and then interpreted by Python (my original proposal)
4. write doctests
(http://docs.python.org/release/2.6.5/library/doctest.html)
5. Write tests using pytest (http://pytest.org/latest/contents.html)

What I liked about proposal 3 is that it is very concise and lets you
define tests very easily (even for a non-programmer). I thought the csv
module alleviates some of the drawbacks of using a lose format such as
csv (quote handling, delimiters, etc). Csv is very easy for the simple
cases.
But looking at the other choices I'd say for our case option 4 is
probably best. It is fairly concise and it is a standard. Pytest seems
also very nice and could be grafted on top of your proposal at a later
stage.
I'll have to think about it some more but I'm coming to the conclusion
that we should delay this discussion about testing frameworks. We should
use your tests, see how they are used and then if need be migrate to a
test framework at a later point.
Thanks
