My main problem with unittesting for languages like this, is that you need to test the entire binary. The dynamic typing means you will be in a lot of trouble if you accidentally return a class of one type but expect something else at some other point. Ie, you need to spend a lot of time either unittesting, or function testing on a very high level (which would come automatically with compiled languages). That said, the eve client is written in python. I haven't even looked at the unit testing framework and how to use it in python yet =) Mmm, maybe I am a tad skeptical, but it’s only opinion.

Sad then that you don't believe in large projects for Python, since I have a great idea in my mind (which I have to keep for myself for now). I was hoping you would participate -- and the project I have in mind will become... very large. Well, we'll see. I am hacking myself into Trac, or around, playing with plugins. Quite fun I would say, and I agree with your observations. Python seems very "hackable", but it also seem very competent. But you are definitely right when your state that the loose (dynamic) typing can cause problems. Unit testing will be a major concern for all Python projects. Perhaps that's why they've included a whole unit testing module? Best regards! Interesting thoughts, Oskar.
