A few days ago, I saw on Grig's blog that Titus created a mailing list covering Testing in Python. I joined the list and it's been very educational. So far the posts have been in the "Hi--my name is _____________ (name) and I use ______________ (framework) and ___________ (framework) and ____________ (explanation for which framework gets used for which specific purposes)." Then this spawns a conversation with thoughts and insights and lots of applause. There have also been questions regarding how to use some of the frameworks and which framework would suit some need the best.
While I'm following the mailing list, I'm taking notes so that I can finish up this round of adding testing to PyBlosxom so that I can do a release this week. We're using nose and I'm using a similar structure that Cheesecake uses since I have some familiarity with their project.
It's a neat list so far. I'm glad Titus put it together--it's definitely solving my immediate needs.
