What do you mean exactly ? Something like using Gherkin (e.g. Lettuce)
to describe user stories ?

If that's the case I agree ... *when* this is worthy , of course .
Otherwise , I look forward to know what are your ideas about .

Well , it's not quite a big deal for the time being . IMO the first /
cheapeast step towards testing + CI is to run Trac test suite with
Bloodhound patches applied .

Let me check ... oh yes !
Now I see . That's the way I write doctests for Trac plugins . All of
them rely on a custom mini-framework built on top of dutest module
[1]_ , but the version I used is not publicly available yet .

nope .

fwiw Trac uses twill , so you can learn if you want by reviewing their code

IMO , yes .

If you ask me go with twill ... that should be more than enough and
you'll also be able to reuse Trac shared fixture infrastructure , and
everything else they have been building since time ago .
