I was looking at fit.c2.com, which was an idea of using Wiki style development to create acceptance tests. It's also probably there to avoid the tedium of writing one-off (test) code in Java.
Anyway, the example style reminded me very much of doctest. I really like doctest, but it's really not a complete solution for testing. I feel like there should be other ways to express tests in the same spirit as doctest. Fit (at least, I assume that's the name of the framework) seems to have some more flexible ideas about testing fixtures. (Though of course doctest's other great feature is that the fixture for a test is minimal to the point of non-existance)
Anyway, parallel developments are always interesting.
