Wow. I’ve only been at RubyConf 2005 for one day here in San Diego, and I’ve already learned quite a lot. Hanging out with some brilliant co-workers of mine, I was introduced to Dave Astels’ Behaviour-Driven Development, a re-thinking of how to look at Test-Driven Development. Some fellow Rubyists (including Dave), of course, have already implemented this for Ruby in the form of RSpec. I’ve already changed my thinking about testing quite a lot since joining ThoughtWorks, but this is by far the most exciting testing-related thing I’ve come across since Test::Unit came out.

RSpec feels much more rubyish than Test::Unit does. It speaks more to the reader about what the intent of the code under test is, reads from left to right, depends on Ruby’s “everything is an object”, and is small and beautiful. Now I just have to avoid the temptation to go instantly rewrite everything I have to use RSpec. Unless ThoughtWorks is willing to give me a couple of months off, of course.

Speaking of testing and ThoughtWorkers: Obie apparently doesn’t think my mock object library is “real”. Damn those imaginary libraries.

Looking forward to Day 2!
