[LRUG] Cucumber and RSpec on Rails

Mon Feb 8 14:54:07 PST 2010

Joseph Wilk's talk at Scotland On Rails last year is a *really* good intro
into how features and tests (both controller and model) sit together
properly.  I'd highly recommend watch it to get a grip on how you should
approach things, although if you aren't into watching videos, Neil has
pretty much nailed it (although he doesn't mention model tests).

Watch it here:
http://scotland-on-rails.s3.amazonaws.com/1A06_JosephWilk-SOR.mp4

One thing to note is that in most Railscasts Ryan Bates isn't showing you
the golden path of the true developer, just how to use the gem or library
he's covering in that episode.  Accordingly he hardly ever writes tests,
unless it's a testing library or gem he's showing off.  So it's not
surprising that in the cucumber episodes he doesn't do unit tests, as, in
theory, you already know how to write those, what you want to learn is how
to write cucumber features.
