Autospec

Autospec automatically runs your specs (specifications) as you write your code (only running the specs associated with the code you just saved). I keep autospec running on my second screen continuously. This approach makes the BDD process easier to follow.

I installed Autospec using the follow approach:
  sudo gem install ZenTest
  sudo gem install autotest-rails

I did run into an issue when I ran autospec within my rails project root folder:
Unable to find autotest. Please install ZenTest or fix your PATH

I located the executable:
sudo find -name 'autotest'

Next I added the executable's path to my .bashrc:
export PATH="$PATH:/var/lib/gems/1.8/bin"
