title: cucumber vs. RSpec
body: <p>I want to start diving into BDD. I have never used TDD before and am
  not sure if I should start by learning RSpec and then jump to Cucumber
  or just go straight to using Cucumber.</p>
  
  <p>I have been reading on the internet about both and it seems to me that
  Cucumber could be a 'replacement' for RSpec. Am I right or should be
  one used for certain things and the other one for others?</p>
