Sometimes you want to focus on just one example in your RSpec file. I had to do this quite often in the last 3 days and I got tired of commenting out stuff back and forth. So, I give you “it_only” example.

module Spec
  module DSL
    module BehaviourEval
      module ModuleMethods
        def it(description = :__generate_description, opts = {}, &block)
          return if @it_only_found
          examples << Example.new(description, opts, &block)
        end

        # Same as +it+ only blocks all other examples making this the
        # only example that would run.
        def it_only(description = :__generate_description, opts = {}, &block)
          @it_only_found = true
          @examples = [Example.new(description, opts, &block)]
        end
      end
    end
  end
end

Drop this into your spec_helper.rb and now if you want to focus on a single example, just make it “it_only” instead of “it“.
