Feature: customized message

In order to get the feedback I want
As an RSpec user
I want to customize the failure message per example

Scenario: one additional method
  Given a file named "node_spec.rb.rb" with:
    """
    class Node
      def initialize(state=:waiting)
        @state = state
      end
      def state
        @state
      end
      def waiting?
        @state == :waiting
      end
      def started?
        @state == :started
      end
      def start
        @state = :started
      end
    end

    describe "a new Node" do
      it "should be waiting" do
        node = Node.new(:started) #start w/ started to trigger failure
        node.should be_waiting, "node.state: #{node.state} (first example)"
      end

      it "should not be started" do
        node = Node.new(:started) #start w/ started to trigger failure
        node.should_not be_started, "node.state: #{node.state} (second example)"
      end
    end

    describe "node.start" do
      it "should change the state" do
        node = Node.new(:started) #start w/ started to trigger failure
        lambda {node.start}.should change{node.state}, "expected a change"
      end
    end

    """
  When I run "spec node_spec.rb.rb --format specdoc"
  Then the stdout should include "3 examples, 3 failures"
  And  the stdout should not match "to return true, got false"
  And  the stdout should not match "to return false, got true"
  And  the stdout should include "node.state: started (first example)"
  And  the stdout should include "node.state: started (second example)"
  And  the stdout should include "expected a change"
