Ch13 - orange_tree.rb

[emmabeynon]

Hi guys,

I'm having a lot of trouble getting this one to pass. I even tried using the solution code as-is and it still doesn't work. Here's the error:

Emmas-MacBook-Air:learn_to_program emmabeynon$ rspec spec/ch13/orange_tree_spec.rb

OrangeTree
  reports height and number of oranges (FAILED - 1)

Failures:

  1) OrangeTree reports height and number of oranges
     Failure/Error: expect(ot.one_year_passes).to eq 'This year your tree grew to 10.0m tall, and produced 125 oranges.'

       expected: "This year your tree grew to 10.0m tall, and produced 125 oranges."
            got: "Oh, no! The tree is too old, and has died. :("

And here's the solution code:

# note we have added a rounding operation on the height to ensure
# the output is sensible in terms of decimal places

class OrangeTree
  def initialize
    @height = 0
    @orange_count = 0
    @alive = true
  end

  def height
    if @alive
      @height.round(1)
    else
      'A dead tree is not very tall. :('
    end
  end

  def count_the_oranges
    if @alive
      @orange_count
    else
      'A dead tree has no oranges. :('
    end
  end

  def one_year_passes
    if @alive
      @height = @height + 0.4
      @orange_count = 0 # old oranges fall off
      if @height > 10 && rand(2) > 0
        # tree dies
        @alive = false
        'Oh, no! The tree is too old, and has died. :('
      elsif @height > 2
        # new oranges grow
        @orange_count = (@height * 15 - 25).to_i
        "This year your tree grew to #{@height.round(1)}m tall," +
          " and produced #{@orange_count} oranges."
      else
        "This year your tree grew to #{@height.round(1)}m tall," +
          " but is still too young to bear fruit."
      end
    else
      'A year later, the tree is still dead. :('
    end
  end

  def pick_an_orange
    if @alive
      if @orange_count > 0
        @orange_count = @orange_count - 1
        'You pick a juicy, delicious orange!'
      else
        'You search every branch, but find no oranges.'
      end
    else
      'A dead tree has nothing to pick. :('
    end
  end
end
