Question

I’m trying to raise 2 exceptions when one of my variables is bigger than 13 or less than 1
also I want to raise exception if the type of my card is not one of the defined one.
this is my code :

require "../lib/suit"
class Card
    attr_reader :suit,:number
 def initialize(suit,number)
     raise "CardNumberNotValid" if 1>number>13
     raise "SuitNotValid" if suit!=Suit::CLUB or suit!=Suit::HEART or suit!=Suit::DIAMOND or suit!=Suit::SPADE
     @suit=suit
     @number=number
 end
end

and this is my test:

require "rspec"
require "../lib/suit"
require "../lib/card"

describe Card do

  it "should check if card number is between 1 and 13" do
    expect{Card.new(Suit::CLUB,14)}.to raise_error("CardNumberNotValid")
  end
end

The result is below :

Failures:

1) Card should check if card number is between 1 and 13
Failure/Error: expect{Card.new(Suit::CLUB,14)}.to raise_error(“CardNumberNotValid”)
expected Exception with “CardNumberNotValid”, got #’ for false:FalseClass>
# ./card_spec.rb:8

Finished in 0.00064 seconds 1 example, 1 failure

Failed examples:

rspec ./card_spec.rb:7 # Card should check if card number is between 1
and 13

can you please help ?

Answer 1

1>number>13

Does not work in Ruby. Use something like:

number.between?(1, 13)
