Ruby

instance_evalが面白い

こういうのはgithubにいれたらいいのか。。。
expectationsは書きやすい。

require "rubygems"
require "expectations"

class Project
  attr_accessor :room_id

  def initialize(room_id)
    @room_id = room_id
  end
end


Expectations do
  expect 10 do
    project = Project.new(10)
    project.instance_eval("room_id")
  end
end

rubyのクラスメソッドとprivateメソッドの違い

ごちゃごちゃしたのでメモ。当たり前なんだけれども

require "rubygems"
require "expectations"

class Hoge
  def self.hello_hello
    "hello"
  end

  private
  def hello
    "hello"
  end
end


Expectations do
  expect true do
    Hoge.private_instance_methods.include?("hello")
  end

  expect true do
    Hoge.public_methods.include?("hello_hello")
  end
end
