assert

2つの引数をとり，それらが同じ値かどうかを出力するような関数assert_equalを作る．同様に，それらが異なる値かどうかを出力するような関数assert_not_equalを作る．

assert.rb

require 'colorize'

def puts_vals(expected, result)
  puts "expected :: #{expected}"
  puts "result   :: #{result}"
end

def assert_not_equal(expected, result)
  puts_vals(expected, result)
  if expected != result
    print "succeeded in #{__method__}.\n".green
  else
    print "failed in #{__method__}.\n".red
  end
end

def assert_equal(expected, result)
  puts_vals(expected, result)
  if expected == result
    print "succeeded in #{__method__}.\n".green
  else
    print "failed in #{__method__}.\n".red
  end
end

if $PROGRAM_NAME == __FILE__
  assert_equal(1, 1)
  assert_equal(1, 2)
  assert_not_equal(1, 2)
  assert_not_equal(1, 1)
end

他のソースコードからassertを利用する

require_assert.rb

require './assert'

assert_equal(4, 2 * 2)
assert_not_equal('Muku', 'Miku')
