assert("Enumerable#first") does not test Enumerable#first, tests Array#first

[suzukaze]

I write a debug message in Enumerable#first method because I make sure that Enumerable#first is call in test.

mruby-enum-ext/mrblib/enum.rb

  def first(n=NONE)
    puts "first"

mruby-enum-ext/test/enum.rb

assert("Enumerable#first") do
  a = [1, 2, 3]
  assert_equal 1, a.first
  assert_equal [1, 2], a.first(2)
  assert_equal [1, 2, 3], a.first(10)
  assert_nil [].first
end

$ rake test

...
>>> Test host <<<
mrbtest - Embeddable Ruby Test

"first" is not displayed.

I change first method to first2 in Enumerable class.

mruby-enum-ext/mrblib/enum.rb

  def first2(n=NONE)
    puts "first"

mruby-enum-ext/test/enum.rb

assert("Enumerable#first") do
  a = [1, 2, 3]
  assert_equal 1, a.first2
  assert_equal [1, 2], a.first2(2)
  assert_equal [1, 2, 3], a.first2(10)
  assert_nil [].first2
end

$ rake test

...
>>> Test host <<<
