class Test def initialize puts ‘initializing test’ end end class TestB < Test end

class Test

  def initialize 
    puts 'initializing test'
  end

end

class TestB < Test

end

something = Class.new(Test)

In the above, the superclass initialize method is not called. If I do

something = TestB.new

it is called.

    Reading the documentation, Class.new(Test) yields a derived class object which has Test as its superclass.

    You need to call new on that result to get the printout.

    TestA = Class.new(Test)
    something_else = TestA.new
