Jay Fields' Thoughts

Constantize tries to find a declared constant with the name specified in the string. It raises a NameError when the name is not in CamelCase or is not initialized.

Examples

• "Module".constantize #=> Module
• "Class".constantize #=> Class

require 'rubygems'
require 'active_support'
require 'test/unit'
require 'dust'

unit_tests do
  class Klass
  end

  test "constantize a string representation of a class" do
    assert_equal Klass, "Klass".constantize
  end
end
