By default, camelize converts strings to UpperCamelCase. If the argument to camelize is set to ":lower" then camelize produces lowerCamelCase.

camelize will also convert ’/’ to ’::’ which is useful for converting paths to namespaces

Examples

• "active_record".camelize #=> "ActiveRecord"
• "active_record".camelize(:lower) #=> "activeRecord"
• "active_record/errors".camelize #=> "ActiveRecord::Errors"
• "active_record/errors".camelize(:lower) #=> "activeRecord::Errors"

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

unit_tests do
  test "change underscored word to camelized word" do
    assert_equal "AClassName", "a_class_name".camelize
  end
end
