The instructions were to fix this bad code with a method_missing method.

method_missing.rb

class Person
  def initialize(name, age, incoming_race)
    @name = name
    @age = age
    self.race = incoming_race
  end

  def nam
    @name.split.map(&:capitalize).join(" ")
  end

  def agE
    @age
  end

  def method_missing(m, *args)
    if m.to_s =~ /name/
      self.nam
    elsif m.to_s =~ /age/
      self.agE
    elsif m.to_s =~ /race=/  #So, when person.race= is called, @race is assigned to the argument
      @race = args[0]        #Kind of like attr_writer
    elsif m.to_s =~ /race/
      @race.capitalize       #like attr_reader
    else
      super
    end
  end
end

person = Person.new("kurt vonnegut", 89, "caucasian")

assert_equal person.name, "Kurt Vonnegut"
assert_equal person.race, "Caucasian"
assert_equal person.age, 89
