# The Java Driven Developer 

class Person
  @name = ""
  
  def get_name 
    return @name
  end
  def set_name 
    return @name
  end
  
end

# Result

person = Person.new
person.set_name = "Juan"
person.get_name == "Juan" # true 
person.get_name == "Carlos" # false

# The Friendly Style Driven Developer

class Person
  attr_accessor :name
  
  def name_is_equal_to(name)
     name == @name
  end
  
end

# Result

person = Person.new
person.name = "Juan"
person.name_is_equal_to "Juan" #true
person.name_is_equal_to "Carlos" #false

# The Metaprogramming Driven Developer

class Person
  def method_missing(method, *args, &block)
    parsed_method = method.to_s.split("_") 
    if method.to_s[-1] == "?"
      return instance_variable_get("@name") == parsed_method.last[0..-2]
    else 
      instance_variable_set("@name", parsed_method[1]) if parsed_method.first == "is"
    end
  end
end

# Result 

person = Person.new
person.is_Juan
person.is_Juan? # true
person.is_Carlos? # false

# The Minimalist Driven Developer

class Person
  attr_accessor :name
end

# Result

person = Person.new
person.name = "Juan"
person.name == "Juan" # true
person.name == "Carlos" # false

# Functional Driven Developer

Person = Struct.new(:name)

# Result

person = Person.new("Juan")
person.name = "Juan"
person.name == "Juan" # true
person.name == "Carlos" # false
