Q:

Dynamic Method Call within define_method

I'm rather new to ruby, but am in a situation where I have many repetitive methods.  In attempting to DRY out my code I came up with something like the following:
class Foobar
  def some_method
    #
  end

  def some_method2
    #
  end

  def some_calculation
    #
  end

  [:some_method_test, :some_method2_test].each do |method|
    define_method method do
      return self.send(method.to_s.chomp "_test") / some_calculation
    end
  end
end

My question is regarding the .to_s.comp-- is there another way of writing this and accomplishing my goal? 

A:

Yes, you could start with the original name. 
[:some_method, :some_method2].each do |method|
  define_method :"#{method}_test" do
    return self.send(method) / some_calculation
  end
end

Note that this kind of metaprogramming usually doesn't make much sense unless you have a very large number of trivial methods.
