Trying to pass a unit test;

 def test_singleton_method
    string1 = "hello"
    string2 = "world"

    assert string1.respond_to?(:only_one)
    assert !string2.respond_to?(:only_one)
  end

====

my code to pass it:

  string1 = "hello"
  string2 = "world"

def string1.only_one
  puts "PLEASE WORK"
end


===

yet, this doesn't work, is there something I'm missing?
