Testing a singleton method

ruby-talk
1

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?

I'm not exactly sure what you are trying to test, but this works:

   def test_singleton_method
     string1 = "hello"
     string2 = "world"
     def string1.only_one
       puts "PLEASE WORK"
     end
     assert string1.respond_to?(:only_one)
     assert !string2.respond_to?(:only_one)
   end

Could you post more context?

Chances are the singleton you *think* you're testing is not the same instance you actually *are* testing.
