Sorry, fixed ;-)

Please replace check_cheat in the sample tests with Test.assert_equals.

getting this error when i try and run the sample tests in Ruby:

main.rb:25:in `block in <main>': undefined method `check_cheat' for main:Object (NoMethodError)
	from main.rb:25:in `each'
	from main.rb:25:in `<main>'

it's my initial formation, yes. ;)

thanks, and thanks for the kata :) are you a chemist??

Hi,

I'm sorry to inform you that your solution is now invalid: I realized I did a small mistake in the design of the Atom class which needed the eql? method. If you wanna make your solution valid again, just add this to your Atom class:

def eql?(other)  return self == other end

Cheers,
