Kata

I had this problem too. Either the instructions or the test case needs to be fixed. Kata authors need to be aware that this makes their katas annoying and unenjoyable. Please be explicit about what you expect out of our code and be consistent in your test cases!!

The instruction says: 'If hash does not contain at least one of the key given as an argument, method should raise an exception.'. In the test I gave two keys: one is correct (it is present in the hash), the second is not present in the hash. So at least one of the given key is not present in the hash. I don't see error in the description. Do you think that description:

'If any of the keys given as an argument is not present in the hash, the method should raise the an exception'.

will be more clear?

hh9 - it's really not so easy to create kata and make it clear for everyone. I see that you haven't create any yet. Please try and you will see :)

If any of the keys given as an argument is not present in the hash, the method should raise the an exception

Yes, this is much clearer. Although these might be slightly better:

If a key given as an argument is not present in the hash, the method should raise an exception

or

If any of the keys given in the argument are not present in the hash, the method should raise an exception

Thanks for the response!

Thank you! I'm glad you like it :)

Agree. It makes more sense this way.
