Which failing tests?

"Maybe you should see your code"
You're probably right, as is almost always the case. However, if you found my comment on the kata 'requiring work' in some way offensive, I apologise; it could have been phrased more politely. Your response felt passive aggressive and not at all constructive. If you have constructive advice, I'm all ears.

Thanks

Similarly experiencing randomly failing tests. This kata needs some work before I could recommend it, I'm afraid
