Thanks for your reply :). Language is Golang. I don't know if there's especially a test with the title itself but there is quite a few with punctuations. In those tests, the punctuation is reversed (or 'spinned') aswell (ie. "I like .azzip" instead of "I like azzip." like the title suggest).

Changing the title sometimes breaks (or broke) some things. This is in the kata description:

Strings passed in will consist of only letters and spaces.

When you say:

it should be "Stop gninnipS My !sdroW" like expected in tests

Is there a language where such test exists?

Thanks a lot. I was confused as the instruction doesn't say anything about the repeated words but now i get it. thanks

Your code fails when the last word is repeated in the sentence.
