Look at fork history

I am getting same issue.

"sumo" doesn't end with "omo", neither "ails" ends with "fails" so no, they shouldn't return True at all. Not a kata issue.

And I don't know where your read you should only evaluate the last 2 characters:

Complete the solution so that it returns true if the first argument(string) passed in ends with the 2nd argument (also a string).

That's a wrong assumption on your part.

Looking at your test cases, some of them return False yet ideally they should return True. Casing point, Test case 1 "sumo", "omo" and test case 4 "ails", "fails".
These instances should return True. I dont understand why they return False. From the instructions, the last 2 characters of the text should end with the 2nd argument().
It's either the test cases are wrong or the instructions are not clear.

This is not how you raise an issue. You do not give any details. Do you expect us to read your mind ?

The test cases seem to have a bug. They're not consistent
