The kata now gives proper assertion messages and your solution is wrong. But please make sure to join with a normal space and not \u00A0.

Both of your solutions pass without problems so I'll close this issue.

I am going to close this issue as obsolete. I cannot reproduce the problem now, but it was most probably caused by overwriting the name test in concatenated test fixture, which does not happen anymore.

If the issue persists or comes back, please re-reaise.

Seems to be fixed.

The C# translation has been redone thorough the years, and most problems seem to be fixed: expected and actual were swapped, giving incorrect feedback, etc. OP's solution still fails because it's not valid.

Done for Python.

Closing as user error.

Yup, it was me, but I forgot to resolve the suggestion :|

I think it was hobs who approved it

Approved by someone.

Approved.

Python fork which adds random tests

Added an assertion which invalidates such "solutions".

A recent update has been published which fixes this issue ^^

OP's code is not correct, it contains a trailing newline.
