Code change:
The test variable here should be prefaced with an or something like that to prevent colliding with a common user variable name. Valid code should pass No response All No response_
From the individual tests: can be moved to the . This alone would be enough to make it not affected by such collision. Additionally using underscore after that, while not necessary also would be fine.
This is entirely user written code above. The user's choice of variable name conflicts with the variable name in the test suite, so we need to use a less common variable name in the test suite. A leading underscore is how I've seen that done in most challenges.
Whoops - this one was my fault haha.
To confirm the fix: Within the , all instances of the variable in the tests should be changed to .
I have this minor fix Please review Thanks
