Obviously the raffle for some reason is not defined, but however when i run the code without the last describe block, it did once work fine, however now when i try to replicate what i did earlier in removing the block of code, its now not fixing it. Any help or insight into why this is happening, would be greatly appreciated, as ive tried quite extensively to fix it myself, may just be a silly issue. But i dont believe theres any issue with the packages im using, because when i copied the example code in the repository, it worked fine, albeit with a few errors because of different names in my solidity functions.

@devcaii Please leave your repository link so I can test it locally.

Hey, I had the same issue, then i realised vs code inserted for me on top of my "test" file:
const { it } = require("node:test")

Once I deleted this line it solved my issue.
I see in your file you have something quite similar:
const { beforeEach } = require("node:test")

I think you should get rid of this line
