Mocha Tests unexpected error

Question

My tests where running well but not when I run yarn hardhat test, I get the error below.

Error

An unexpected error occurred:

TypeError: describe is not a function

I think it's a dependency issue. I have tried different versions of mocha but nothing works.

What could be the issue?
