- I have read and agree to Mocha's Code of Conduct and Contributing Guidelines
- I have searched for related issues and issues with the
faqlabel, but none matched my issue. - I have 'smoke tested' the code to be tested by running it outside the real test suite to get a better sense of whether the problem is in the code under test, my usage of Mocha, or Mocha itself.
- I want to provide a PR to resolve this
Expected

If run 73k tests, then everything works
Minimal, Reproducible Example
you can reproduce the problem like this
git clone git@github.com:sanchezzzhak/node-device-detector.git
npm i
node tests/tools/update-fixtures.js
npx mocha tests/*.spec.js
Versions
mocha 10.3.0 or 9.1.3
node 20.10.0
Additional Info
No response
I found the reason by downgrading the node js version, which showed that there is an infinite loop for test functions.
There is no problem.
