Open handles with Jest configuration

[4rokis]

I am trying to set up a typescript with jest configuration. However, as soon as i have switched to jest i am getting this error. My understanding is that i should clean something up. Do you have any idea what? Happens on pure JS as well.

Jest has detected the following 2 open handles potentially keeping Jest from exiting:

I'm having the same issue. For local tests it is a superficial issue but in CI (GitHub Actions) it appears to be blocking my tests from completing.

There is something here to disconnect the server:

openzeppelin-test-environment/src/ganache-server.ts

Line 33 in 08c0b34

process.on('disconnect', () => {

I just can't figure out how to trigger it

For CI, I added --forceExit to make sure the tests complete.
