Summary

Environment have to call disconnect during teardown otherwise it will generate a warning:

A worker process has failed to exit gracefully and has been force exited. This is likely caused by tests leaking due to improper teardown. Try running with --detectOpenHandles to find leaks. Active timers can also cause this, ensure that .unref() was called on them.

Test plan

Just docs update ✌️
